A landmark former orphanage site in Surrey Hills could be transformed into a new residential community under plans lodged by <a href="https://www.apartments.com.au/developers/antipodean-land-developments">Antipodean Land Developments</a> that would deliver 76 apartments and townhouses while restoring some of the suburb's most significant heritage buildings.

The burgeoninng Melbourne-based developer has submitted plans for the 9,158 sqm site at 1 Kent Road and 24 Durham Road, home to the former St Joseph's Home for Destitute Children, a historic institutional complex dating back to the late 19th century. The proposal seeks to adaptively reuse several heritage buildings while introducing two new four-storey residential buildings set within extensive landscaped grounds.

Designed by <a href="https://www.apartments.com.au/architects/woods-bagot">Woods Bagot</a> and Kerstin Thompson Architects, the project has been conceived as a contemporary residential village embedded within a restored heritage precinct. The development team describes the design approach as "The Village in the Garden," with new buildings positioned among mature landscaping by OCULUS and significant heritage structures.

The proposal would deliver 76 dwellings comprising a mix of apartments and duplex-style residences, significantly increasing housing supply on one of the largest privately held residential landholdings in Surrey Hills. The development includes 127 car spaces, 24 bicycle spaces and more than 1,000 sqm of communal amenity, with the existing chapel building earmarked for conversion into resident facilities.

According to the planning submission, the project centres on the restoration and adaptive reuse of the site's most significant heritage assets, including the original c.1889 St Joseph's building, the chapel designed by architect Augustus Andrew Fritsch, and the historic brick perimeter walls and entry gates. The proposal also incorporates the retention of other contributory buildings including the former infirmary and school building.

Tract Consultants, in the planning report accompanying the application, said the scheme had been shaped through extensive heritage analysis and design development.

"The shared vision for the Site by the project team has culminated in a scheme which successfully breathes life back into a historic site while delivering upon the objectives of Victoria's Housing Statement in a carefully curated and contextually responsive manner."

The proposal is being assessed under Victoria's Significant Residential Development with Affordable Housing pathway. As part of the application, three per cent of the project's residential development cost would be contributed to the Social Housing Growth Fund. The development would also provide a diverse mix of one, two and three-bedroom residences targeting a broader range of buyers than typically found in Surrey Hills' detached housing market.

Sustainability initiatives include an anticipated 66 per cent BESS score, natural cross-ventilation to 80 per cent of apartments, 28 per cent deep soil landscaping and a canopy cover outcome exceeding local planning requirements. The proposal also sets aside more than 1,083 sqm for communal indoor and outdoor resident amenity spaces.

Planning documents describe the property as one of the largest underutilised residential sites in Surrey Hills, arguing it presents a rare opportunity to introduce "missing middle" housing in an established inner-eastern suburb while preserving and revitalising a significant heritage precinct.

Antipodean Land Developments has built a reputation for design-focused residential projects across Melbourne, particularly in the medium-density sector. Previous developments include Neighbourhood in Brunswick East, delivered with Breathe Architecture, and Balfe Park Lane, designed by Kerstin Thompson Architects.

They've been very active in site acquisition as they build out their future development pipeline. They recently launched Thornubury House, 45 apartments above a mix of commercial, retail, and food and beverage tenancies, and have plans for a boutique project in Fitzroy and another <a href="https://www.apartments.com.au/news/vic/antipodean-plan-apartments-for-deepdenes-missing-middle-on-whitehorse-road">"missing middle" project</a> on Deepdene's Whitehorse Road.

Developer <a href="https://www.apartments.com.au/developers/auyin-property-development">Auyin</a> is the latest to turn to the Victorian Government's Development Facilitation Program in an effort to secure approval for its long-planned, mixed-use project in Elsternwick.

In 2018, Auyin lodged plans with Glen Eira City Council for a 14-storey building, however Council approved a reduced eight-storey scheme. A subsequent VCAT appeal in 2019 upheld the eight-storey height limit.

The project was later amended to nine storeys, but Auyin is now seeking to revive something closer to its original vision. The developer argues that the planning context has evolved significantly over the past decade, particularly within the Elsternwick Activity Centre, where higher-density development has increasingly been encouraged along Glen Huntly Road.

The proposal would transform the 1,239 sqm site at <a href="https://www.apartments.com.au/new-apartments/7-12-horne-street-elsternwick-vic-3185">7-15 Horne Street</a>, opposite Elsternwick Railway Station, into a 13-storey residential and retail development designed by CBG Architects, with 40 apartments

The site currently comprises three commercial properties.

<img alt="First look: 13-storey mixed-use tower planned for Elsternwick activity centre" data-entity-type="file" data-entity-uuid="5f465dd4-509b-4082-a669-0253b313914b" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/elsternwick%20podium.png?VersionId=72frWi0SmQ5AVJ3ARRhX5ILUYObhTm7x" />

The proposed apartment mix comprises 25 two-bedroom and 15 three-bedroom residences above 200 sqm of retail space at ground level. Residents would have access to a 90 sqm wellness facility, a 351 sqm communal indoor and outdoor terrace on the third level, and extensive landscaped areas throughout the development. A publicly accessible 135 sqm plaza would be created on the north-east corner of the site, providing seating, landscaping, and a new gathering space adjoining Horne Street.

The design adopts a four-storey podium that references the finer-grain character of the surrounding streetscape, with the upper tower recessed behind generous setbacks on all boundaries.

<img alt="First look: 13-storey mixed-use tower planned for Elsternwick activity centre" data-entity-type="file" data-entity-uuid="e637e763-2abc-4c34-a0aa-5c7ad36fae18" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/elsternwick%20open.png?VersionId=J1AoOpZgTyaF.KeeFSX6lMjEScX8KKRi" />

A key element of the proposal is the reconfiguration and widening of the surrounding laneways. Vehicle access would be retained from Lois Lane, with upgraded pedestrian connections linking Ross Street and Horne Street. The development would provide 58 residential car spaces, two retail car spaces, and 52 bicycle spaces across two basement levels and ground-floor facilities.

Architecturally, the building draws inspiration from the established character of Elsternwick Village. The façade combines dark charcoal brickwork, textured concrete, bronze-toned metal detailing, and extensive planting integrated into podium and tower levels. The design also incorporates a chamfered corner treatment and publicly accessible plaza intended to strengthen pedestrian activity around the station precinct.

Elsternwick's last new development completion was&nbsp;EVA Elsternwick by Pitard late last year. <a href="https://www.apartments.com.au/developers/milieu-property">Milieu</a> is working away on its nature-led neighbourhood, <a href="https://www.apartments.com.au/new-apartments/elsternwick-gardens-by-milieu-8-gordon-street-elsternwick-vic-3185">Elsternwick Gardens</a>, on Gordon Street, with its first stage expected to complete next year.

<a href="https://www.apartments.com.au/new-apartments/otium-parkdale-123-125-como-parade-east-parkdale-vic-3195">Otium Parkdale</a>, the 13-residence boutique development by&nbsp;<a href="https://www.apartments.com.au/developers/huxtable-property">Huxtable Property</a>, has entered its final stages of delivery, with completion expected within the coming month and more than half of the residences sold.

The Como Parade East project is nearing the finish line at a time when opportunities to purchase new apartments in <a href="https://www.apartments.com.au/developments/parkdale-vic-3195">Parkdale</a> remain exceptionally limited. Fewer than 10 per cent of dwellings in the bayside suburb are apartments, making developments like Otium a relatively rare addition to a market traditionally dominated by detached housing.

[smartcode_project:default project_id=134974 project_image_fid=5427]

The three-level development comprises 13 residences, including ten two-bedroom apartments and three larger three-bedroom homes, all positioned above a secure basement car park.

Designed by <a href="https://www.apartments.com.au/architects/almeida-architects">Almeida Architects</a> with a strong connection to its coastal surroundings, Otium combines red brick, exposed concrete and dark metal detailing with integrated landscaping and greenery. Expansive glazing, generous balconies and terraces have been incorporated throughout the design to maximise natural light and reinforce indoor-outdoor living.

Inside, the residences feature engineered European oak flooring, natural and reconstituted stone benchtops, Bosch kitchen appliances, ducted heating and cooling, lift access and secure entry systems. The larger three-bedroom residences on the upper level have been designed with house-like proportions, while the two-bedroom apartments prioritise functionality, flexibility and low-maintenance living.

