Adding to Chatswood’s growing skyline, <a href="https://www.apartments.com.au/new-apartments/the-anderson-chatswood-54-56-anderson-street-chatswood-nsw-2067">The Anderson</a> is grounded in a simple principle: apartment living in a major centre does not have to come at the expense of space and outlook.

Set on Anderson Street in the heart of <a href="https://www.apartments.com.au/developments/chatswood-nsw-2067">Chatswood</a>, the new residential tower, a collaboration between developers <a href="https://www.apartments.com.au/developers/changfa-group">Changfa Group</a> and <a href="https://www.apartments.com.au/developers/huirong-group">Huirong Group</a> with architecture and interiors by <a href="https://www.apartments.com.au/architects/ajc-architects">AJC Architects</a>, will introduce 122 apartments that prioritise generous proportions, considered orientation, and a strong connection to the surrounding heritage precinct.

The design originated from a Design Excellence Competition, where AJC proposed a building that combines suburban-style apartment scale with the density expected in a transport-rich centre. The development will include more than 1,800 square metres of retail and commercial space at street level, landscaped communal roof terraces, and a ground-floor pocket park framed by canopy trees. Together these elements aim to create a building that integrates with Chatswood’s evolving streetscape while maintaining a strong residential focus.

[smartcode_project:default project_id=151353 project_image_fid=353250]

A key driver behind the architecture was the desire to deliver family-sized apartments rarely seen in the Chatswood market. The Anderson includes a mix of one to four-bedroom apartments, with around 35 per cent of the residences configured as three or four-bedroom homes. At the top of the building, two double-storey penthouses span approximately 200 square metres each, reinforcing the project’s emphasis on scale and long-term liveability for both downsizers and intergenerational households.

Orientation and outlook were central to the planning of the building. The apartments are positioned to maximise views to the north and east across Chatswood’s heritage precinct, with upper levels capturing glimpses of the Pacific Ocean. South-facing apartments gain distant views toward the Sydney CBD and Harbour Bridge, while the building’s configuration intentionally reduces western exposure at lower levels to minimise overlooking toward the nearby railway corridor.

The external design references the character of the surrounding conservation area without replicating it directly. A brick podium anchors the building to the street and introduces a series of architectural portals that draw inspiration from the nearby Chatswood Presbyterian Church. Above this base, the tower shifts to a lighter, more open expression defined by horizontal lines and carefully detailed balconies that balance privacy with outward views.

[smartcode_project:default project_id=151353 project_image_fid=353254]

Toward the top of the tower, AJC introduces a distinctive lantern-like element formed by sliding screens. These screens provide both solar shading and privacy while also creating a visual marker for the building within the Chatswood skyline. The feature reinforces the architectural intent of the project, a structure that is visually refined while still responding to the practical requirements of apartment living.

Inside the residences, interior architecture by Hayball focuses on clear spatial flow and practical everyday use. Open-plan living areas connect directly to large balconies, extending the internal living spaces outward and allowing natural light to move deeper into the apartments. Kitchens are designed as central working spaces with premium appliances and carefully selected materials, positioned to serve both daily living and entertaining.

[smartcode_project:default project_id=151353 project_image_fid=353256]

Bathrooms follow a similarly restrained design language, using refined fixtures and materials to create calm, functional spaces, while wardrobe areas adopt a gallery-style layout with integrated lighting and generous storage. These elements reflect a broader design approach that prioritises clarity, functionality, and durability over decorative gestures.

Positioned just a short walk from Chatswood Interchange, residents will have direct access to rail, metro, retail, and dining. The Metro extension allows travel from Chatswood to Martin Place in approximately 11 minutes, placing the CBD within easy reach for residents while maintaining the convenience of a walkable North Shore neighbourhood.

One-bedroom apartments at The Anderson start from $1,022,000.

How AJC designed The Anderson to bring oversized apartment living to Chatswood

<a href="https://www.apartments.com.au/developers/bridgewell-development">Bridgewell Capital</a> has lodged plans for a major mixed-use apartment development in the heart of Maroubra, seeking a significant uplift in height and density controls to deliver 120 apartments and a 120-place childcare centre near Maroubra Junction.

