South East Queensland developer&nbsp;<a href="https://www.apartments.com.au/developers/gardner-vaughan-group">Gardner Vaughan Group</a>’s entry into the Gold Coast apartment market has progressed from pipeline to market, with its Chevron Island project Bronze on Chevron now formally available to purchase ahead of a planned 2029 completion.

The 119-apartment development on Mawarra Street marks the Brisbane-headquartered builder-developer’s first residential play in the Gold Coast, following its expansion south from Brisbane and the Sunshine Coast.

<a href="https://www.apartments.com.au/new-apartments/bronze-on-chevron-8-mawarra-street-surfers-paradise-qld-4217">Bronze on Chevron</a> comprises a mix of two-, three- and four-bedroom residences, with pricing starting from just over $1.5 million. The project is being delivered under Gardner Vaughan’s fully integrated model, with the group acting as both developer and builder, a structure it has consistently applied across its South East Queensland portfolio.

[smartcode_project:default project_id=107520 project_image_fid=367182]

Architecture has been designed by <a href="https://www.apartments.com.au/architects/cottee-parker-architects">Cottee Parker</a>, with landscape architecture by <a href="https://www.apartments.com.au/landscape-architect/jeremy-ferrier-landscape-design">Jeremy Ferrier</a>. The building presents as a single-tower scheme, with a focus on maximising outlook across both the Surfers Paradise skyline and the Nerang River.

Apartments have been planned with open-plan living zones extending to generous balconies, a response to the site’s dual-aspect positioning between river and ocean. Interiors follow a restrained coastal palette, with two colour schemes offered, and an emphasis on natural light and cross-ventilation.

[smartcode_project:default project_id=107520 project_image_fid=367181]

Resident amenity is concentrated across more than 1,250 sqm and includes a resort-style pool, gym, yoga lawn and rooftop entertaining areas. A function space with catering facilities forms part of the upper-level offering, alongside north- and south-facing outdoor areas.

Ground level will incorporate two retail tenancies, intended to extend the existing village character of the surrounding streets.

&nbsp;

[smartcode_project:default project_id=107520 project_image_fid=367200]

The project sits within walking distance of Thomas Drive’s established dining strip, while maintaining proximity to <a href="https://www.apartments.com.au/developments/surfers-paradise-qld-4217">Surfers Paradise</a> beach and broader Gold Coast amenity. The location, positioned on Chevron Island between the river and coastline, has increasingly attracted mid- to high-density development in recent years as the precinct evolves beyond its low-rise origins.

Gardner Vaughan’s move into the Gold Coast was first signalled in 2025, with the group identifying the region as a natural extension of its operations. Chief Executive Officer Simon Betteridge described the expansion as both “strategic and natural”, citing demand for well-designed apartments in lifestyle-driven markets.

Construction is expected to complete in early 2029.

Ellipse sets Castle Hill apartment record with $5.75 million Lily Lane penthouse sale

Fresh off completing its Delano Crows Nest development, Lindsay Bennelong has lodged plans for its next project, this time turning its attention back to the beach.

The developer, started 20 years ago by Clarendon Homes founder Peter Campbell, is proposing a 37-apartment scheme at <a href="https://www.apartments.com.au/new-apartments/17-25-ashburner-street-manly-nsw-2095">17-25 Ashburner Street</a>, Manly, positioned between the southern end of <a href="https://www.apartments.com.au/developments/manly-nsw-2095">Manly</a> Beach and East Manly Cove.

Lindsay Bennelong called on local architecture firm Platform Architects to design the new building, given their success at Finn, Lindsay Bennelong's current luxury apartment project on North Steyne.&nbsp;

According to the Design Verification Statement by Bridie Gough of Platform Architects, the proposal “relates to the current context but also the desired future character of taller buildings suitable to the new planning controls.”

The site has been identified as a Low to Mid-Rise Housing (LMR) location, given its position within 400 metres of the Manly Town Centre E1 Business Zone. The LMR controls are intended to unlock additional housing supply in well-located areas close to public transport, allowing developers to seek increased height limits to support greater density.

“The proposal seeks to provide this increased level of housing whilst being respectful of some of the smaller scale buildings also nearby,” the statement reads.

Lindsay Bennelong Development Director Leigh Manser said the project has been carefully aligned with the intent of the LMR controls. The proposal will significantly increase housing yield on the site, replacing four houses and 10 apartments, comprising 25 bedrooms, with 37 new apartments delivering a total of 94 bedrooms, whilst remaining compliant with the LMR controls.

“Sydney is in a severe undersupply, and delivering more dwellings and more bedrooms than what currently exists is exactly what the LMR policy is designed to activate,” Manser said, noting that nine of the apartments will be allocated as affordable housing for frontline workers.

“We have already commenced discussions with our community housing provider to determine the rental levels that frontline workers can realistically afford in this location,” he said. “These will need to sit well below the standard affordable housing benchmark of 20 per cent below market rent, and that has been factored into our feasibility and pricing.”

The design of the building incorporates a wave-like indentation running through the façade, referencing the nearby coastline and anchoring the building within its local context.

