National property developer Goldfields has secured permit approval and appointed Victorian residential builder Ironside to begin work on The Brightly, an 11-storey, wellness and lifestyle-focused mixed-use development in Richmond.

<a href="https://www.apartments.com.au/developers/goldfields-group">Goldfields</a> has partnered with Dexus Real Estate Partnership Fund 1 (DREP 1) as co-investor and delivery partner in the <a href="https://www.apartments.com.au/new-apartments/the-brightly-9-15-brighton-street-richmond-vic-3121">Brighton Street project</a>.

With architecture and interiors by design practice Cera Stribley, The Brightly will feature 100 apartments, a resident-only wellness space, elevated dining experiences including a private dining room and a rooftop garden lounge, and ground-floor retail designed to integrate with Richmond’s local character.

The wellness space will feature a hot magnesium pool, cold plunge, steam room, sauna, and a vitamin-infused drinking station for refreshment and rehydration.

The Brightly’s focus on wellness extends to the rooftop landscaped by award-winning landscape architect Jack Merlo. It will feature canopied retreats and panoramic views of the Melbourne CBD and Richmond Hill treetops. Residents can also host guests with a private bookable dining space on the rooftop garden lounge and an indoor option on the first level.

Cera Stribley’s architectural vision drew inspiration from the surrounding area, using the flowing form of the train lines to shape the façade and create a dialogue between the building and Richmond’s rich history. The design features a four-level podium lined with lush greenery, honouring the suburb’s character and streetscape through its scale and materials.

There will be a choice&nbsp;of one-, two- and three-bedroom apartments, along with 19 exclusive sub-penthouses and penthouses, for prospective purchasers.

Lachlan Thompson, Goldfields’ CEO, said The Brightly will define a new kind of urban luxury for Inner East living.

“By drawing on Richmond’s vibrant mix of culture and hospitality, we’ve combined a lifestyle centred on wellness,” Thompson said.

“Its proximity to Melbourne's sports and entertainment precinct, the CBD, parks, and public transport makes it a prime location for both young professionals and those seeking a lifestyle change. What we’ve created is something remarkable - it’s real, it's Richmond, and it’s refined."

Dexus Real Estate Partnership Fund 1 Fund Manager, Jason Howes, said the Brightly is a high-quality investment in a high demand area with limited residential stock expected to be added in the coming years.

“Partnering with Goldfields, we are delivering a project that will redefine lifestyle focused urban living, offering residents exceptional design and amenities in one of Melbourne's most vibrant suburbs,” he said.

Onsite demolition is underway, with construction set to commence in April 2026 and completion targeted for late 2027. The Brightly will launch to market in mid-2026.

Goldfields greenlit for The Brightly, Richmond apartment development

The Allan Labor Government has revealed the remaining 23&nbsp;Train and Tram Zone Activity Centres as part of their plan to try and encourage development around some of Melbourne's most connected suburbs.

The new zones includes&nbsp;four smaller ‘neighbourhood centres’ to plan for more modest growth.

<ul>
	<li>Five are connected to the new Metro Tunnel and are now experiencing more services: Caulfield, Springvale, Noble Park, Yarraman (neighbourhood centre), and Dandenong stations.</li>
	<li>Eight are along the Frankston Line, which has recently returned to the City Loop: Hawksburn, Toorak (Beatty Avenue), Armadale (High Street), Malvern (Glenferrie Road), Glen Huntly, Ormond, Bentleigh, and Mentone stations</li>
	<li>Four are along the Sandringham Line, which will see an increase in services later this year: South Yarra, Prahran, Windsor and Elsternwick stations</li>
	<li>Three are on the Belgrave/Lilydale Line and benefit from five-minute peak services on average between Ringwood and the city: Blackburn, Nunawading, and Mitcham stations</li>
	<li>Two neighbourhood centres on the Alamein Line: Ashburton Station, plus a combined centre for the two closest stations on the metropolitan network Riversdale &amp; Willison stations</li>
	<li>One neighbourhood centre, Toorak Village, is a built-up area along the Route 58 tram.</li>
</ul>

The <a href="https://spatial.planning.vic.gov.au/activitycentre/">draft maps</a> will now be subject to detailed community consultation.