The State Significant Development application, filed through the NSW Government’s Housing Delivery Authority pathway, covers a 3,270 sqm amalgamated site at 251-257 Maroubra Road and 133-135 Garden Street. The proposal includes a concurrent rezoning that would increase the maximum building height from 12 metres to 35.6 metres and lift the floor space ratio to 4.02:1.

Designed by <a href="https://www.apartments.com.au/architects/bka-architecture">BKA Architecture</a>, the project would replace a mechanic’s workshop and several detached homes with a 10-storey residential building above four basement levels.

The scheme comprises 120 apartments, including 27 affordable housing units to be managed by a community housing provider for 15 years, alongside 203 basement car spaces and 92 bicycle spaces. A childcare centre occupying nearly 900 sqm of floor area would sit at ground level and be capable of accommodating 120 children and 22 staff.

<img alt="First look: Bridgewell plots 120 apartments and childcare centre in Maroubra town centre" data-entity-type="file" data-entity-uuid="038a0639-f9e4-4303-8fcc-d43e73fa480f" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Bridgewell%20pers.png?VersionId=eGBElxmNqJW.YF3JFYgHTnPgAstdyXR3" />

According to the Design Report, the project has been conceived as a “gateway proposal” that responds to Maroubra’s evolving urban character and its proximity to the town centre.

“Designed to complement the character of Maroubra’s town centre, this gateway proposal features a building scale that matches its surroundings,” the report stated.

“It integrates residential units above a ground-level childcare centre, fulfilling the strategic objectives of the Randwick City Council Masterplan.”

The apartment mix is weighted toward larger residences aimed at families and downsizers, reflecting changing demographics in the Randwick LGA and increasing demand for medium-density housing close to transport and amenity.

BKA Architecture said the proposal seeks to reinforce Maroubra Road as a civic spine while improving the pedestrian experience around the site through landscaping and upgraded public interfaces.

“The design capitalises on the following site opportunities: reinforcement of Maroubra Road as a civic spine, enhancement of pedestrian pathways and the public interface via new landscaping, and strong market demand for two and three-bedroom apartments to support families and down-sizers,” the Design Report noted.

<img alt="First look: Bridgewell plots 120 apartments and childcare centre in Maroubra town centre" data-entity-type="file" data-entity-uuid="ee509779-3c7e-4918-b03d-761c785459d0" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Bridgewell%20site.png?VersionId=eZC4Ruyn.C7O.Qwfr1SVeP5.ds1c5.66" />

The building has been designed with setbacks and articulation intended to transition between the commercial intensity of Maroubra Junction and the surrounding lower-scale residential neighbourhoods. Communal open space is proposed on level one, while upper-level apartments would secure views towards Port Botany, Maroubra Beach and Sydney’s eastern suburbs.

The development sits around 200 metres east of the Maroubra Junction intersection of Anzac Parade and Maroubra Road, within one of Randwick’s identified strategic centres. The site is close to Pacific Square Shopping Centre, major bus routes, schools, parks and future cycling infrastructure proposed under the Maroubra Junction Masterplan.

The Maroubra proposal aligns with broader NSW Government initiatives encouraging higher-density housing near established centres and transport corridors, particularly where affordable housing is incorporated.

Bridgewell is also working on a <a href="https://www.apartments.com.au/news/qld/goldfields-sets-the-stage-as-quartet-milton-launches">new 55-unit project in Killara</a>.

National diversified developer <a href="https://www.apartments.com.au/developers/goldfields-group">Goldfields</a> has launched its latest Brisbane apartment project, <a href="https://www.apartments.com.au/new-apartments/quartet-milton-33-manning-street-milton-qld-4064">Quartet Milton</a>, marking its entry into the sought-after inner-city suburb just two kilometres from the CBD.

The circa $100 million development will rise 18 storeys and deliver 131 apartments, offering a mix of one, two-, and three-bedroom residences.

