One of North Sydney's best-known commercial buildings could become hundreds of new homes, with insurance giant Zurich Australia lodging a State Significant Development Application (SSDA) to transform 5 Blue Street into a mixed-use residential development above North Sydney Station.

Rather than demolishing the existing building and starting again, Zurich is proposing an adaptive reuse project that would convert the landmark office building into a 15-level residential development delivering 62 apartments, 86 affordable co-living dwellings, activated retail and significant upgrades to the Blue Street Plaza.

The proposal reflects a growing trend of commercial property owners repositioning ageing office assets into residential housing as Sydney grapples with housing supply shortages and changing workplace demand.

<img alt="Zurich" data-entity-type="file" data-entity-uuid="0bba7d12-06dc-4375-aad7-238c94b21ac5" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-07-22%20at%2010.42.05%E2%80%AFAM.png?VersionId=NJl5oLAEBDGuPmY3RnyliKODjMc8lvRh" />

Located directly above North Sydney Metro and train station, the 3,051 sqm site occupies one of the most strategically positioned parcels of land on Sydney's Lower North Shore.

Designed by fjcstudio, the proposal seeks to retain and adapt much of the existing structure while creating a contemporary residential address that better connects with the public domain surrounding North Sydney Station.

The application proposes two basement levels, ground floor retail, affordable co-living accommodation across the podium levels, and apartments above, while preserving and enhancing the publicly accessible Blue Street Plaza.

Rather than pursuing maximum apartment numbers, Zurich has opted for a housing mix heavily weighted towards larger owner-occupier residences.

The proposal includes 62 build-to-sell apartments comprising 12 one-bedroom, 19 two-bedroom, 29 three-bedroom apartments and two premium penthouses. It also incorporates 86 affordable co-living dwellings, which would be managed in perpetuity by a Community Housing Provider.

That balance between traditional apartments and affordable housing reflects the NSW Government's push to increase housing diversity around major transport infrastructure.

The proposal has been lodged concurrently with a rezoning application, with Zurich arguing the site is ideally positioned to support additional housing given its immediate proximity to public transport, employment and services.

"The proposal aims to respond to the housing challenges facing Sydney through the delivery of diverse housing types in a highly accessible location," the design report by fjcstudio states. It also seeks to improve pedestrian amenity through upgrades to Blue Street Plaza while creating a high-performing residential building that responds to the surrounding context.

<img alt="Zurich" data-entity-type="file" data-entity-uuid="36082e15-c636-4481-bb68-5a5f6443fe39" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-07-22%20at%2010.41.36%E2%80%AFAM.png?VersionId=5P6VD.fvmqjQfIG3TWWMRXxQWiQBjeFB" />

Rather than replacing the commercial building, fjcstudio has developed a design that works with the existing structural framework above the rail corridor, an approach that significantly reduces demolition while allowing the site to be repositioned as a mixed-use residential precinct.

The existing structural constraints have informed much of the building's design, including its relationship with Blue Street and surrounding public spaces.

The building has been designed as a slender tower rising above a clearly defined podium, with vertically expressed façades intended to reduce the perceived bulk while reinforcing North Sydney's emerging skyline.

According to fjcstudio, the architectural language responds directly to the surrounding commercial towers while maintaining a finer grain expression more closely aligned with the neighbouring Lavender Bay streetscape.

The tower incorporates articulated façade elements, landscaped podium edges and recessed upper levels to soften its appearance and improve pedestrian amenity below.

A significant component of the proposal is the revitalisation of Blue Street Plaza.

The existing public space has long served as one of the primary pedestrian connections between North Sydney Station, Greenwood Plaza and Blue Street, yet its role is expected to become even more important following the opening of Sydney Metro.

Zurich's proposal seeks to strengthen that role by improving landscaping, introducing new retail frontages, enhancing pedestrian permeability and creating more active edges throughout the day and evening.

Ground floor retail would wrap the plaza, while separate residential and co-living entries have been designed to improve wayfinding without reducing street activation.

Landscape design has been integrated throughout the podium and public realm, softening what is currently one of the most heavily urbanised parts of North Sydney.

&nbsp;

&nbsp;

fjcstudio has carefully oriented apartments towards Sydney Harbour and the CBD while using privacy blades and articulated façades to minimise overlooking between neighbouring buildings.