A similar process occurred for the first 10 pilot Activity Centres, with clear changes made as a direct result of this community consultation.

The final train and tram zones will set clear expectations on where new homes can go, cutting out delays, uncertainty and red tape and getting homes off the ground. The remaining two in inner-Melbourne that cover the entire Local Government Areas of Melbourne and Yarra, will go through a separate process.

In the immediate ‘core’ the plans allow for more homes in taller apartment buildings.&nbsp;Some cores have heights of six storeys, while others have up to 20 storeys, only when it is in line with those councils’ planning work.

Eligible buildings across the core will be ‘deemed to comply’ with planning rules and be exempt from VCAT review. Applications in the core that exceed the specified height of the site are not eligible for this fast-tracked pathway.

In the walkable catchments that surround the core, the plans propose gentler height limits and more low-rise apartments and townhouses. Heritage and landscape overlays will stay in place.

Inner catchments, representing up to a five-minute walk from the station or centre, propose limits of four storeys, or six storeys on larger blocks of more than 1,000 sqm, while outer catchments, representing up to a 10-minute walk from the station or centre, propose limits of three storeys, or four storeys on larger blocks of more than 1,000 sqm.

By 2051, train and tram zones will help deliver more than 300,000 new homes, with final plans for all 50 new centres expected to be completed by mid this year.

“We want more Victorians to have the opportunity to live close to public transport, their loved ones, and the things that matter to them,"&nbsp;Minister for Planning Sonya Kilkenny said.

“Whether it’s making it easier to build homes close to public transport, townhouses in our inner suburbs, or family homes with a backyard, our planning reforms are all about giving more Victorians real housing choice.

“While we’re focused on giving more young Victorians the opportunity to have a home of their own, the Liberals are blocking them from being built. They oppose more homes near transport, jobs and services.”

Glen Waverley’s housing shortage is set to be closed by 50 per cent with the approval of 795 new apartments which will rise from a former carp park in the heart of the suburb.

The plans, lodged by <a href="https://www.apartments.com.au/developers/sunkin-property-group">Sunkin Property Group</a> and now approved by the Victorian State Government Development Facilitation Program, will transform the 6,114 sqm carpark at 281 Springvale Road, into an $800 million, mixed-use residential and commercial development in the metropolitan activity centre.&nbsp;

“281 Springvale Road has received planning approval for a mixed-use, high-density development that will provide much needed homes in Melbourne’s middle-ring suburbs, including affordable housing," Sunkin's GM of Property and Development Lloyd Collins says.

"We worked closely with key stakeholders, the Department of Transport and Planning, Suburban Rail Loop Authority and Monash City Council to achieve an integrated design with an activated retail ground level that will add to the success of Glen Waverley.

Glen Waverley’s population is projected to grow by 9 per cent by 2031, with an additional 1,600 dwellings required to &nbsp;service the area.

Around 1,000 sqm of the former carpark has been retained by Monash City Council for a new Civic Plaza, creating a central meeting point and public transport link for the local community. &nbsp;

Sunkin Property Group acquired the site from Monash City Council in 2024. The site will remain open as a public carpark until development commences.

$800 million, 800-unit development permit fast-tracked for Glen Waverley carpark

UAE developer <a href="https://www.apartments.com.au/developers/arada">Arada</a> is continuing to unveil its billions of dollars of residential development it is set to deliver in Australia.

Following on its plans for <a href="https://www.apartments.com.au/news/nsw/arada-pitches-castle-hill-apartment-plans-ahead-of-2026-launch">431 apartments in Castle Hill</a>&nbsp;and the 2025 bail-out of construction firm Roberts &amp; Co so it can build its own developments, Arada&nbsp;has sought the NSW Government's approval for three towers in the Campsie town centre.