[smartcode_project:default project_id=134974 project_image_fid=5421]

The project is now in its final stages, with <a href="https://www.apartments.com.au/builders/labco">Labco</a> completing the remaining landscaping and external finishing works following the completion of the residences' interiors.

Otium's location within the heart of Parkdale continues to underpin its appeal. Residents will be just steps from local cafés, restaurants, shops and the newly elevated Parkdale Station, while the beach is less than a kilometre away.

With the project tracking ahead of schedule, buyers can currently secure a residence with a five per cent deposit and benefit from settlement terms of up to eight months. The advanced stage of construction also provides buyers with the opportunity to walk through the near-complete residences and experience the quality and finishes firsthand ahead of completion.

A new boutique apartment development is entering the market in <a href="https://www.apartments.com.au/developments/chermside-qld-4032">Chermside</a>, with Brisbane-based developer <a href="https://www.apartments.com.au/developers/ausdev">Ausdev</a> bringing 33 residences to a well-connected pocket of Brisbane's north.

<a href="https://www.apartments.com.au/new-apartments/parkdrive-apartments-chermside-25-sammells-drive-chermside-qld-4032">Parkdrive Apartments</a>, at 25 Sammells Drive, will comprise a mix of one- and two-bedroom residences positioned within walking distance of Westfield Chermside, The Prince Charles Hospital, and Bradbury Park.

Established in 1989, Ausdev has a long-standing presence across both development and construction, with Parkdrive Apartments representing its latest residential project in Brisbane's northern suburbs.

[smartcode_project:default project_id=152125 project_image_fid=363778]

The development has been designed around open-plan living and natural light, with residences featuring stone benchtops, timber cabinetry, BOSCH appliances, and private balconies that extend the living areas outdoors.

Kitchens are positioned as the centrepiece of the homes, incorporating natural material palettes and integrated appliances, while bathrooms have been designed with a focus on functionality and understated finishes.

Residents will have access to a communal barbecue and entertaining area on Level 3, providing shared outdoor space within the development. Secure parking and lift access are also incorporated into the building.

The project will deliver a limited collection of 33 apartments, with one-bedroom residences priced from $749,000.

[smartcode_project:default project_id=152125 project_image_fid=363782]

Beyond the building itself, the location places residents within easy reach of several of Chermside's key amenities. Bradbury Park is around 350 metres away, while Westfield Chermside is approximately 1.3 kilometres from the site. The Prince Charles Hospital is located within 750 metres, and the Chermside Bus Interchange is around 1.5 kilometres away, providing connections across Brisbane.

Parkdrive Apartments adds to the growing residential pipeline in Chermside, a suburb that continues to evolve as a major retail, healthcare, and transport hub for Brisbane's north.

<a href="https://www.apartments.com.au/developers/skymark-group">Skymark</a>'s boutique Cronulla development Solis has secured a 10-year Latent Defects Insurance policy through Resilience Insurance, providing buyers of the 16-residence building on Ewos Parade with structural and waterproofing protection that extends a decade beyond the building's completion.

Currently under construction and due for completion in late 2027, <a href="https://www.apartments.com.au/new-apartments/solis-cronulla-8-ewos-parade-cronulla-nsw-2230">Solis</a> is one of a small number of new developments in the Sutherland Shire to carry Resilience LDI coverage, a distinction that carries increasing weight as buyer confidence in the off-the-plan sector continues to be shaped by how developers stand behind their product.

Latent Defects Insurance, which entered the Australian market in 2022 when Resilience Insurance was approved to offer the cover, protects buyers against major structural or waterproofing defects for ten years post-completion. Unlike traditional statutory warranties, it operates as a first-resort policy, if a covered defect arises, the insurer responds directly, without the buyer needing to pursue the builder or developer through a lengthy claims process.

Resilience Insurance CEO Corey Nugent has noted that the product addresses something fundamental to the new apartment market.

"The overarching feedback from prospective buyers in the new development space is that they want more confidence and assurances around the quality of the build," Nugent says.

"Resilience Insurance Latent Defects Insurance not only gives them complete peace of mind for 10 years, but it shows the developer they are buying from is standing by their product."

[smartcode_project:default project_id=150499 project_image_fid=370898]

For Solis, the Resilience LDI policy adds a meaningful layer of accountability to an already considered project. The development comprises nine two-bedroom and seven three-bedroom residences, including one dual-level three-bedroom apartment, across a five-storey building on Ewos Parade, positioned between Shelly Beach and South Cronulla.

Garden apartments connect directly to private landscaped courtyards, while upper-level homes capture beach views to the east from level four and above.&nbsp;

All 16 residences include at least one balcony or courtyard, and select apartments on the upper floors feature bar areas and secondary flexible living spaces.

Hiba Sander, Managing Director of Skymark, says Solis offers a rare balance, nestled between the quiet beauty of secluded beaches and the lively charm of South Cronulla's esplanade.

"It's a place to choose your pace and live gracefully, seaside'," Sander says.

[smartcode_project:default project_id=150499 project_image_fid=370900]

The architecture, designed by <a href="https://www.apartments.com.au/architects/ida-design-group">IDA Design Group</a>'s Michael Trinh, draws from the natural erosion patterns of <a href="https://www.apartments.com.au/developments/cronulla-nsw-2230">Cronulla</a>'s sandstone headlands, translating the organic forms of the coastline into soft curves, pavilion-style massing, and a material palette chosen for longevity in a salt-tinged environment.&nbsp;

Textured natural stone, soft renders, and timber-look battens reference the tones of the surrounding cliffs, while the building has been oriented to maximise natural light and passive ventilation, with primary living spaces facing north and east to capture morning sun and sea breezes.

"At Solis, our aim was to create architecture that feels quietly confident, grounded in natural materials like stone and timber, and elevated by light and landscape," Trinh says.&nbsp;

"The buildings are designed to sit gently within their coastal surrounds, with expansive glazing and abundant greenery creating a seamless dialogue between inside and out."

[smartcode_project:default project_id=150499 project_image_fid=370897]

Interiors by <a href="https://www.apartments.com.au/architects/hot-black">Hot Black</a> carry the same material language through to every room. Kitchens feature integrated Gaggenau appliances, sculpted stone benchtops, and Lo &amp; Co joinery, while bathrooms feature natural stone, timber, and brushed metal finishes.&nbsp;

Hot Black Founder and Design Director Sophie Safrin describes the intent as one of considered restraint: "At Solis, every detail has been thoughtfully considered to create a timeless coastal retreat, calm, refined, and effortlessly liveable. From natural finishes to seamless indoor-outdoor flow, Solis offers a quiet elegance that's deeply connected to its surroundings.

The landscape, designed by Julian Brady of <a href="https://www.apartments.com.au/landscape-architect/sitedesignstudios">Site Design Studios</a>, treats green space as an integral part of the resident experience rather than an afterthought.&nbsp;

"Gentle curves and layered native plantings mirror the ebb and flow of the ocean," Julian Brady says, "creating a serene connection between architecture and place."&nbsp;

Coco Republic has provided bespoke furniture packages tailored to the project's coastal palette.

[smartcode_project:default project_id=150499 project_image_fid=370899]

Skymark has an established track record in the Sutherland Shire, with a portfolio spanning Cronulla, Woolooware and Burraneer that includes Isla, Sylva, Bask, Shells, Sula and Mist. Securing LDI on Solis reflects a broader shift in how the developer is positioning its buildings to buyers, at a time when Resilience Insurance expects the policy to become mandatory in New South Wales by 2028.

Sales at Solis are launching soon through Ray White Projects, with an official event scheduled for 11 June. Enquire for more information.