Large framed openings along the western elevation maximise harbour outlooks, while the eastern apartments have been angled towards the south-east to improve privacy from neighbouring development.

The project forms part of the continuing transformation of North Sydney from a predominantly commercial CBD into a genuine mixed-use city centre.

Since the completion of Victoria Cross Metro Station, developers have increasingly shifted their attention towards residential projects capable of leveraging the area's unparalleled transport connectivity.

&nbsp;

FiveX recently lodged plans for a 61-storey, 490-apartment tower that would become one of the tallest residential buildings in North Sydney if approved.

Aqualand continues to expand its Lower North Shore presence following the completion of AURA on Walker Street and its recent St Leonards and Roseville proposals.

Developers are also progressing projects throughout Walker Street, Miller Street and the Victoria Cross precinct as demand for well-located owner-occupier apartments continues to strengthen.

Busy developer Aqualand Prestige has formally taken the next step in its expansion across Sydney's Lower North Shore, lodging a State Significant Development Application (SSDA) for its long-held Archer Street site in Chatswood.

The application covers <a href="https://www.apartments.com.au/new-apartments/51-55-archer-street-chatswood-nsw-2067">51-55 Archer Street</a>, a 1,767 sqm amalgamated site on the eastern edge of the Chatswood CBD, where the developer is seeking approval for a 45-level mixed-use tower delivering 114 apartments, including a significant affordable housing component, alongside retail, commercial space and six basement levels of parking.

The SSDA marks the latest milestone for a project Aqualand has been quietly progressing over the past two years. The developer first secured the site for its Aqualand Prestige platform before undertaking an alternative design excellence process with PTW Architects, ultimately avoiding a formal design competition through the Housing Delivery Authority pathway.

The proposal has evolved considerably from Aqualand's original concept. The revised scheme has been designed around larger owner-occupier product, with an unusually high proportion of three and four-bedroom apartments, targeting the more affluent buyer profile, and downsizer, emerging across the North Shore.

<img alt="Archer St" data-entity-type="file" data-entity-uuid="0171204c-5811-41b5-9b09-2335d1b7c3d0" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-07-22%20at%208.52.48%E2%80%AFAM.png?VersionId=6YTuxfq.puZo7k2wbfgemcO5K3QfXYGQ" />

The 114-apartment mix comprises six studios, 27 one-bedroom apartments, 18 two-bedroom apartments, 50 three-bedroom residences and 13 four-bedroom homes. A quarter of the building will be dedicated to affordable housing, well above the mandated 15 per cent&nbsp;

PTW has structured the building vertically, with affordable housing across levels one to six, premium apartments through levels seven to 31, duplex skyhomes on klevels 32 to 43, a penthouse on level 44, and a rooftop plant level above. Six basement levels will provide resident parking and servicing.

The tower is proposed to reach approximately 154 metres, placing it among a growing collection of residential high-rises transforming Chatswood's skyline.

Rather than competing purely on height, PTW says the design has been driven by creating a slimmer tower capable of delivering significantly larger apartments.

"The primary objective of this project was to create a distinctive building that stands out from the recently approved or built structures in the Chatswood area," the design report states, noting the structural efficiency allows greater investment into apartment quality and resident amenity.

Residents would have access to more than 450 sqm of communal open space including landscaped gardens, swimming pool, rooftop entertaining areas, fitness spaces, community gardens, children's play areas and barbecue facilities.

A major focus of the design has been the public domain.

The ground plane has been opened up through landscaped terraces inspired by Willoughby's sandstone ridges, with native planting, public seating, artwork, retail activation and a series of gathering spaces intended to soften what has traditionally been a hard commercial streetscape.

The landscape strategy references Blue Gum forests once common throughout the area, while incorporating Indigenous storytelling, public art and lighting installations to strengthen the connection to Country.

Chatswood has been one of Sydney's busiest apartment markets over the past 12 months, with a steady pipeline of both new project launches and fresh development applications.

Hyecorp recently launched Celine, a 122-apartment development just along Archer Street, while Changfa and Huirong Group are progressing The Anderson, an 84-apartment project on Anderson Street.

Develotek recently secured approval for a 101-apartment tower on Pacific Highway, while Tian An LFD received the green light for Hammond Greens, its apartment development on the edge of the Chatswood Bowling Club.