Ideally located on Manning Street, Quartet residents will be within 300 metres of Milton Station, 500 metres from the Milton Ferry Wharf, and a short walk to Milton Markets, the iconic Park Road, as well as a range of breweries and cafés.

[smartcode_project:default project_id=108736 project_image_fid=367993]

Designed by architecture firm <a href="https://www.apartments.com.au/architects/rothelowman">Rothelowman</a> and brought to life by <a href="https://www.apartments.com.au/architects/cera-stribley-architects">Cera Stribley</a>, the building features a simple, gridded façade paired with generous glazing to enhance views, maximise aspect, and capture both sunrises and sunsets from within the apartments and their generously sized balconies.

Residents will have access to a 1,000 sqm rooftop, curated to balance wellness and entertaining, in response to increasing demand for wellness-focused shared spaces.

"We've approached Quartet Milton as a complete lifestyle offering, not just apartments, but a place where the design, amenities, and location all work together in a meaningful way," says Goldfields Managing Director Lachlan Thompson.

"Buyers are looking for that sense of confidence, knowing the vision has been carefully thought through not just by us as developers, but by all our consultants appointed to bring this together, and that it will be delivered to the standard they expect."

[smartcode_project:default project_id=108736 project_image_fid=368000]

Cera Stribley Co-Founder and Managing Principal Domenic Cerantonio said the rooftop is designed to feel like a place "you'd genuinely use every day."

"A 25-metre pool framed by city and mountain views, wellness areas, and private dining spaces for evenings with friends create a setting designed for year-round comfort and effortless Brisbane living."

[smartcode_project:default project_id=108736 project_image_fid=367999]

In addition to the 25-metre pool, the rooftop will include a sauna, cold plunge, fully equipped gym, and zen gardens, all complemented by panoramic views of the city and river.

While the building is expected to appeal predominantly to owner-occupiers, Goldfields anticipates interest from investors seeking strong rental returns, driven by the project's design, location, and the city's projected capital growth in the lead-up to the 2032 Brisbane Olympics.

[smartcode_project:default project_id=108736 project_image_fid=367991]

<a href="https://www.apartments.com.au/developments/milton-qld-4064">Milton</a>, widely regarded as one of Brisbane's most desirable inner-ring suburbs due to its lifestyle offering and proximity to the CBD, has experienced a shortage of new apartment supply in recent years.

Goldfields is already active in the Brisbane residential market through its Ripley Valley masterplanned community, Hayfield. The 109-hectare neighbourhood is already home to more than 300 families and features a large community park.

Plans for the precinct include a 4 km running track, future schools, and retail and commercial amenities, all within a 35-minute drive of the Brisbane CBD.

Goldfields also plans to deliver a new mixed-use tower at 88 Robertson Street in Fortitude Valley, within the James Street precinct. The project will include 16,000 sqm of boutique commercial space, a level of wellness facilities, and a rooftop restaurant and event space, akin to Goldfields House in South Yarra, its flagship mixed-use development on Chapel Street, which is crowned by the Beverly Rooftop bar, one of Melbourne’s best-known venues.

Goldfields sets the stage as Quartet Milton launches

<a href="https://www.apartments.com.au/developers/stockland">Stockland</a> and Homes NSW have taken the next major step in the transformation of Waterloo Estate, lodging a Concept State Significant Development Application and concurrent rezoning proposal for the renewal of Waterloo South.

The proposal, now on public exhibition, outlines plans for around 3,300 new homes across the 12.3-hectare precinct. A minimum 30 per cent of residential gross floor area will be delivered as social housing, approximately 20 per cent as affordable housing, and a maximum 50 per cent as market housing. The redevelopment would more than quadruple the number of homes currently on the site and more than double the existing supply of social and affordable housing.

The renewal of Waterloo South forms the first stage of the broader Waterloo Estate transformation and is set to unfold over the next 10 to 15 years. The estate currently contains 750 social housing dwellings and 120 private homes.