In the next four weeks the NSW Government's Planning System Acceleration Program will have fast-tracked over 100 major projects and planning proposals since April.
They've determined 90 major projects and proposals in the last five months, and in the next four weeks another 11 will be determined as part of the sixth tranche. 
The PSAP have said they have already created 50,000 jobs and injected $25 million in to the economy since April.
If the latest sixth tranche is approved for the next 11 projects, these could result in a further $527 million worth of investment and the potential to create more than 1,400 jobs. 
Minister for planning and public spaces Rob Stokes said the planning system had been a key economic lever in the NSW Government’s immediate response to the pandemic, driving the state and the rest of the country to a strong economic recovery by accelerating a pipeline of projects.  
“COVID-19 has had a devastating impact on our lives and the economy and getting shovel-ready projects out the door to help NSW rebound from this crisis has been a critical priority,” Mr Stokes said. 
“Our short-term drive to create a steady supply of jobs and investment has been a great success, with work already starting on construction sites across the State.  
“Our focus now turns to a medium-term response, which will speed up and add greater certainty for more complex projects with longer timeframes of between six months and two years.  
“With our nation in a recession, boosting the economy and creating jobs is more important than ever.”
The projects selected for accelerated assessment in tranche six include:
- Upgrade of the Fort Street Primary School
- Rezoning in St Mary’s for 500 new homes that will have an economic benefit of $126 million and create 250 jobs
- Rezoning in Appin for low density housing and environmental management of a biodiversity corridor, including 39 hectares protected for conservation
- Construction of 18-storey mixed-use student accommodation near the University of Sydney for 488 students, contributing $62 million and creating 245 jobs 
- New Oran Park Town Centre in Camden, including dedicated public space, contributing $30 million and creating 60 jobs
“If approved, these 11 projects will mean that we’ve fast-tracked determinations of more than 100 projects since the accelerated program began in April,” Mr Stokes said.

The conflict within the NSW Coalition over the “Koala Environmental Planning Policy” may be just what the Berejiklian Government needs to adjust their policy settings and focus clearly on delivering a Post COVID-19 recovery.
Since becoming Planning Minister for the second time in March 2019, Rob Stokes, has talked the talk on planning reform and speeding up the system, but he is yet to deliver anything substantial. This new Koala Planning Policy is one of the first SEPPs he has delivered.  It was done with good intent – but like so many of his policies, the consultation was undertaken with blinkers on. 
The Koala SEPP was well motivated when it was made in late 2019 at the height of the tragic bushfires.  But the unintended consequences, the economic consequences, the devil in the detail, have all come back to bite.
Just as increased prescriptive regulation reduces feasibility and therefore housing supply – there are always unintended consequences of planning regulation. The National Party are making that abundantly clear today.
The NSW Productivity Commissioner (an independent arm of the Treasury) has been asked to examine the impact of planning on the economy in NSW and he has already delivered a damming assessment through the publication of his Green Paper.  But rather than learn from this assessment, planning in Sydney seems to be taking a “nanny-state” approach to housing.  Costs are being pushed up by even greater regulation. 
The Government talks about its desire to improve housing affordability, yet it drives prices up by constraining supply through the slowest planning system in the nation which is delivering lower and lower levels of new housing approvals.
The anti-development mantra was politically fashionable in the lead-up to the 2011 election when the public were rightly sick and tired of the lack of transport and social infrastructure to support population growth.  But we have seen investment in those areas and the economy is everything now.
The Premier is cautious about development and this reflects the views of her North Shore base.  But the last decade has seen a consistent under supply of housing when compared to population growth.  This has driven up housing prices.  There were only two years out of the last 15 when new housing matched the demand from population growth.  
Ironically the Koala SEPP, which the NSW Nationals are so upset about, is an example of the powers available to the Minister for Planning, to make SEPPs, should he wish to use them to stimulate the economy.
The is no-one in the NSW Opposition standing up for jobs and private sector investment – so the Government needs to have a fight with itself to correct policy settings which have drifted away from the primacy of the economic imperative. 
If this political stoush helps shift the NSW Cabinet’s mind-set towards a pragmatic approach which is focussed on economic growth, jobs growth, growth in housing supply and growth in new work-places – then that will be a stoush well worth having.
Tom Forrest is the CEO of Urban Taskforce.

EXPERT OBSERVER
We were heavily involved in the consultation program for Melbourne’s long-term land-use plan, Plan Melbourne. The idea that resonated most with many participants was shaping the city as a series of 20-minute neighbourhoods.
People generally loved the thought that most (not all) of the things needed for a good life could be within a 20-minute public transport trip, bike ride or walk from home. These are things such as shopping, business services, education, community facilities, recreational and sporting resources, and some jobs (but probably not brain surgery).
Creating a city of 20-minute neighbourhoods is a key policy direction of <a href="https://www.planmelbourne.vic.gov.au/" target="_blank">Plan Melbourne 2017-2050</a>. As the plan <a href="https://www.planmelbourne.vic.gov.au/highlights/healthy,-vibrant-and-inclusive-neighbourhoods" target="_blank">states</a>:
The 20-minute neighbourhood is all about ‘living locally’ – giving people the ability to meet most of their everyday needs within a 20-minute walk, cycle or local public transport trip of their home.
This planning idea has gained Melbourne recognition in international planning circles. For example, Singapore’s recent <a href="https://www.lta.gov.sg/content/ltagov/en/who_we_are/our_work/land_transport_master_plan_2040" target="_blank">Land Transport Master Plan 2040</a> is based on shaping the city and its transport systems to achieve 20-minute towns within a 45-minute city. Officials who prepared the report have acknowledged to one of us Melbourne’s leadership with the concept.
The concept is not about travel by car. It is about active transport (walking, cycling) and the use of public transport. The goal is that this combination of modes would offer a reasonably sized catchment area in which people, jobs and services, including recreational opportunities and nature, are accessible.

Inner parts of Australia’s capital cities and parts of their middle suburbs already meet a 20-minute neighbourhood test. Very few of the outer suburbs would do so. However, new developments such as the <a href="https://www.greaterspringfield.com.au/">City of Springfield</a> in outer Brisbane are encouraging.
Key ingredients of 20-minute neighbourhoods
If outer suburbs, in particular, are to become 20-minute neighbourhoods, then two key requirements must be met.
First, local development densities need to be increased. This means ensuring minimum density levels of around 25-30 dwellings per hectare, which will better support local activity and services provision.
Consultations with council planners suggest new developments in Melbourne’s outer north, for example, are typically running at about 18 dwellings. The density of developments was about 12 just a decade ago.
Accompanying more dense residential development is the need to integrate a mix of uses within these neighbourhoods. This would bring more jobs and services close to where people live. They would also have a range of housing to support a mix of household types, income levels and age groups.
So we need not just density but also a mix of land uses within a neighbourhood. This is often known as density plus diversity.
Second, local public transport service levels need to be greatly improved. To achieve 20-minute neighbourhoods requires local weekday public transport services running every 20 minutes or better, from around 5am until 11pm (start of last run). That’s a minimum of 55 services per stop per day per direction.
The map below shows very few parts of outer Melbourne have services anywhere near this level.
<a href="https://images.theconversation.com/files/313621/original/file-20200205-20014-ppvhia.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/313621/original/file-20200205-20014-ppvhia.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt=""></a>