Commercial property developer FiveX is also making its move into the residential market. Last month it lodged plans for a 61-storey tower with 490 apartments, which, if approved, would become one of the tallest residential buildings in Chatswood.

Aqualand is also expanding its development pipeline following the launch of its luxury residential brand, Aqualand Prestige. The developer has delivered a string of high-end apartment projects across Sydney's affluent suburbs over the past decade, most recently AURA by Aqualand on Walker Street in North Sydney.

[smartcode_project:default project_id=30959 project_image_fid=292863]

It has since quietly assembled its next wave of projects.

Earlier this year Aqualand launched Boronia in Roseville, a boutique 111-apartment development on Larkin Street. The project is one of the first significant apartment developments to launch in the suburb ahead of what is expected to become one of Sydney's most active new housing precincts under the NSW Government's Low and Mid-Rise Housing reforms, which allow greater density around train stations.

[smartcode_project:default project_id=152095 project_image_fid=373685]

The developer has also lodged plans for a two-tower, 413-apartment development on Herbert Street in nearby St Leonards, further strengthening its presence across the Lower North Shore.

Beyond that, Aqualand remains behind the final stage of Barangaroo, where plans will deliver a five-hectare mixed-use precinct comprising new homes, retail, hospitality and community facilities, alongside a new Metro entrance and more than two hectares of public open space, completing the Barangaroo precinct.

Mass timber is becoming an increasingly popular construction material in apartment developments, but Adelaide developer <a href="https://www.apartments.com.au/developers/otello">Otello</a> is taking the approach a step further.

At its new <a href="https://www.apartments.com.au/new-apartments/flowe-bowden-18-gibson-street-bowden-sa-5007">Flowe Bowden</a> development, the exposed cross-laminated timber (CLT) structure isn't just about reducing the building's environmental footprint. It also forms the foundation of a broader wellness strategy, influencing everything from indoor air quality and natural materials to the way residents move through and experience the building.

The 115-apartment mixed-use development, designed by Melbourne-based architecture practice Fieldwork, will occupy a prominent island site opposite Bowden Village Reserve, combining one, two and three-bedroom apartments with retail and a dedicated wellness destination.

[smartcode_project:default project_id=152022 project_image_fid=375528]

Wellness isn't confined to a gym or shared resident facility at Flowe. Instead, Fieldwork embedded the concept into the building itself.

The development has been split into two residential wings connected by a naturally ventilated central breezeway, replacing traditional enclosed corridors with open-air walkways that improve natural light, encourage cross ventilation and create more opportunities for neighbourly interaction.

"Rather than treating wellness as something that only happens on the ground floor, our response integrates it throughout the building, which led us to ask what it really means to design a healthy building," Fieldwork Director Quino Holland said.

[smartcode_project:default project_id=152022 project_image_fid=375531]

The building's architecture also reflects Bowden's industrial heritage. The lower podium references the area's historic brick and sandstone buildings, while the upper levels transition to exposed CLT, allowing the timber structure to become a defining feature throughout the apartments and shared spaces.

The use of mass timber sits alongside a range of sustainability initiatives, including a fully electric, gas-free design, rooftop solar and a targeted 5 Star Green Star rating.

[smartcode_project:default project_id=152022 project_image_fid=375524]

Inside the residences, the focus remains on natural, durable materials. Blackbutt engineered timber flooring, exposed CLT ceilings, porcelain surfaces and warm timber joinery create a calming interior palette, while low-VOC finishes and responsibly sourced materials have been selected to improve indoor air quality.

Kitchens have been designed as the centrepiece of each apartment, featuring porcelain island benchtops, timber-look cabinetry and brushed steel tapware, with layouts that maximise natural light and ventilation.

[smartcode_project:default project_id=152022 project_image_fid=375530]

The more traditional interpretation of wellness comes in the form of Level Eleven, a two-storey wellness club spanning the ground floor, mezzanine and first floor.

The facility will include a gym, yoga and reformer Pilates studios, Finnish and infrared saunas, magnesium hot and cold plunge pools, and dedicated recovery spaces. Unlike many residential wellness facilities, Level Eleven will also operate commercially, allowing the broader Bowden community to access the venue while giving residents exclusive membership benefits.