The project, dubbed One Campsie, has been designed by Woods Bagot and will deliver 346 apartments to Beamish Street across three interconnected towers rising 24, 32, and 39 storeys.

According to the Woods Bagot Architectural Design Report, the design seeks to “redefine the urban experience of a rapidly transforming town centre,” delivering housing above an activated ground plane that integrates civic and commercial uses. The design adopts a three-part vertical composition, stepping and articulating the tower to reduce visual bulk and respond to its varied urban interfaces.

<img alt="First Look: Arada unveils 39-storey mixed-use tower for Campsie town centre in State Significant Development bid" data-entity-type="file" data-entity-uuid="f515807f-7277-4ea5-8b2b-a5718514f30a" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Campsie%20podium.png?VersionId=J3oSJpOvye8gpg1kjagODjdhOb0Cl28I" />

At street level, the scheme places significant emphasis on public domain upgrades. A new civic plaza is proposed opposite the Orion Theatre, alongside a landscaped pocket park and a through-site pedestrian link connecting Beamish Street to Campsie Street and Ninth Avenue. The Urban Design Justification Report states that the proposal “builds on Council’s Master Plan by applying a place-led urban design framework that responds to the site’s unique conditions and enhances pedestrian experience and public benefit.”

The documents note that the development aligns with the Master Plan’s intensification strategy for sites within walking distance of the Metro station, while seeking to retain solar access to key public spaces. As outlined in the Urban Design Report, the proposal delivers “intensification within walking distance of the Metro Station while retaining solar access to key parks."

Woods Bagot’s design narrative also draws on local history and Aboriginal cultural context. The Architectural Design Report references engagement with Wangal Country and the Cooks River landscape, seeking to embed a connection to Country through material selection, planting, and public art integration. The broader vision, as described in the report, is to create a building that functions as a “community catalyst, not only as a place to live, but as a vibrant destination for work and play that brings people together, supports local culture, and contributes meaningfully to the civic identity of Campsie.”

Located at 124–142 Beamish Street and 16–18 Ninth Avenue, the site occupies a key stretch of Beamish Street, Campsie’s traditional high street, characterised by fine-grain retail, multicultural dining, and proximity to civic infrastructure including the Orion Theatre and Canterbury Civic Centre. The proposed civic plaza and pocket park aim to strengthen this interface, formalising connections between retail frontages, public transport, and community facilities.

If approved, One Campsie would mark one of the tallest and most ambitious additions to the suburb’s skyline, reflecting the broader shift toward higher-density living around transport nodes in Sydney’s middle-ring centres.

Syd​ney builder-developer Scion has lodged a State Significant Development Application (SSDA) for a 22-storey mixed-use tower at <a href="https://www.apartments.com.au/new-apartments/96-anzac-avenue-west-ryde-nsw-2114">96 Anzac Avenue, West Ryde</a>, marking a significant step in the transformation of the Victoria Road gateway precinct.

Designed by Turner, the proposal would replace an ageing two-storey commercial building with 145 apartments and 29 co-living rooms, above ground-floor retail and three basement levels of parking.

The 3,149 sqm site sits just 150 metres from West Ryde train station, at the edge of the suburb’s retail core and diagonally opposite Anzac Park. It occupies a prominent corner with frontages to both Anzac Avenue and Victoria Road, positioning it as a key transition point between established residential neighbourhoods and the commercial centre.

The scheme is being advanced under the Housing Delivery Authority pathway as a State Significant Development, alongside a concurrent rezoning to lift the site’s height and floor space ratio controls.

Turner says in the Architectural Design Report that the proposal "responds to a unique opportunity to support the revitalisation of West Ryde through the delivery of a landmark development that combines high-quality residential offerings with enhanced public realm and active ground plane uses.”