What would it cost to achieve?
Gross funding increases of about 50% for local public transport services (essentially buses) would be needed to meet this basic service standard for 20-minute neighbourhoods across Melbourne. Based on scaling up the <a href="https://s3-ap-southeast-2.amazonaws.com/budgetfiles201920.budget.vic.gov.au/2019-20+State+Budget+-+Service+Delivery.pdf" target="_blank">cost of current bus services</a> in Melbourne, we estimate the cost would be about A$250 million a year, or A$4 billion over the long term, in present values.
This is a modest amount compared to current capital commitments for rail. These total <a href="https://s3-ap-southeast-2.amazonaws.com/budgetfiles201920.budget.vic.gov.au/2019-20+State+Budget+-+State+Capital+Program.pdf" target="_blank">A$30-40 billion</a>, depending on what share of the <a href="https://s3-ap-southeast-2.amazonaws.com/budgetfiles201920.budget.vic.gov.au/2019-20+State+Budget+-+State+Capital+Program.pdf" target="_blank">cost of level-crossing removals</a> is attributed to rail. Development of the government’s proposed <a href="https://suburbanrailloop.vic.gov.au/en" target="_blank">Suburban Rail Loop</a> around the city will add an <a href="/news/victorian-government-says-melbournes-suburban-rail-loop-will-be-an-operationally-independent-railway" target="_blank">estimated A$50 billion</a>. Annual payments for metropolitan train services add <a href="https://s3-ap-southeast-2.amazonaws.com/budgetfiles201920.budget.vic.gov.au/2019-20+State+Budget+-+Service+Delivery.pdf" target="_blank">A$1.1 billion</a>.
Trains now carry only <a href="https://s3-ap-southeast-2.amazonaws.com/budgetfiles201920.budget.vic.gov.au/2019-20+State+Budget+-+Service+Delivery.pdf" target="_blank">twice as many passengers</a> as buses do. So the suggestion that an extra A$4 billion or so be spent on bus services, in capitalised terms, is very modest compared to the commitments being made to rail. The amount includes an allowance for infrastructure works to improve operating speeds – such as bus lanes and B-lights, which give buses priority through intersections.
The tram network could make an equally strong argument for extra funding, relative to trains, given the relative passenger loads carried and <a href="https://s3-ap-southeast-2.amazonaws.com/budgetfiles201920.budget.vic.gov.au/2019-20+State+Budget+-+State+Capital+Program.pdf" target="_blank">small new capital program</a> in place for trams (hundreds of millions rather than tens of billions).
Melbourne has recently had a massive jump in spending on capital projects, particularly transport projects. This investment is needed to tackle the backlog from years of neglect and cope with one of the <a href="https://sustainable.unimelb.edu.au/publications/research-papers/melbourne-how-big" target="_blank">fastest population growth rates</a> of any similar-sized city in the developed world.
The 2019-20 state budget, for example, suggests <a href="https://s3-ap-southeast-2.amazonaws.com/budgetfiles201920.budget.vic.gov.au/2019-20+State+Budget+-+State+Capital+Program.pdf" target="_blank">capital spending will average A$13.9 billion a year</a> over the four years to 2022-23. It was less than A$5 billion a year from 2005-06 to 2014-15.
It’s about more than walkability
In stark contrast, implementation of 20-minute neighbourhoods has been limited to <a href="https://www.planmelbourne.vic.gov.au/current-projects/20-minute-neighbourhoods/pilot-program" target="_blank">three pilot studies</a>, in <a href="/news">Strathmore</a>, <a href="/news">South Croydon</a> and <a href="/news">Sunshine West</a>. These studies appear to be focused heavily on developing walkable neighbourhoods, rather than on improving access by walking, cycling and public transport, which was the original intent of the idea.
Walkable neighbourhoods are an important part of 20-minute neighbourhoods, but only one part. Increased neighbourhood densities and more mixed-use development across local active transport and public transport catchments, together with better walking, cycling and local public transport opportunities, need far greater attention if 20-minute neighbourhoods are to be created in outer and middle suburbs.
We expect a much stronger focus at the neighbourhood level will deliver very high social, environmental and economic returns from small outlays. But, for this to be achieved, much greater urgency is needed.<img src="https://counter.theconversation.com/content/131193/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important; text-shadow: none !important;">

EXPERT OBSERVER
In 1988 the Australian Bureau of Statistics (ABS) projected a population of 25 million by 2050. Australia reached that estimate 30 years earlier. Our population grew by more than 400,000 in 2018-19, and the ABS now projects a population of 30 million by 2030.
At this growth rate, Australia will need to house an additional 16.8 million residents in the next 40 years. This is the equivalent of a new city the size of Canberra every year for the next 40 years – or a city the size of Darwin every 12 weeks.
Mike provides recommendations to governments and urban developers building sustainable cities that will avoid putting further strain on our existing capital cities, maintain our standard of living and health, provide local jobs, make housing attainable for every generation, save water and create safe streets for pedestrians and cyclists.
Mike’s 7 recommendations to building new cities that will ease the squeeze:
1. Locate new cities between Sydney and Melbourne. Mike says now is the time to think about potential sites for new cities. For instance, eight could be built along the Sydney-to-Melbourne high-speed rail service that is being considered by government. Connecting the two cities provides an opportunity to promote the ‘twin cities’ of Melbourne and Sydney, considered by many as the world’s most liveable and beautiful cities.
2. Build ‘urban’ cities from the start. Mike says new cities must be medium- to high-density from the outset, be connected within by sustainable forms of transport and offer local jobs. A specific rapid mixed use, walkable, urban city model is being advocated to Federal and State Governments by Consolidated Land and Rail Australia (CLARA) – a private group RobertsDay is assisting – which is offering solutions to re-balance Australia’s existing settlement and deliver new ways of planning and building liveable, sustainable, connected cities, transport and infrastructure.
3. De-centralise jobs. Mike says most land uses can now happily co-exist. However, any new cities that we build will require multiple ‘outer-suburb mixed use urban centres with mixed-use retail, commercial and residential areas that are transit-based, compact and walkable. This will ensure short commute times and avoid putting pressure on transport systems and roads. Mike says our existing cities – especially Sydney and Melbourne, where the cost of commuting and housing attainability is a major problem – would also benefit from additional outer-suburb mixed use urban centres.
4. Create low-water-use outdoor community spaces. Grass requires a lot of water. With water levels expected to be a major long-term issue, Mike says cities can better manage water usage by developing courtyard-style housing, and European-style outdoor community spaces (much like piazzas) that are water-wise through the use of materials such as pea gravel to replace turf and drought-tolerate plant species such as olive trees.
5. Build water-wise, medium-density homes. NSW planning minister Rob Stokes is pushing for more medium-density housing in the State. This will bring residents multiple benefits. Townhouses and courtyard homes, with their turf-free outdoor spaces, will result in a significant reduction in water usage. In contrast to apartment complexes, townhouses and terraces provide individual street frontages, allowing residents to feel connected to their neighbourhoods. If townhouses are designed like the successful terrace models in Sydney, Melbourne, Vancouver, Seattle and Toronto, homeowners will be able to capitalise on their properties by building 40 sqm granny flats above their garages.
6. Recognise walking and cycling as the privileged modes of transport. Townhouse communities can be designed with small streets at their rear providing access to garages. This minimises garages and driveways at the front of properties, enabling uninterrupted walking and cycling along tree-lined street frontages. This will improve safety and quality of life for pedestrians and cyclists. Imagine kids being able to safely walk to school again!
7. Strive to embrace the UN’s Sustainable Development Goals. All 193 United Nations member countries have adopted the 17 UN Sustainable Development Goals (SDGs), to be achieved by 2030. These SDGs envisage the delivery of sustainable cities and neighbourhoods, protecting the planet and ensuring prosperity for all. Mike says that the bushfires have raised our awareness internationally, and that we need to act on them now. The Federal Government, State Government and the urban development industry need to more comprehensively action the SDGs.

GUEST OBSERVATION
Around the world, the vast majority of people are flocking to cities not to dwell in their centres but to live in the new suburbs expanding their outer limits.
Reflecting this, from 2000 to 2015, the <a href="https://unstats.un.org/sdgs/report/2017/goal-11/" target="_blank">expansion of urbanised land worldwide outpaced urban population growth</a>. The result is <a href="https://unstats.un.org/sdgs/report/2017/" target="_blank">unprecedented urban sprawl</a>.
Expansive suburbs of single-family, freestanding housing are ubiquitous in countries such as Australia, the US and the UK. Most Australians still <a href="https://theconversation.com/becoming-more-urban-attitudes-to-medium-density-living-are-changing-in-sydney-and-melbourne-84693" target="_blank">aspire to own a large detached house</a> in the suburbs.
Public resistance to so-called infill development is unlikely to be overcome without a major change in how cities approach urban densification. We <a href="https://www.propertyobserver.com.au/https://www.springer.com/gp/book/9783030296001" target="_blank">advocate greenspace-oriented development</a>, or GOD, which provides substantial, public green spaces to serve surrounding higher-density neighbourhoods.
<a href="https://images.theconversation.com/files/299805/original/file-20191101-187907-jwuiia.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/299805/original/file-20191101-187907-jwuiia.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt=""></a>
Greenspace-oriented development correlates urban densification with significant, upgraded public green spaces. Author provided
We love our leafy suburbs
The “Australian dream” of owning your own home is often automatically associated with a detached house on a block of land. It’s seen as a mark of having “made it”.
For instance, a <a href="http://www.dhw.wa.gov.au/News/Pages/hwc.aspx" target="_blank">study in Perth</a> found that, if they had the money, 79% of people would prefer a separate dwelling and 13% a semi-detached option. Only 7% preferred flats, units or apartments.
Evidently, the suburban dream runs deep in the Australian cultural psyche. Australia is not alone in this. As a result of widespread preference for suburban living, globally we are not in the age of urbanisation but rather the age of suburbanisation.
Despite the enduring popularity of suburban life, several emerging crises threaten its dominance. These include the <a href="https://theconversation.com/to-protect-fresh-food-supplies-here-are-the-key-steps-to-secure-city-foodbowls-114085" target="_blank">destruction of agriculturally productive</a> and <a href="https://theconversation.com/squandering-riches-can-perth-realise-the-value-of-its-biodiversity-63933" target="_blank">biodiverse land</a> around expanding cities, <a href="https://theconversation.com/australian-city-workers-average-commute-has-blown-out-to-66-minutes-a-day-how-does-yours-compare-120598" target="_blank">ballooning commuting times</a> and service and public transport <a href="https://www.macrobusiness.com.au/2019/08/australian-infrastructure-expensive/" target="_blank">infrastructure costs</a>, and the <a href="https://theconversation.com/private-renters-are-doing-it-tough-in-outer-suburbs-of-sydney-and-melbourne-120427" target="_blank">concentration of socio-economic vulnerabilities</a> in outer suburbs. These areas also <a href="https://theconversation.com/living-liveable-this-is-what-residents-have-to-say-about-life-on-the-urban-fringe-111339" target="_blank">have poorer access</a> to jobs.