The ground floor has also been designed around everyday living. A café overlooking Bowden Village Reserve will activate the street frontage, while a bike workshop with tool storage, co-working space and dog wash has been incorporated to support daily routines and encourage interaction between residents.

"Flowe brings together my two biggest passions, creating places and creating healthier lives," Otello founder Daniel Harris said.

"We wanted to create something Adelaide hasn't seen before, a genuinely healthy building, where the way you live is lifted without even trying."

Flowe is positioned directly opposite Bowden Village Reserve and within walking distance of Bowden Railway Station and the Adelaide Entertainment Centre, placing future residents just minutes from the Adelaide CBD while remaining connected to one of the city's most established urban renewal precincts.

Not all apartment amenities are immediately visible.

Swimming pools, gyms, rooftop terraces and residents' lounges have long featured on buyers' wishlists, but as the way Australians live has changed, so too have the features that make apartment living more convenient.

Increasingly, buyers are placing value on the practical aspects of day-to-day life. Fast internet, EV charging, secure bike storage, flexible workspaces and parcel management are becoming just as relevant as lifestyle amenities, reflecting changing habits and expectations.

Online shopping has been one of the biggest drivers of that shift.

Australians spent a record $82.6 billion shopping online in 2025, with almost one in every four retail dollars now spent digitally, making parcel deliveries a routine part of everyday life rather than an occasional convenience.

For apartment residents, however, receiving those deliveries isn't always straightforward.

Without someone home to accept a parcel, deliveries can be redirected to a nearby Post Office, left in building foyers or common areas, or require building management to temporarily store packages. As apartment living continues to grow across Australia's cities, parcel management has become an increasingly important consideration for both residents and developers.

Australia Post's Parcel Locker network is one response to that shift.

<iframe allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" allowfullscreen="" frameborder="0" height="315" referrerpolicy="strict-origin-when-cross-origin" src="https://www.youtube.com/embed/KPZ9j5FRdsQ?si=Qztc1dNP3ZvEIUhb" title="YouTube video player" width="560"></iframe>

Rather than relying on home delivery, eligible parcels can be directed to a nominated Parcel Locker, where they're securely stored until collected. Once a parcel arrives, residents receive a notification through the AusPost app or SMS and can retrieve it using a one-time code or QR code at a time that suits them.

The network has expanded to more than 1,500 locations nationwide, with Parcel Lockers positioned at Post Offices, shopping centres, supermarkets, transport hubs and, increasingly, within or alongside residential developments.

That growing presence reflects a broader change in how apartment buildings are being planned.

Developers are increasingly considering the operational side of apartment living alongside traditional lifestyle amenities. Just as secure mailrooms, bicycle storage and EV charging have become more common inclusions, parcel management is emerging as another feature that supports everyday convenience.

It also helps preserve the arrival experience within a building. Carefully designed lobbies and communal spaces can quickly become cluttered when deliveries accumulate, while secure parcel solutions reduce the likelihood of missed deliveries or parcels being left unattended.

For buyers comparing apartments, these everyday details are becoming part of the decision-making process.

Location, floorplans and finishes remain fundamental, but the features that simplify daily life are carrying greater weight than they once did. As online shopping continues to shape consumer behaviour, secure parcel delivery is increasingly becoming another amenity worth looking for.

Parcel delivery is joining the apartment amenity checklist

Inca Property Group has lodged a State Significant Development Application (SSDA) for Dawn, a 53-apartment oceanfront development overlooking Mona Vale Beach.

The proposal, at 35-39 Darley Street East, would replace an existing 18-apartment strata building with a new owner-occupier-focused development comprising 53 two and three-bedroom apartments, including nine affordable built-to-rent residences delivered under the State's infill affordable housing scheme.

Positioned on a 2,679 sqm elevated site around 280 metres from Mona Vale Beach, the development has been designed to maximise panoramic ocean views while responding to the site's sloping topography.

<a href="https://www.apartments.com.au/developers/inca-property-group">Inca Property Group</a> Managing Director Josh Thompson said the State Significant pathway provided greater certainty for projects of this scale.

"This State Significant pathway gives the team real certainty to progress <a href="https://www.apartments.com.au/new-apartments/dawn-35-39-darley-street-east-mona-vale-nsw-2103">Dawn</a> through to completion," Thompson said.