<img alt="First look: Stockland and Homes NSW unveil plans for 3,300-home Waterloo South renewal" data-entity-type="file" data-entity-uuid="ba2da34b-171b-4ff1-b0c7-4baf0bce97f2" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Waterloo%20public.png?VersionId=S5apPKOqjPHJhk_SzCvdVPxsEBYs300o" />

The proposal, prepared by <a href="https://www.apartments.com.au/architects/sjb-architects">SJB</a> and Beam Planning, spans 10 street blocks bounded by Cope, Raglan, George, Wellington, Gibson, Kellick, Pitt and McEvoy Streets, directly adjoining the Waterloo Metro Station precinct and within walking distance of Redfern and Green Square stations.

Under the masterplan, building heights would range from two to 33 storeys, delivering approximately 282,485 sqm of residential floor space alongside at least 10,000 sqm of non-residential uses and a minimum 5,000 sqm of community space. The planning framework has been specifically structured to support the mixed-tenure outcome, with the residential gross floor area capped at a maximum 50 per cent market housing allocation.&nbsp;

The Urban Design Report describes the vision as creating “a unique and vibrant mixed-tenure housing precinct that supports the needs of the community and delivers much needed housing in response to National and State Government priorities.”&nbsp;

<img alt="First look: Stockland and Homes NSW unveil plans for 3,300-home Waterloo South renewal" data-entity-type="file" data-entity-uuid="6e1a6d8b-0626-4fa7-94fc-aa91c0af86dc" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/waterloo%20per.png?VersionId=duyiJTFOeezTNdM22leI3SoHuqnW6ZaY" />

A major focus of the revised proposal has been increasing the social and affordable housing component. The Minns Government increased the affordable and public housing allocation from 35 per cent to 50 per cent after coming to office in 2023.

Minister for Housing and Homelessness Rose Jackson said the changes were critical to maintaining Waterloo’s social diversity.

“When we came to government, we immediately reviewed the plans for the Waterloo renewal and boosted the number of public and affordable homes from 35 to 50 per cent,” Jackson said.

“This was a crucial step to ensure Waterloo remains a welcoming place for people from all walks of life to call home now and into the future.”&nbsp;

Minister for Planning and Public Spaces Paul Scully said the project would reshape the precinct for generations.

“This concept DA brings thousands of new public, affordable and market homes on the doorstep of the Waterloo Metro station another step closer to reality,” Scully said.

“Importantly, alongside the new homes the plan also proposes new open space where residents and the broader community can gather, relax and play.”&nbsp;

Stockland Managing Director and CEO Tarun Gupta said the project had been shaped around long-term liveability and community infrastructure.

“As delivery partner, Stockland is proud to be working with the NSW Government on the renewal of Waterloo South – a significant project with community at its heart,” Gupta said.&nbsp;

The planning documents place strong emphasis on “Designing with Country,” recognising the site’s location on Gadigal land. The masterplan incorporates new east-west pedestrian links, activated streetscapes, rooftop communal spaces, retail frontages, and landscaped public areas intended to improve permeability and community connection throughout the estate.&nbsp;

The proposal also seeks to establish a more flexible planning framework for future detailed SSDAs, including updated provisions for educational uses, creative industries, rooftop communal areas, and active frontages. A minimum seven per cent of residential floor space will be delivered as affordable housing managed in perpetuity by community housing provider City West Housing.&nbsp;

The Social Impact Assessment prepared by Urbis describes the renewal as one of Australia’s most significant public housing transformations, identifying substantial long-term positive impacts associated with housing supply, accessibility, public domain improvements, and community infrastructure.&nbsp;

Stockland and Homes NSW have already commenced the first stage of resident relocations, with some tenants moved into newly completed homes at Waterloo Metro Quarter and the Boronia development nearby.