Why infill efforts are failing
To limit urban sprawl, the emphasis in most cities worldwide is on increasing urban density. In pursuit of infill development, planning strategies have focused mostly on <a href="http://www.tod.org/" target="_blank">transit-oriented development</a>. This approach focuses on higher-density development around public transport nodes and corridors.
Despite the widespread adoption of this ideology in Australia, many cities are <a href="https://dusp.mit.edu/publication/infinite-suburbia" target="_blank">not achieving</a> their <a href="https://uwap.uwa.edu.au/products/made-in-australia-the-future-of-australian-cities" target="_blank">infill targets</a>. In part, this is because transit-oriented development strategies suggest an “<a href="https://onlinelibrary.wiley.com/doi/full/10.1111/j.1745-5871.2006.00374.x" target="_blank">inflexible, over-neat vision</a>” of cities at odds with their “increasing geographical complexity”.
Much of the infill that has been achieved is through indiscriminate and opportunistic subdivision of individual suburban lots by “mum and dad” investors. This “<a href="https://www.tandfonline.com/doi/abs/10.1080/07293682.2016.1245201" target="_blank">background infill</a>” fails to achieve infill targets, does not reduce car use, erodes urban forests, and aggravates local communities. This has led to community resistance (the <a href="https://www.britannica.com/topic/Not-in-My-Backyard-Phenomenon" target="_blank">NIMBY</a> factor) and what one council official referred to as a “<a href="https://grattan.edu.au/report/city-limits-why-australias-cities-are-broken-and-how-we-can-fix-them/" target="_blank">public sullenness</a>”.
Higher density with a green focus
The principles of transit-oriented development are well established and valid. However, we <a href="https://www.propertyobserver.com.au/https://www.springer.com/gp/book/9783030296001" target="_blank">contend</a> that we need a complementary strategy, greenspace-oriented development, for achieving infill development. This approach would correlate urban densification with substantial, upgraded public green spaces or parks that are relatively well served by public transport.
Greenspace-oriented development builds upon the now well-recognised <a href="https://theconversation.com/higher-density-cities-need-greening-to-stay-healthy-and-liveable-75840" target="_blank">array of benefits</a> of green spaces for urban dwellers. Most importantly, it underpins approaches to making our cities more sustainable and liveable.
Australian suburbs do generally contain a reasonable number of parks. But these are typically underdesigned and underused. Many parks offer minimal amenity, often little more than large stretches of irrigated lawn and a scattering of trees.
<a href="https://images.theconversation.com/files/299807/original/file-20191101-102207-1w2nlod.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/299807/original/file-20191101-102207-1w2nlod.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt=""></a>
Before and after: in greenspace-oriented development, density and natural amenity are interwoven. Images courtesy of Robert Cameron. Author provided
We suggest redesigning parks to increase the naturalness, ecological function and diversity of active and passive recreational uses, which in turn can support higher-density urban areas. Indeed, it should increase the value of neighbouring real estate. With rezoning, this should enable greater local densification that is both commercially viable for developers and more attractive for residents.
Residents would then have an incentive to support well-designed infill development. When completed, each of these upgraded parks operates as a multifunctional, communal “backyard” for residents of a surrounding higher-density urban precinct.
<a href="https://images.theconversation.com/files/299806/original/file-20191101-102182-1ncjsyg.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/299806/original/file-20191101-102182-1ncjsyg.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt=""></a>
Before and after: parks become multifunctional communal ‘backyards’ for people living at a higher density around the park. Author provided
The lure of suburbia clearly remains strong for people around the world. If planners are to deal with the problems of sprawl, they need to increase urban density in a way that resonates with the leafy green qualities of suburbia that most people desire (at very least in Australia).
Transit-oriented development ideology relies on a false presumption that residents will trade the benefits of nature for the benefits of urbanity. We require a new vision of urban densification that responds to the urban, societal and ecological challenges of the 21st century and aligns with people’s preference for suburban living near nature.<img src="https://counter.theconversation.com/content/126204/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important; text-shadow: none !important;">