"It allows us to acquire a one-off site, design it carefully and deliver the right offering for the suburb, assessed by the NSW Government's planning department."

The project is one of the first developments in the area to be assessed under the NSW Government's Low and Mid-Rise Housing policy, with the site sitting on the edge of the policy's designated inner area.

The proposal includes three basement levels providing 124 car spaces, alongside a range of resident amenities including a swimming pool, gym, sauna, wellness facilities and private plunge pools for selected ground-floor and penthouse apartments.

<img alt="Dawn" data-entity-type="file" data-entity-uuid="fc1a1daf-0ce4-4f12-9076-b1fa553c7a91" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-07-21%20at%208.42.11%E2%80%AFAM.png?VersionId=4GZ9h.gpNkTljbxyAET8Jfhv51XUamDm" />

Thompson said Dawn had been designed specifically for owner-occupiers and downsizers, a buyer profile that has driven demand across Inca's recent Upper North Shore developments.

"The majority of buyers in our recent North Shore projects have been downsizers, and we are learning exactly what this market is looking for. Beyond the location itself, we have included resort-style amenities to deliver a genuine lifestyle offering," Thompson said.

Located within walking distance of Mona Vale Beach, the town centre, Mona Vale Golf Club and the Royal Motor Yacht Club, Dawn represents Inca's first Northern Beaches project following the sell-out of Tara on Park in Waitara and Ellis Residences, currently under construction in St Ives.

Construction will be undertaken by Inca's in-house construction arm, GOP Constructions.

Dawn is the latest major apartment proposal for Mona Vale, with the suburb emerging as one of the key beneficiaries of the NSW Government's new Low and Mid-Rise Housing policy.

New developer One Living, led by industry veteran Joseph Scuderi, recently secured a site on Mona Vale Road, on the border of Mona Vale and Pymble, where it is planning around 140 apartments.

IPM is also planning its third project in Mona Vale, significantly increasing the scale of its previous developments with an 82-apartment proposal at <a href="https://www.apartments.com.au/new-apartments/159-167-darley-street-west-mona-vale-nsw-2103">159-167 Darley Street West</a>, opposite Bayview Golf Course and less than 800 metres from Mona Vale town centre.