Scion will be pushing height almost five times higher than what had been pitched for the site before.

Turner says the increased scale aligns with Council’s strategic direction for the precinct, including the West Ryde Town Centre Revitalisation Strategy (2019), the Draft Masterplan (2021), and the West Ryde–Meadowbank Renewal Strategy (2023).

“The increased height and density proposed aligns with Council’s evolving strategic direction for the precinct, as outlined in the Draft Revitalisation Strategy (2019), the 2021 Draft Masterplan, and the broader West Ryde–Meadowbank Renewal Strategy (2023), which collectively call for higher density, transit-oriented development and design excellence."

Turner describes the vision as establishing “a contemporary, mixed-use development that contributes positively to the West Ryde town centre.”

<img alt="West Ryde" data-entity-type="file" data-entity-uuid="c5c22c11-92b8-4ca6-b77b-b5848ae0176d" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-02-12%20at%202.41.34%E2%80%AFPM.png?VersionId=aom0z8azYDw7Hl6.A6vDbCom5ozZICn5" />

The architectural response has been shaped by the site’s gateway role along Victoria Road and its proximity to Anzac Park and surrounding heritage elements, including the Sydney Water pumping station opposite the site.

The design process also incorporated consultation around Connecting with Country principles. The design report outlines engagement with Cultural Heritage Consultants Artefact and Aunty Julie, a Burruberongal woman of the Darug Nation, informing planting selection, materiality and potential public art opportunities.

Turner says the scheme aims to optimise the site’s capacity while balancing yield and amenity.

“The proposed scheme seeks to optimise the site’s potential by balancing yield, amenity, and urban integration. It will deliver a high-quality, mixed-use precinct that supports West Ryde’s ongoing transformation into a connected, accessible, and liveable centre."

Scion recently completed the build of its own development, The Sterling in Lane Cove. They are currently building Chatham in West Ryde, just 500m from the new proposal. Those 62 apartments will complete later this year.

Located in the of Sydney, Liverpool has just cemented itself as Sydney’s third CBD with the approval of the city’s tallest commercial office tower designed by <a href="/architects/fk-australia">Fender Katsalidis</a>. 
Developed by Macky Corp, the tower stands as a new gateway to Liverpool with 23 levels of grade A office space, 1,500sqm of co-working space and 640sqm of ground retail space. 
Additionally, the refurbishment of the New Commercial Hotel alongside with a two level development known as ‘The Stables’ which reflects the current heritage landscape and will be the podium to the curved glass tower above. The design draws upon the aesthetic of Liverpool’s brick buildings, green corridors and riverbank. The elegantly curved design of the tower is shaped to allow sunlight to enter the heritage precinct below. 
The alley with boutique retail, eateries, cafes and bars stretching from Bigge Street to Scott Street will provide <a href="/new-apartments/liverpool-nsw-2170">Liverpool</a> residents with a destination that the area truly deserves and has been long awaited.

<figcaption>Render of the Liverpool Quarter precinct with incorporated civic space and heritage buildings.</figcaption></figure> “Liverpool Quarter is a landmark project that will transform the area and enhance its surrounds,” says <a href="/architects/fk-australia">Fender Katsalidis</a> director Mark Curzon. “The building will act as a regional marker welcoming ones arrival into the city whilst creating an exciting new civic precinct celebrating its heritage.”

The Liverpool Quarter development is a response to the growing commercial interest in the area with the approval of nearby Western Sydney Airport and intimate connectivity to the Sydney CBD via public transport services. The development is welcomed by the Liverpool City Council as a perfect example for the type of developmental growth the new CBD needs.

“What drew us to Liverpool was the unprecedented infrastructure investment. We were attracted to this site given it was opposite the train station but also because of the three-storey heritage pub that was once the gateway to the city from the river and the east. Liverpool Quarter will stand proud as the gateway to the city and the refurbished pub alongside The Stables will create a destinational food and beverage precinct” says <a href="/news/mackycorp-lines-up-a-major-liverpool-office-development">Macky Corp</a> director Michael Hercus.