Travel Time

<html><body>
GUEST OBSERVATION
The average weekly commuting time in Australia has increased considerably since 2002. According to the latest Household, Income and Labour Dynamics in Australia (HILDA) <a href="https://melbourneinstitute.unimelb.edu.au/hilda" target="_blank">Survey released today</a>, workers averaged 3.7 hours’ commuting time per week in 2002, but this had increased to 4.5 hours by 2017.
In 2017, workers in mainland state capitals (Sydney, Melbourne, Brisbane, Adelaide, Perth) had consistently longer commute times than those living elsewhere. These city workers typically spent more than an hour travelling to and from work each day. The average was about 66 minutes. This is a 20% increase from the average of around 55 minutes in 2002.
As in past surveys, Sydney had the longest average daily commutes (71 minutes). In 2017, it was followed by Brisbane (67 minutes), Melbourne (65 minutes), Perth (59 minutes) and Adelaide (56 minutes). Reasons for the increasing commute time vary among different cities but may include increased road congestion, urban expansion and poor public transport services.
Average daily commuting times across Australia also increased from about 49 minutes in 2002 to almost one hour in 2017.
<img src="https://cdn.theconversation.com/static_files/files/666/Mean.gif?1564036035" width="100%">
Workers in the Northern Territory had the shortest commutes in 2017, averaging close to 35 minutes per day.
The HILDA analysis covers all workers aged 15 years and older. This includes those with commuting times of zero (that is, who work from home).
<img src="https://images.theconversation.com/files/285781/original/file-20190726-136744-124z3od.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="">
Daily commuting times are calculated by dividing the time spent travelling to and from work in a typical week by the usual number of days worked per week. Data source: HILDA
The survey, based on interviews with about 17,000 Australians yearly, also reveals that the share of people commuting two or more hours a day is increasing, from 12% in 2002 to 18% in 2017. Men are more likely than women to be long-distance commuters. And middle-aged workers (aged 25-54) are more likely to have long commutes than younger and older workers.
Interestingly, fathers of two children had the highest likelihood (27%) of having long commutes, while mothers with two children were the least likely (less than 13%). On the one hand, households with dependent children are more likely to live in suburban locations for the larger houses, potentially increasing commuting distance for workers in these households. On the other hand, female workers’ relatively lower wage rate and more household responsibilities, such as child rearing, may restrict them to choosing jobs closer to home.
Impacts on job satisfaction
According to the HILDA Survey, long-distance commuters (two hours or more a day) are less likely than short-distance commuters (less than one hour) to be satisfied with their working hours, work-life balance and even pay. Therefore, they have lower levels of overall job satisfaction. These long-distance commuters are more likely to quit or lose their jobs within the next year.
These results from the HILDA Survey align well with the findings of <a href="https://www.sciencedirect.com/science/article/abs/pii/S0966692318307269" target="_blank">our research</a>. Our findings suggest longer commutes not only impose physical and mental strains on workers but may also affect their work participation, engagement and productivity.
Negative impacts go beyond work
A growing number of studies have found long-duration commuting can <a href="https://www.sciencedirect.com/science/article/pii/S0965856410000960" target="_blank">reduce the time a person has for other activities</a>. These other activities, such as physical exercise, time with family, social activities and so on, are important for psychological well-being.
Lengthy commuting also potentially increases <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1467-9442.2008.00542.x" target="_blank">exposure to nuisances and hazards</a> such as traffic noise, crowds, congestion, pollution and uncomfortably hot or cold conditions. These can cause physical or emotional distress and have a direct influence on people’s physical and mental health.
What can policymakers do about this?
A better balance of jobs and housing within a smaller geographic area could help to shorten commuting distances and time. Planning policy such as polycentric cities – with multiple activity centres – have been proposed in Sydney and Melbourne, and could help achieve this.
Most Australians still rely on their cars for daily commuting. Aside from long travel distance, traffic congestion is another important factor in increasing commuting times. Encouraging alternative travel modes for commuting could potentially relieve congestion.
The HILDA Survey reveals that close to 28% of workers live and work in the same postcode. About 55% of workers live within 10 kilometres of their place of work. This suggests there is huge potential to promote active travel – cycling and walking – for daily commuting trips. Only for a minority (11%) are the postcodes of the home and place of work 30 or more kilometres apart.
High-frequency and reliable rapid public transport networks linking major residential and employment centres could encourage more medium and long-distance commuters to use public transport for daily commuting.
Finally, emerging transport technology, such as autonomous vehicles, is also promising to curb traffic congestion and reduce the “perceived” commuting time, if these vehicles are shared rather than owned by individuals.
Companies also have a role to play in helping to reduce commuting times and their impact on workers’ well-being. Flexible working times, which allow employees to avoid peak-hour travel, and a supportive company culture for working from home can help reduce weekly commuting time. In return, companies potentially benefit from improving employee job satisfaction and retention rates.