Housing Design

GUEST OBSERVATION
Australians need better solutions for coping with the warmer climate of the future (and present). 
Australian houses use <a href="http://www.lowcarbonlivingcrc.com.au/resources/crc-publications/crclcl-project-reports/rp1017e-validating-and-improving-basix-energy" target="_blank">significantly more electricity</a> to stay warm or cool than estimated during the design stage.
To design a new house in Australia, the building needs to meet the national construction code. One way to do this is by using software to simulate the building’s thermal efficiency, to see if it meets the minimum requirements of the national house energy scheme. The scheme divides Australia geographically into 69 different climate zones and requires new houses to be thermally appropriate for their environment.
Unfortunately, this software does not properly take into account our warming weather. Our <a href="http://www.lowcarbonlivingcrc.com.au/resources/crc-publications/rp1041-improving-thermal-performance-dwellings-carbon-positive-and" target="_blank">recent report</a> found the climate assumptions used by the government drastically underestimate the length and heat of summers in the near future.
In fact, buildings that perform best for heat waves predicted by 2030 are actually banned by the government’s building code. We urgently need to update our building codes to cope with our changing climate.
Understand the future local climate
We took Richmond in New South Wales as an example to understand the effect a changing climate might have on building performance. By taking predictions from <a href="http://www.exemplary.com.au/download/CSIRO%20Future%20climate%20data%20100%20solar%20sites%20-%20Exemplary%20-%20Final.pdf" target="_blank">CSIRO’s medium greenhouse gas emissions scenario</a>, we analysed Richmond’s likely weather for every week of 2030.
The future outlook, shown below, is strikingly different from the <a href="http://www.nathers.gov.au/nathers-accredited-software/nathers-climate-zones-and-weather-files" target="_blank">weather files</a> used to determine whether houses meet the minimum thermal performance requirement of the National Construction Code. In 2030, Richmond will experience a warm period almost four times longer than predicted by the official weather file.
<a href="https://images.theconversation.com/files/283169/original/file-20190708-51312-1i18f0d.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/283169/original/file-20190708-51312-1i18f0d.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt=""></a>
Author provided
Design for the future
Based on the future climate scenario, the design strategy for buildings in Richmond should focus on well shaded and insulated buildings to avoid any heat gain in the warm period, but should also harness sunlight to warm up the indoors in the cool period.
The warm period will last from December to March, when keeping the house cool is the priority. Passive solar heating, such as northern windows and well-insulated walls, floor and ceilings, are important during the May to September cool months, while direct ventilation is largely all that’s needed during the mostly comfortable April and October to November.
To test how houses will perform in a hotter future, we modelled a house in Richmond using AccuRate software. We found a design and construction solution that performed well (achieving 7.6 stars out of 10) for the 2030 scenario failed to meet a <a href="https://www.basix.nsw.gov.au/iframe/images/BASIX_Thermal_Comfort_Protocol_July17_rev1_Nov2017.pdf" target="_blank">heating threshold</a> that is legally required in NSW. In effect, the house that makes the most sense for the immediate future, could not be built.
These thresholds for heating and cooling are based on assumptions that are out of step with current conditions, let alone the future. Between 2016 and 2018 Richmond’s annual average temperature was 17.8℃, whereas the <a href="http://www.lowcarbonlivingcrc.com.au/resources/crc-publications/rp1041-improving-thermal-performance-dwellings-carbon-positive-and" target="_blank">NatHERS weather file</a> assumes it to be 16.7℃. This difference is set to increase.
In a 2019 amendment, the National Construction Code adopted NSW’s approach to heating and cooling thresholds to <a href="https://www.abcb.gov.au/Resources/Publications/Education-Training/NatHERS-heating-and-cooling-load-limits" target="_blank">other climate zones</a> in other states. The heating threshold puts a restraint on designing buildings that are optimised to mitigate extreme heat events.
This highlights the limitation of out-of-date climate files, and the current regulation that acts as a barrier to developing energy efficient designs for a future warmer climate.
Build to perform
A 2013 <a href="https://www.energy.gov.au/publications/evaluation-5-star-energy-efficiency-standard-residential-buildings" target="_blank">CSIRO study</a> found that houses with higher star ratings using more energy in summer.
One of the reasons is the trade-offs on the thermal performance of one building component against another in the Nationwide House Energy Rating Scheme (NatHERS) software. For example, a window without shading on the western façade is acceptable in a NatHERS simulation, whereas the same window would not be allowed if a <a href="https://www.abcb.gov.au/Resources/Tools-Calculators/Glazing-Calculator-NCC-2014-Volume-Two" target="_blank">glazing calculator</a> developed by the National Construction Code were used to demonstrate the thermal performance of a house.
Other issues are trade workmanship, such whether a building is airtight. Airtightness in residential buildings is ignored in the national construction code. However, considerable energy savings can be achieved if a house can be made airtight.
<a href="https://images.theconversation.com/files/283170/original/file-20190708-51262-8pfb7c.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/283170/original/file-20190708-51262-8pfb7c.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt=""></a>
 (Author provided)
Similarly, missing or displaced insulation in the ceiling, as shown above, can cause significant discomfort and additional heating and cooling costs. We all, from builders to homeowners, need to understand insulation must be carefully installed and cannot be moved later, or even well designed buildings will become inefficient.
Windows are the main option for ventilating most houses. However, if you live in a high-pollution or noisy area, or in a place with very little wind, open windows might not be desirable or practical. Consequently, households may not be getting enough fresh air to maintain a healthy indoor environment. A mechanical ventilation system, which uses little energy, is an ideal alternative.
The current weather files and heating thresholds used to develop minimum building standards are inadequate for our warming climate. Our report presents a framework for designing and building houses that consider climate change. We hope to see further research on other Australian population centres, so we can develop a comprehensive overview to help us build energy efficient and healthy houses for the future.<img src="https://counter.theconversation.com/content/120072/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;">