Katsalidis design gives plenty of “breathing space” between the existing New Commercial Hotel and the new tower, providing the area with a high level of community engaged, civic space.

“The people of Liverpool and the south-west deserve better. They are tired of travelling great distances to work and to experience quality food, beer and wine in a clean and safe environment. Liverpool Quarter will be a place for the people of Liverpool and the south-west to be proud of and call their own” says Hercus.

<a href="/new-apartments?bedrooms%5Bvalue%5D=0&amp;bedrooms%5Bvalue2%5D=5&amp;bedroom-prices%5Bvalue%5D=0&amp;bedroom-prices%5Bvalue2%5D=8&amp;field_local_government_area_name=Sydney%20%28City%29">Sydney CBD</a> and <a href="/new-apartments/parramatta-nsw">Parramatta</a> have been leading the commercial office market with low vacancy levels at 0.8% in some areas for A grade office buildings. Located opposite Liverpool Station, the $210 million dollar development will be amongst local destinations such as Macquarie Street, Biggie Park, Georges River, Liverpool Hospital and Westfield Liverpool and changes the shape and evolution of Australia’s fourth oldest town.

Liverpool’s current population of 210,000 is expected to explode to over 331,000 by 2036, thus being dubbed Sydney’s third CBD to which residents will be able to find pride and engage in their community.

Cromwell Property Group has sold its stake in Northpoint Tower to Early Light International, who will acquire a full ownership interest in the building.
Cromwell sold its 50% stake in the North Sydney tower for $300 million.
It had acquired its stake in the building for $139.35 million in December 2013.
The Hong Kong-based Early Light purchased the other 50% stake from Redefine Properties in August 2018.
The 44-level, mixed-use tower was originally constructed in 1977 and underwent a $130 million redevelopment that started in January 2016 and was completed in March 2018.
The lower level of the precinct focuses on convenience retail, while the upper level is dedicated to dining and leisure, inclusive of a rooftop bar.
There is also an eight-storey, 187-room Vibe Hotel.
Cromwell’s Chief Investment Officer, Rob Percy, said its sale of its remaining interest in Northpoint will provide certainty of funding for over $1.0 billion of acquisition opportunities.
“We will continue to recycle capital which, in conjunction with the placement, will allow us to accelerate the execution of our ‘Invest to Manage’ strategy,” Percy said.
“Northpoint Tower is a great example of what we can achieve, identifying and realising value in what was very much an unloved asset.
“We are delighted to have had the opportunity to partner with Early Light and know the asset is in good hands for the future.”
The sale is subject to FIRB approval and is expected to settle in mid-September 2019.