Greenspace-oriented development could make higher density attractive

<html><body>
EXPERT OBSERVERS
Not everyone wants to live in the inner city and it’s insulting to describe the outer suburbs as the fringe.
This was just one view from a recent workshop where a vision for Australia’s future cities was mapped out. It highlights that <a href="https://theconversation.com/liveable-cities-who-decides-what-that-means-and-how-we-achieve-it-48825" target="_blank">liveability means different things to different people</a>.
But what will the liveability of our cities be like in 40 years’ time? For the CSIRO report, <a href="https://www.csiro.au/en/Showcase/ANO" target="_blank">2019 Australian National Outlook</a>, the authors used scenario analysis to explore prospects for Australia in 2060. This demonstrates that business as usual will mean Australia’s economy and society sleepwalk into the future, a future made worse by failing to tackle major environmental threats.
The National Outlook report set out “five key shifts” – industry, urban, energy, land and culture – to prepare us for a better future.
Our research supports the need for these changes. These shifts are related and co-dependent. And, critically, they will all involve cities.
We argue, though, that we need more than “shifts” – we need transformation supported by <a href="https://www.tandfonline.com/doi/full/10.1080/13549839.2011.565464" target="_blank">a systems approach</a>.
<h2>Setting the goals of transformation</h2>
All cities are not the same. For this reason, <a href="https://www.science.org.au/supporting-science/future-earth-australia" target="_blank">Future Earth Australia</a>, a national initiative hosted by the <a href="https://www.science.org.au/about-us/academy" target="_blank">Australian Academy of Science</a>, has held <a href="https://www.science.org.au/supporting-science/future-earth-australia/projects/sustainable-australian-cities-and-communities" target="_blank">workshops around the country</a>. We have also launched a <a href="https://www.surveymonkey.com/r/6VW77MT" target="_blank">national online survey</a>.
The themes arising from the workshops offer valuable insights into how we can apply a systems approach to transforming Australian cities, and the regions and local areas that support our cities. Some key insights are:
<ul>
<li>density is important, but so is liveability</li>
<li>liveability has a different emphasis for each person, but includes green space, access to services, employment and transport</li>
<li>the consensus is that we must respond to climate change, through actions that both reduce the rate of change and adapt to it</li>
<li>people both in cities and outside them want explicit attention paid to how urban areas and their hinterlands interact and depend on one another</li>
<li>economic regeneration and notions of a circular economy are seen as essential elements of a “transformed” city.</li>
</ul>
Importantly, the nuances and variations between cities and regions were important to identity and individuality. Local, context-relevant innovation abounds, but is combined with much re-inventing of wheels. Our process has shown that linking local activity better with city-wide and even national coordination could greatly accelerate progress, while maintaining the sense of local identity. A majority of the world’s countries are actively taking a <a href="https://unhabitat.org/books/global-state-of-national-urban-policy/">national perspective</a> on their urban challenges.
The importance of local nuance is recognised in other parts of the world. In Europe, <a href="http://www.ecoacupuncture.com/transxperimentation" target="_blank">work is under way</a> to build better connections between small and medium-sized cities.
<h2>Wicked problems call for a systems approach</h2>
Urban transformation requires a systems approach to overcome well-documented challenges like urban expansion, decreasing housing affordability, biodiversity loss in peri-urban areas, spending hours in cars, and engaged governance across metropolitan areas. These challenges are tricky because they are caused by behaviours and settings that arise from entwined economic, social and environmental systems. Problems like this are wicked in nature.
A systems approach examines how communities, economics, culture, politics, infrastructure, design, planning, knowledge and technology interact and interweave to produce the places we live in. We must also recognise existing <a href="https://theconversation.com/can-your-actions-really-save-the-planet-planetary-accounting-has-the-answer-104005" target="_blank">planetary boundaries</a>.
Tackling these problems with a systems approach means ensuring that as we solve one of them we don’t create new problems in other areas. Or, even better, we solve multiple challenges at once. Responses must integrate bottom-up and top-down interventions across multiple sectors, consider time frames from today into the long term, and recognise the value in collaboratively forging the knowledge and actions we need.
This is why <a href="https://www.science.org.au/supporting-science/future-earth-australia" target="_blank">Future Earth Australia</a>, the Australian and Oceania network of <a href="http://www.futureearth.org/" target="_blank">Future Earth</a> based at the <a href="https://www.science.org.au/supporting-science/future-earth-australia" target="_blank">Australian Academy of Science</a>, invited urban thinkers and practitioners from around Australia to a <a href="https://www.science.org.au/supporting-science/future-earth-australia/projects/sustainable-australian-cities-and-communities" target="_blank">workshop in May 2018</a>. It was designed to <a href="https://www.science.org.au/files/userfiles/support/future-earth-australia/knowledge-for-sustainable-australian-cities-and-communities.pdf" target="_blank">work towards a consensus</a> on a ten-year plan for transformative knowledge for Australian cities. This workshop built on <a href="https://link.springer.com/article/10.1007/s13280-017-0934-6" target="_blank">recent urban systems scholarship</a>, which identified the need for multisectoral, collaborative and systemic thinking and collaborative design and governance.
We have implemented a series of processes to inform this decadal plan.
First, we interviewed senior decision-makers in government, industry and peak bodies.
We held nine workshops across the country. These involved over 350 participants, representing senior decision-makers in government, industry and peak bodies, community groups and academic researchers. The insights from the workshops have all been <a href="https://www.science.org.au/supporting-science/future-earth-australia/projects/sustainable-australian-cities-and-communities" target="_blank">published</a>.
And we have designed a <a href="https://www.surveymonkey.com/r/6VW77MT" target="_blank">survey that’s now open to anyone living in Australia</a>.
An independent <a href="https://aas.eventsair.com/urban-systems-transformation-sustainable-cities/reference-group" target="_blank">reference group</a> of urban experts from 21 research, policy and practice organisations around the country is overseeing these processes.
Our aim is to encourage all stakeholders to work together. The Future Earth platform can enable partnerships that harness these ideas and knowledge about the transformations needed to create sustainable, liveable cities.
We need better urban knowledge and the many cross-sectoral contributions to the Future Earth urban decadal plan have offered vital directions for future effort.<img src="https://counter.theconversation.com/content/119235/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important; text-shadow: none !important;">

In 2019, <a href="https://www.communitycouncil.com.au/content/australia-we-want-media-release-7-may-2019" target="_blank">The Australia We Want</a> report noted that at least half of Australian women do not feel safe walking alone at night. This is unsurprising given the <a href="https://www.plan.org.au/freetobe" target="_blank">prevalence of sexual harassment</a> and gender violence women manage when moving through cities every day. Women’s avoidance of areas of the city creates a <a href="https://theconversation.com/no-harm-done-sexual-entertainment-districts-make-the-city-a-more-threatening-place-for-women-81091" target="_blank">complex internal geography of exclusion zones</a> and “take extreme care” zones – all in the hope that this vigilance will keep them out of harm’s way.
Protecting women from the violence committed by some men is a priority. So too is recognising that most <a href="https://theconversation.com/gender-makes-a-world-of-difference-for-safety-on-public-transport-80313" target="_blank">cities are gender-blind and disregard women’s needs and experiences</a>.
We need to understand the patterns that exclude women from areas of cities and not defer to the usual responses – brighter lighting, more CCTV cameras and more authority figures. In fact, <a href="http://planfreetobe.org/">our research</a> into unsafe “hotspots” has found young women’s perceptions of urban safety do not correlate with the most brightly lit spaces.
We know that creating safer cities for women requires one fundamental shift: that we <a href="https://theconversation.com/to-design-safer-parks-for-women-city-planners-must-listen-to-their-stories-98317" target="_blank">listen to women’s voices</a>. We need to develop urban strategies and planning policies that draw on women’s experience and expertise as users of city spaces.
What does the research tell us?
<a href="https://www.plan.org.au/" target="_blank">Plan International</a>, the <a href="https://www.monash.edu/mada/research/labs/xyx-lab-monash-space-gender-communication-lab" target="_blank">Monash University XYX Lab</a> and <a href="https://www.arup.com/" target="_blank">ARUP</a> lighting researchers have pooled their expertise to drill down into the stories of young women and analyse the relationship between urban lighting and women’s perceptions of safety.
<a href="https://research.arup.io/story/cities-for-girls">The research </a>struck on some compelling correlations between light levels and unsafe places. Analysing over 80 of the most unsafe “hotspots” identified by women in Melbourne, the research found that high illuminance – or very bright and overlit spaces – does not correlate with young women’s perceptions of urban safety.
This is important information as planners often light spaces to a high <a href="https://www.standards.org.au/standards-catalogue/sa-snz/electrotechnology/lg-002/as-slash-nzs--1158-dot-4-colon-2015" target="_blank">“P” Category</a> (a measure used in urban place-making guidelines) of lighting. It’s assumed this will reduce the risk of crime and increase the feeling of safety.
But our research shows that designing lighting that is positive for women’s urban experience requires more nuance. The findings show that sites with higher light levels are more likely to be perceived as unsafe sites – the average light level across these sites was twice what was measured across safe sites. This is a finding with the potential to radically change a city’s approach to lighting for safety.
The analysis showed that consistent and layered lighting – where there are multiple light sources and where surfaces with different reflective values are taken into consideration – makes women feel most safe. This kind of lighting reduces the “floodlit effect”, the sharp drop-off of light beyond the path, and the potential for glare and contrast to blind and disorientate.
The emphasis on LED lights for their energy efficiency is unquestioned. But in urban lighting they are mostly a higher colour temperature such as 4000K “cool white” and above. This new research challenges the effects of this approach.
Instead of yellowish sodium lighting, women prefer a high-quality LED light that enables them to distinguish shapes and colours. 
ARUP’s research shows the human visual spectrum reacts better to warm light, and the data from young women showed how sensitive they are to cool white light with regard to feeling safe in cities. Spaces with warmer colour temperatures are perceived as safer places.
Looking deeper into the quality of light in our cities, the majority of bad areas had a very large range of colour rendering. The lowest colour rendering came from sodium luminaires that make everything look overly yellow. Women preferred a high-quality LED light that enabled them to distinguish shapes and colour, helping to create a sense of safety.
What does this mean for urban design?
More broadly, the research challenged the assumptions that urban lighting design relies on in general, and the effect it has on the character of our cities at night.
At present, illuminance (the measure of light falling on a surface, or Lux) is the only unit of measurement required to comply with the P Categories of the Australian Standards. Based on the results, it appears other metrics such as luminance (light bouncing off a surface and hitting the observer’s eye) should be considered too. This will ensure the context of material finishes and surface intensity is taken into account for how the eye perceives space.
Through research such as this, we have the knowledge, data and technology to engage women in trialling new ways of co-designing better outcomes for cities after dark. We can use considered urban design as a tool for positive change.