Australia's 2016 best small house listed at Broadbeach Waters

GUEST OBSERVER
Australia’s A$22 billion National Disability Insurance Scheme (NDIS) remains a key policy of the Coalition government. One of Prime Minister Malcolm Turnbull’s first major tasks was to sign agreements for statewide roll-outs of the NDIS in Victoria and New South Wales by 2019.
The agreements provide some insights into the interface of housing and the NDIS. They also document that the scheme will complement, but cannot replace, efforts of the housing sector, governments and families. A framework for funding NDIS participants and specialist disability housing providers is due to be released later this year.
NDIS still leaves a housing gap
The NDIS will provide “reasonable and necessary” equipment and supports for Australians with disability. However, the National Disability Insurance Agency has previously identified a significant housing gap for an anticipated <a href="https://chfa.com.au/sites/default/files/sites/default/files/docs/bonyhady_bruce_-_presentation_-_chfa_ndis_forum_-_27_march_2014.pdf">8</a>3,000 to 122,000 scheme participants.
The 2015 report from the Senate inquiry into affordable housing described this as an economic issue of national importance. Access to affordable housing, the report said, needs to be a “central and cross-cutting theme” within a whole-of-government approach.
One group that needs lifetime housing and support are people with severe traumatic brain injury (TBI) and spinal cord injury (SCI). Australia has an estimated 1000 new cases of severe TBI and 136 new cases of high-level SCI or quadriplegia every year. Lifetime costs per case are estimated at $4.8 million to $9.5 million.
The Transport Accident Commission (TAC), Victoria’s no-fault road accident insurance scheme, has also identified a significant housing gap for its clients. Many live with TBI or SCI resulting from road accidents.
Opening doors to more independent living
The TAC has been developing new models of housing and support through Residential Independence Pty Ltd (RIPL). The aim is to provide options for more independent living.
RIPL Project One was a collaboration between the TAC and the Summer Foundation, a non-profit organisation focused on the issue of young people in nursing homes. The project delivered six smart-technology-enabled one-bedroom apartments within a 59-apartment private and social housing development in inner-city Melbourne. An on-site support staff hub provides outreach to tenants of the six apartments.
Tenants of RIPL Project One moved from living with family or friends, or traditional disability group home models. This was an exciting step on a pathway back to community living.
Continuously refining supported housing
In the past, investment in new supported housing (such as the $60 million federal Supported Accommodation Innovation Fund) has not included evaluation of the effectiveness of housing design and location. Investment in “learning from hindsight” can inform new projects if evaluation is carefully developed and effectively delivered.
The TAC has invested in a large-scale post-occupancy evaluation of RIPL Project One, through the Institute for Safety, Compensation and Recovery Research. This evaluation has been coupled with detailed actuarial cost-benefit analysis to guide future investment. This research was awarded an international Certificate of Research Excellence from the Environmental Design Research Association.
The post-occupancy evaluation findings have been documented in an interactive PDF report. This details key evaluation criteria and includes virtual panoramic tours. Viewers can explore the housing and technology design, the support delivered within these environments, and tenants' access to and use of spaces.
The research findings highlight the potential for an NDIS interface with housing provision. This has impacts on the quality of home life and social and economic participation for Australians with disability.
Creating better homes for people with disability
Key considerations include:
<ul>
<li>SITE LOCATION AND PLANNING: well-located housing close to accessible shops, public transport and other services builds community participation and inclusion.</li>
<li>DWELLING LAYOUT AND PLANNING: control of light, temperature and noise improves running costs of a home; layout builds tenant privacy; tailoring of joinery installation increases independence and reduces support needs.</li>
<li>HOUSING TRANSITION: site visits and familiarisation, and building links in the local community, with follow-up monitoring and support for effective routines, foster participation and independence.</li>
<li>SMART HOME TECHNOLOGY: training and consistent use of integrated technologies by tenants and support staff avoid technology abandonment and build autonomy and environmental control.</li>
<li>MODEL OF SUPPORT: exemplary built and technology design must be coupled with targeted disability supports to build skills for independent living.</li>
</ul>
As housing and support models are developed, iterative post-occupancy evaluation will build an evidence base of tenant experiences, outcomes, costs and benefits, and opportunities. This will inform well-designed, well-located housing using smart technology into the future.
Turnbull’s leadership of NDIS roll-outs must now be coupled with a co-ordinated whole-of-government approach to best-practice housing for people with disability. Strengthening NDIS implementation with a national housing strategy will reap both social and economic benefits for Australia.