GUEST OBSERVATION
<hr>
The world’s current tallest skyscraper is the Burj Khalifa in Dubai. It’s 828 metres tall, which is over two-and-a-half times as tall as any skyscraper in Australia.
However, there is a skyscraper being built in Jeddah, Saudi Arabia, that will be over 1,000 metres tall when it’s finished. This will be the first building to ever rise over a kilometre high. It will also have 167 floors on top of each other!
So, how tall could we build a skyscraper? It would be difficult, but we could probably build a tower over 2,000 metres tall, which would be like ten normal skyscrapers on top of each other!
This is probably not a very good idea though. Building such a mega-tall skyscraper would use a huge amount of concrete and steel. Using lots of these materials when we don’t need to can be bad for the environment. It’s usually much better for the environment if we build smaller skyscrapers, maybe up to 300 metres tall.
In fact, there are lots of challenges when you design and build a mega-tall skyscraper.
Stopping the wind
The biggest difficulty is the wind. It blows on a skyscraper and tries to push it over, so you need to design a structure that keeps the building stable. The wind can also make a tower sway from side to side, so that people at the very top can even feel seasick.
Architects and engineers have lots of technologies to help stop this. Some of the tallest skyscrapers in the world have a giant pendulum at the top, inside the building, called a “tuned mass damper”.
<a href="https://images.theconversation.com/files/273734/original/file-20190510-183083-1ecnawq.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/273734/original/file-20190510-183083-1ecnawq.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt=""></a>
Here’s the tuned mass damper inside a very tall building in Taiwan called the Taipei 101 building. <a href="https://www.flickr.com/photos/rinux/2885421716/in/photolist-786x47-RrdhD-7L5rCf-cdadfE-9iWdLQ-isybyW-iq7AUJ-YMxAgb-5XS9AE-iq7uzQ-isxwRR-iq7xxU-isxND1-isxDju-isymzp-iq7st5-isyenS-isy5sY-71aoRR-iq7cEM-TwioMU-5vz76u-fQnMnK-uN592-fQnLhg-71epUy-iq8ajk-71ec27-4t7LZu-isxG3W-BxzS3-isxkUv-iq7ooj-47K2XM-22ybMDL-25X2Bnr-24zTwBZ-9x5PmD-5oUef8-5oYwzS-RpBdW-yUyNB6-5oYv7S-5VgHEu-5oYs5o-5oYxmh-69mpPE-5oUbkV" target="_blank">Flickr/riNux</a>, <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">CC BY</a>
Imagine a ball of steel the size of a house hanging from ropes inside a skyscraper. When the wind blows, the pendulum swings back and forth, absorbing the energy of the wind, to stop the building swaying.
Other buildings have pools of water at the top. When the wind blows it makes the water slosh around. Giant paddles in the pool absorb the water’s movement, which stops the building from swaying.
Another way to stop the wind is to use a clever skyscraper shape. When the wind blows on a skyscraper it creates swirls of air called vortices – like whirlpools in the sky.

The Burj Khalifa building in Dubai is thin at the top and wide at the bottom, with giant steps down the side. <a href="https://www.flickr.com/photos/103252903@N02/11869658586/in/photolist-j5T6XY-bvr8eu-2bdB2Ch-ssZPHD-sbz7eZ-ed12bb-s9FWWX-ssYYoM-ssZG5H-rwdq5T-s9GeMa-rw1Ruf-sqJApS-sbzvPK-sbz26x-bvr7sA-ssRVyo-sbqZFy-sbsCT9-s9GaN8-st2iQc-sbyXCF-972TXn-9mFgfn-s9GDzk-9r5pz2-ssRyyh-ssZdct-sbs8ZN-s9GJ9R-drKBAV-rwcyVF-s9FATv-ssReuA-rwd8Wa-rwcKLP-sbsE6s-s9G5Gr-sqJsv5-sbywGP-st2aGt-sbqQSw-sqHUpw-ssR47w-dRA4ND-sbqw5m-FhbBWd-sbtfYW-sqJfXq-s9GLsi" target="_blank">Flickr/Adam</a>, <a href="http://creativecommons.org/licenses/by/4.0/">CC BY</a>
If these happen regularly, it can make the building sway back and forth. The Burj Khalifa building in Dubai is thin at the top and wide at the bottom, with giant steps down the side. The steps make the vortices happen at different heights to help stop the building from swaying in the wind.
Getting to the top
Another big challenge is how do you get to the top of a building that is one kilometre tall? Walking up the stairs isn’t an option as there would be more than 3,000 steps!
Taking the lift would be a good idea, but you’d need a very fast lift. Otherwise it would take ages to get up or down the building.
Some of theses lifts can travel at 70km/h, the speed of cars on a highway. At that speed you would go past five floors every second and soon be at the top.
You would also need lots of lifts in a kilometre-high skyscraper. The Jeddah Tower will have 59 of them! They will have super-strong carbon fibre ropes to carry the lift, as normal ropes just aren’t strong enough.