More lighting alone does not create safer cities: Nicole Kalms

GUEST OBSERVATION
The Greater Sydney Commission <a href="https://www.greater.sydney/metropolis-of-three-cities" target="_blank">has proposed</a> a 40-year vision of a metropolitan region formed of three “cities”: the Eastern “Harbour” City, the Central “River” City, and the Western “Parkland” City. The plan aims to create 30-minute cities, where the community has access to jobs and services in three largely self-contained but connected regions. Thus, Sydney would be polycentric.
<a href="https://images.theconversation.com/files/272465/original/file-20190503-103071-14wvrq1.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/272465/original/file-20190503-103071-14wvrq1.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt=""></a>
The Greater Sydney Commission’s Three Cities Plan. <a class="source" href="https://www.greater.sydney/metropolis-of-three-cities" target="_blank">Greater Sydney Commission</a>
A polycentric city has multiple centres of employment, economic or social activity. Local labour markets and residential zones minimise long commutes, create a sense of place and neighbourhood, and strengthen economic agglomeration as companies, services and industries benefit from being close to one another.
However, it is still unclear whether Sydney is actually moving towards such a structure. In our <a href="https://www.propertyobserver.com.au/https://journals.sagepub.com/doi/abs/10.1177/0042098019832517" target="_blank">recent work</a>, we developed new ways of measuring polycentricity. We applied these to <a href="https://www.abs.gov.au/ausstats/abs@.nsf/Lookup/by%20Subject/2071.0.55.001%7E2016%7EMain%20Features%7EJourney%20to%20Work%20to%20Place%20of%20Work%7E60" target="_blank">Journey to Work data</a> from the 2016 Census to test how consistent the current centricity patterns of Greater Sydney are with the proposed plan.
How do you measure polycentricity?
Traditionally, employment densities are used as a measure of polycentricity. If the density of jobs in a location is higher than the average density for the entire region, then it is a centre.
However, this simple measure misses a key notion that makes cities what they are: network flows and spatial interactions. People “flow” from one place to another. Employment centres “attract” flows, and residential areas “produce” flows. Thus, a city is a collection of locations that interact dynamically, connected by daily commuting flows.
We proposed a set of new metrics to capture this idea of flows. We defined the net inflow of people to a location as the total number coming to this location to work minus the total number going from this location to work elsewhere. If the net inflows are positive, this place is a centre.
The chart below illustrates the idea. The base arc on the circle shows the number of people “flowing” out of a location to another location. The connecting arcs are coloured black if the net inflows into the focus regions (a), (b) or (c) are positive.
<a href="https://images.theconversation.com/files/272469/original/file-20190503-103053-1y6xdsk.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/272469/original/file-20190503-103053-1y6xdsk.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt=""></a>
Testing polycentricity via net inflows: (a) Sydney City and Inner South (Sydney CBD), (b) Parramatta, (c) Eastern Suburbs. Source: The authors
Sydney CBD clearly emerges as a global centre for the whole region. Parramatta is a regional centre. Other locations such as the Eastern Suburbs are not centres at all.
The net inflow to a location can be divided by the total number of trips in the system, so inflow values are scaled from 0 to 1 using a standard statistical procedure. The higher the value, the higher the centre’s rank in the urban system. Here, a score of 1 means the centre is an absolute: all the trips in the system are a net inflow into the centre.
This gives us a trip-based centricity measure. And based on the area of the location, we can calculate a density-based centricity measure.
The maps below show trip-and-density-based measures – (a) and (b) respectively – for Greater Sydney at the Statistical Area Level 2 (representing a community that interacts together socially and economically).
Note the dominant role of the Sydney CBD. The other centres emerge as weak centres. Also, many of the second-order centres are very close to the CBD.

The concept of accessibility
Counting the net inflow into a location may provide us with information about general centricity. However, it still does not tell us how easy or difficult it is for people to actually get to jobs. This brings us to the idea of accessibility.
Walter Hansen <a href="https://www.propertyobserver.com.au/https://www.tandfonline.com/doi/abs/10.1080/01944365908978307?journalCode=rjpa19" target="_blank">defined accessibility</a> as “the spatial distribution of activities about a point, adjusted for the ability and the desire of people … to overcome spatial separation”. More practically speaking, a location is accessible if it can be reached within a set time (say 30 minutes) from another location.
We counted the net accessibility of a location by counting the number of jobs minus the number of workers (labour) that could be accessed from a particular location (SA2) in Sydney within 30 minutes. We counted travel time both by car and by public transport during a usual weekday peak hour (Wednesday 8am). Similar to the trip and density measures, accessibility centricities can also be scaled as values between 0 and 1. This allows us to compare across the four measures.
In the maps above, (c) and (d) show the transit and auto-based accessibility centricities based on accessibility for public transport and vehicles. Sydney CBD is highly accessible. The second-order centres show much weaker accessibility.
Takeaways for urban policy and the three-cities plan
The chart below shows the top-ranked centre, Sydney CBD (Level 1 centre), and the lower-ranked subcentres (Levels 2 and 3) emerging from our analysis.
<a href="https://images.theconversation.com/files/274555/original/file-20190515-60570-9791ct.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/274555/original/file-20190515-60570-9791ct.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt=""></a>

Accessibility planning should guide the design of a polycentric city
The design of polycentric Sydney should be guided by accessibility, the locations of jobs and homes, and subregional labour market organisation.
In short, the region should give priority to making jobs accessible by locating new jobs in emerging centres, instead of a mobility-focused system that takes people to jobs.
Reduce spatial mismatches between jobs and homes
Our results show that Sydney, paradoxically, remains strongly monocentric and strongly dispersed at the same time. The Sydney CBD accounts for 15% of jobs in the region, with the remaining 85% of jobs scattered around in weaker second-order centres and non-centres. Positive correlations exist between percentage of employed workers, trip-based centricity and the subcentre ranks.
But we see significant disparities between these ranks and accessibility centricities. This shows the spatial mismatches for commute lengths in the system.
A subcentre with high trip-centricity, employing a high percentage of workers, but relatively lower auto- and transit-based accessibility centricity, implies that even though a significant percentage of the population comes to this location to work, access to jobs at this centre within 30 minutes is low.
A policy response would be to increase the accessibility of jobs from this location, as it already serves as a centre. This situation is particularly clear in the cases of Parramatta-Rosehill and Macquarie Park-Marsfield. Penrith and Liverpool too have extremely weak accessibility centricity.
Polycentric cities should promote spatial justice
As cities grow in size, commute lengths increase if the labour market for the entire metropolitan region is integrated. Commute lengths will stabilise if a city has a clear polycentric or modular structure.
In the case of Sydney, <a href="https://theconversation.com/what-did-the-rich-man-say-to-the-poor-man-why-spatial-inequality-in-australia-is-no-joke-73841" target="_blank">spatial equity</a> has always been a concern. However, <a href="https://theconversation.com/our-big-cities-are-engines-of-inequality-so-how-do-we-fix-that-69775" target="_blank">inter-city comparisons</a> show city size has a strong bearing on its equity and efficiency.
Our results show it’s increasingly important for larger cities to introduce a framework of subregional labour markets as part of the polycentricity agenda. Enabling shorter commutes for workers will improve spatial equity as well as efficiencies.<img src="https://counter.theconversation.com/content/115847/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important; text-shadow: none !important;">

EXPERT OBSERVER
The new Minister for Planning and Public Spaces, Rob Stokes, must kick start Sydney’s falling housing supply as his first priority.
Rob Stokes is a good choice as NSW Planning Minister as he clearly understands the portfolio and is a good advocate for quality urban growth.
Rob has previously been Planning Minister but the portfolio has become much more complex and is even more significant for the state’s economy than when he left the portfolio. Housing approvals have collapsed in Sydney, as have housing pre sales, which will lead to a big drop in the supply chain of new homes over the next few years.
Part of the reason for the big drop in approvals over the last year has been the very negative rhetoric about over development across Sydney that has even included terrace houses as being too dense for suburban streets. The Ryde council area has put all new planning proposals on hold, and 50 councils have been given a moratorium on allowing town houses and terrace houses in their areas.
There is also significant confusion about the role of the Greater Sydney Commission (GSC) with its planning Assurance Reviews, related to the role of the Department of Planning particularly with policy and strategic planning issues. The Minister will need to clarify the roles of these two organisations.
When Premier Berejiklian first took on the role of Premier she stated her first priority was to increase housing supply, but the opposite is now occurring with a dramatic slowdown in supply. It is essential that the State Government must make the increase of housing supply its first priority.
Compounding the slowdown in housing approvals is the increasing cost for infrastructure levies; with the government’s cap now removed and confusion over policies for affordable housing, and the use of old industrial land where the GSC seems to have a different position to the Department of Planning.
The Urban Taskforce believes that Minister Stokes must instigate a Housing Supply Summit soon, so that all parties can understand what is likely to happen over coming years if no policy changes are made. It will be important to involve NSW Treasury in the Summit, as stamp duty levies will dramatically reduce NSW Government income unless the industry is stimulated.