Australian city workers' average commute has blown out to 66 minutes a day: Runing Ye & Liang Ma

GUEST OBSERVER
Transport modelling for major road projects like Sydney’s WestConnex and Melbourne’s Western Distributor is at odds with what is known about motorists' behaviour.
A big part of the benefits claimed for new major roads in Australian cities is travel time savings. Evidence shows, however, that instead of saving travel time, these roads encourage us to travel further and often increase car dependency.
Travel time savings (calculated by transport models) have been used in transport project assessment since the 1960s and are often the main justification for projects. These models assume people try to minimise the “generalised cost” of travel (a combination of money cost and the dollar value of time). UK transport researcher David Metz notes that this assumption “is consistent with the idea that travellers take advantage of improved infrastructure to save time”.
Standard economic theory assumes people are motivated to obtain the maximum satisfaction (economists call it “utility”) from the consumption of the goods or services they can afford. This implies they are also motivated to keep the costs associated with that consumption to a minimum.
Where travel is concerned, motorists are assumed to minimise the generalised cost of that travel. Transport models use this approach to calculate travel time savings from new transport infrastructure.
A recent review of research, however, shows that people have a certain amount of time they are prepared to spend travelling each day. This means they don’t take advantage of added infrastructure to save time.
While new roads may reduce travel time for a period on some routes, in the longer run, these savings are spent on travelling further. This means the travel time savings put forward by proponents for these plans are not backed up by real world evidence.
As a result, these assumptions should not be relied upon for the assessment of road projects like WestConnex and the Western Distributor. For WestConnex, the value of calculated travel time savings is A$13 billion, or about half the claimed benefits for the project. Without these time savings, the costs of the project exceed the benefits.
Melbourne researchers John Odgers and Nicholas Low found that the forecast time savings for Melbourne’s CityLink project did not eventuate. They suggest that, rather than being based on evidence, transport policy is probably driven by political momentum to build more roads, because that’s what Australia has been doing for a long time.
Governments and their technical advisers also have strong incentives to find benefits to justify what politicians want to do.
Partly in recognition of the problems with transport modelling, some European cities have changed the way the problem is framed – from meeting forecast travel demand, to achieving a number of social and economic objectives through transport investment. Through sustainable urban mobility plans, different types of projects are favoured. These include: better integrated bus networks, more bus lanes, safer cycling and walking routes, improved park and ride facilities, and traffic calming measures that redesign streetscapes and reduce speed limits to improve mobility for all road users.
Rather than facilitating the movement of motor vehicles, this process emphasises creating safe, reliable and affordable access with less travel and a reduced environmental footprint. It also requires that engineers, urban planners, economists and other specialists sit down with the business and community sectors to build a consensus on what needs to be done. This is in contrast to current engineering-dominated methods.
In Australia, the Delivering Sustainable Urban Mobility report prepared for the federal government emphasises “putting people first” in urban transport. The report recommends a three-part approach: less travel, shifting away from trips by car, and improving vehicle fuel efficiency.
While this is somewhat encouraging, there is no recognition in the report that current methods of calculating the benefits of roads projects are unreliable because of the way time savings are calculated.
Despite a lack of evidence, the use of travel time savings calculated in transport models is deeply entrenched in government and professional practice. Until this flawed approach is replaced by something like sustainable urban mobility plans, government road spending will continue to encourage sprawl and car dependency, rather than save us time.