<div class="column">
We also acknowledge the appointment of Andrew Constance in the important role of Minister for Transport and Roads, as this infrastructure is the critical determinant of where new growth should be located.
Clearly the Treasurer, Dominic Perrottet, will have a critical input into the housing and property industry, as any slowdown will have a negative impact on the state’s economic performance. We believe the Treasurer will need to get his Productivity Commissioner and Chief Economist to take a critical look at the housing industry.
The Urban Taskforce is keen for the new Minister for Property and Housing, to continue the Communities Plus program of renewing social housing estates across Sydney.
A major priority is to ensure that the Minister for Planning has up to date information on housing approvals and commencements as the Department of Planning’s Housing Monitor has not been updated since October 2018. It is essential that transparent information on housing supply is available for all stakeholders.
CHRIS JOHNSON is the Urban Taskforce CEO.

GUEST OBSERVATION
Urban nature has a critical role to play in the <a href="https://theconversation.com/higher-density-cities-need-greening-to-stay-healthy-and-liveable-75840" target="_blank">future liveability of cities</a>. An emerging body of research reveals that bringing nature back into our cities can deliver a truly impressive array of benefits, ranging from <a href="https://theconversation.com/why-a-walk-in-the-woods-really-does-help-your-body-and-your-soul-53227" target="_blank">health and well-being</a> to <a href="https://theconversation.com/if-planners-understand-its-cool-to-green-cities-whats-stopping-them-55753" target="_blank">climate change adaptation and mitigation</a>. Aside from benefits for people, cities are often hotspots for threatened species and are justifiable locations for serious investment in nature conservation for its own sake.
Australian cities are home to, on average, <a href="https://www.conservationmagazine.org/2016/01/threatened-species-live-in-every-australian-city/" target="_blank">three times as many threatened species per unit area as rural environments</a>. Yet this also means urbanisation remains one of the most destructive processes for biodiversity.
Despite government commitments to green urban areas, vegetation cover in cities continues to decline. A recent report found that <a href="https://theconversation.com/were-investing-heavily-in-urban-greening-so-how-are-our-cities-doing-83354" target="_blank">greening efforts of most of our metropolitan local governments are actually going backwards</a>.
Current urban planning approaches typically consider biodiversity a constraint – a “problem” to be dealt with. At best, biodiversity in urban areas is “<a href="https://www.iucn.org/theme/business-and-biodiversity/our-work/business-approaches-and-tools/biodiversity-offsets" target="_blank">offset</a>”, often far from the site of impact.
This is a poor solution because it fails to provide nature in the places where people can benefit most from interacting with it. It also delivers <a href="https://theconversation.com/the-plan-to-protect-wildlife-displaced-by-the-hume-highway-has-failed-78087" target="_blank">questionable ecological outcomes</a>.
Building nature into the urban fabric
A new approach to urban design is needed. This would treat biodiversity as an opportunity and a valued resource to be preserved and maximised at all stages of planning and design.
In contrast to traditional approaches to conserving urban biodiversity, biodiversity-sensitive urban design (BSUD) aims to create urban environments that make a positive onsite contribution to biodiversity. This involves careful planning and innovative design and architecture. BSUD seeks to build nature into the urban fabric by linking urban planning and design to the basic needs and survival of native plants and animals.
<a href="https://images.theconversation.com/files/240750/original/file-20181016-165888-bm8qxg.jpeg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/240750/original/file-20181016-165888-bm8qxg.jpeg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=237&amp;fit=clip" alt=""></a>
Figure 1. Steps in the biodiversity sensitive urban design (BSUD) approach (click to enlarge). Author provided
BSUD draws on ecological theory and understanding to apply five simple principles to urban design:
<ol>
<li>protect and create habitat</li>
<li>help species disperse</li>
<li>minimise anthropogenic threats</li>
<li>promote ecological processes</li>
<li>encourage positive human-nature interactions.</li>
</ol>
These principles are designed to address the biggest impacts of urbanisation on biodiversity. They can be applied at any scale, from individual houses (see Figure 2) to precinct-scale developments.
<a href="https://images.theconversation.com/files/240903/original/file-20181016-165903-tqp2fp.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/240903/original/file-20181016-165903-tqp2fp.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt=""></a>
Figure 2. BUSD principles applied at the scale of an individual house. Author provided
BSUD progresses in a series of steps (see Figure 1), that urban planners and developers can use to achieve a net positive outcome for biodiversity from any development.
BSUD encourages biodiversity goals to be set early in the planning process, alongside social and economic targets, before stepping users through a transparent process for achieving those goals. By explicitly stating biodiversity goals (eg. enhancing the survival of species X) and how they will be measured (eg. probability of persistence), BSUD enables decision makers to make transparent decisions about alternative, testable urban designs, justified by sound science.

What does a BSUD city look, feel and sound like?
Biodiversity sensitive urban design represents a fundamentally different approach to conserving urban biodiversity. This is because it seeks to incorporate biodiversity into the built form, rather than restricting it to fragmented remnant habitats. In this way, it can deliver biodiversity benefits in environments not traditionally considered to be of ecological value.
It will also deliver significant co-benefits for cities and their residents. <a href="http://www.abs.gov.au/ausstats/abs@.nsf/lookup/Media%20Release10" target="_blank">Two-thirds of Australians</a> now live in our capital cities. BSUD can add value to the remarkable range of benefits urban greening provides and help to deliver greener, cleaner and cooler cities, in which residents live longer and are less stressed and more productive.
BSUD promotes human-nature interactions and nature stewardship among city residents. It does this through <a href="https://www.archdaily.com/877602/jan-gehl-in-the-last-50-years-architects-have-forgotten-what-a-good-human-scale-is" target="_blank">human-scale urban design</a> such as mid-rise, courtyard-focused buildings and wide boulevard streetscapes. When compared to high-rise apartments or urban sprawl, this scale of development has been shown to deliver better liveability outcomes such as active, walkable streetscapes.
<a href="https://images.theconversation.com/files/240908/original/file-20181016-165905-lxdpiu.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/240908/original/file-20181016-165905-lxdpiu.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt=""></a>
Mid-rise, courtyard-focused buildings and wide boulevard streetscapes created through a biodiversity sensitive urban design approach. Graphical representation developed by authors in collaboration with M. Baracco, C. Horwill and J. Ware, RMIT School of Architecture and Design, Author provided
By recognising and enhancing Australia’s unique biodiversity and enriching residents’ experiences with nature, we think BSUD will be important for creating a sense of place and care for Australia’s cities. BSUD can also connect urban residents with Indigenous history and culture by engaging Indigenous Australians in the planning, design, implementation and governance of urban renaturing.
What needs to change to achieve this vision?
While the motivations for embracing this approach are compelling, the pathways to achieving this vision are not always straightforward.
Without careful protection of remaining natural assets, from remnant patches of vegetation to single trees, vegetation in cities can easily suffer “death by 1,000 cuts”. Planning reform is required to move away from offsetting and remove obstacles to innovation in onsite biodiversity protection and enhancement.
In addition, real or perceived conflicts between biodiversity and other socio-ecological concerns, such as bushfire and safety, <a href="https://theconversation.com/smart-city-planning-can-preserve-old-trees-and-the-wildlife-that-needs-them-98632" target="_blank">must be carefully managed</a>. Industry-based schemes such as the Green Building Council of Australia’s <a href="https://new.gbca.org.au/green-star/rating-system/" target="_blank">Green Star system</a> could add incentive for developers through BSUD certification.
Importantly, while BSUD is generating much interest, working examples are urgently required to build an evidence base for the benefits of this new approach.<img src="https://counter.theconversation.com/content/102849/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important; text-shadow: none !important;">