The&nbsp;Design Verification Statement says careful consideration has been given to the articulation of the building, ensuring the bulk is broken down to a more human scale through a defined four-storey podium."

The scheme includes a mix of one-, two- and three-bedroom apartments, as well as a full-time building manager's office and wellness facilities including a sauna and a gym.

“The design ensures a high level of amenity, with apartments offering generous private open space, many with expansive views, and all with comfortable proportions."

<a href="https://www.apartments.com.au/developers/lindsay-bennelong-developments">Lindsay Bennelong</a>&nbsp;is currently developing Finn Manly, just four full-floor luxury apartments on North Steyne. They recently welcomed residents to its 81-unit Delano Crows Nest development, a&nbsp;carefully scaled infill project designed to bridge&nbsp;<a href="https://www.apartments.com.au/developments/crows-nest-nsw-2065">Crows Nest</a>’s lively village centre with its surrounding heritage streets.

Designed by&nbsp;<a href="https://www.apartments.com.au/architects/ajc-architects">AJC Architects</a>,&nbsp;<a href="https://www.apartments.com.au/new-apartments/delano-crows-nest-27-57-falcon-street-crows-nest-nsw-2065">Delano</a>&nbsp;is arranged across three low-rise buildings, incorporating a mix of one, two, and three-bedroom apartments alongside a limited number of townhomes addressing Hayberry Lane. The architectural approach drew on the area’s Art Deco lineage, reinterpreted through contemporary detailing and framed by landscaped communal gardens.

The developer also has a development site in Maroubra.

First look: Lindsay Bennelong's new Manly apartment development revealed

Fifty-nine residences across 37 levels. No more than two per floor. With 80 per cent now sold, what remains at <a href="https://www.apartments.com.au/new-apartments/madeline-by-mosaic-broadbeach-22-mary-avenue-broadbeach-qld-4218">Madeline by Mosaic</a> is a short list.

Madeline was always conceived at a scale that sits outside the normal register of Gold Coast apartment living. The residences are half- and full-floor configurations, with the largest spanning more than 400 sqm, dimensions that place them closer to the penthouse end of the market regardless of where they sit in the building.

That scale is the organising principle of everything else: how the floorplans are laid out, how the materials read, how the connection between inside and outside works.

[smartcode_project:default project_id=150135 project_image_fid=355941]

The interiors were developed in collaboration with <a href="https://www.apartments.com.au/architects/fraser-partners-0">Fraser &amp; Partners</a>, the architecture practice&nbsp;<a href="https://www.apartments.com.au/developers/mosaic-property-group">Mosaic</a> brought in as design partner for the first time on this project. The palette runs to natural stone, textured timbers, and soft metallics, materials chosen as much for their tactile quality as their appearance.

Light cleverly shifts across surfaces through the day, and the design is explicit about wanting that to be noticed. Full-height glazing runs across the primary living areas, and where the building faces east toward the ocean, those walls of glass are doing real work: framing a view corridor that the site's position directly opposite Broadbeach State School's playing fields keeps permanently open.

That outlook is the site's most consequential asset. In a suburb where new towers continue to rise, a protected view line is genuinely rare, and the Mary Avenue address secures it. Residents at Madeline will look out over open parkland rather than the rear of another building, a distinction that becomes more meaningful with each new development approved nearby.

[smartcode_project:default project_id=150135 project_image_fid=355939]

The private outdoor spaces are sized to match the residences themselves. Terraces on the upper levels frame uninterrupted ocean panoramas, and the planning ensures that living areas extend into those outdoor zones rather than treating them as separate attachments. The flow between the two is part of the design intent, not an afterthought.

Inside, the finish specification reflects the same approach. Rich stone benchtops, warm timber joinery, bespoke hardware, each element specified to hold up over time rather than read as a moment in a particular trend cycle.

[smartcode_project:default project_id=150135 project_image_fid=3409]

Beyond the residences, the amenity offering extends that register. A lap pool and sun deck anchor the outdoor space, alongside a magnesium pool, cold plunge, steam room, and sauna.

A commercial-grade gymnasium, residents' lounge, library, and boardroom round out a programme that functions more like a private members club than a standard building amenity floor.

Construction has commenced under Mosaic's in-house building arm, with completion scheduled for late 2028.

Madeline by Mosaic delivers penthouse-level living across every apartment

Developer Fortezza Group is the latest to take its new apartment development, <a href="https://www.apartments.com.au/new-apartments/the-belvedere-5-7-church-street-nelson-bay-nsw-2315">The Belvedere in Nelson Bay</a>, to the NSW Government.

Fortezza, predominantly a South East Queensland developer, is the latest to apply for State Significant Development&nbsp; status through the NSW Government's Housing Delivery Authority, a pathway becoming favoured by developers to speed up the approval process.

They are planning 57 two- and three-bedroom apartments across 5-7 Church Street and 42 Donald Street, near d'Albora Nelson Bay Marina. The diverse apartment mix has sizes from just over 80 sqm to the largest three-bedroom penthouses that reach nearly 200 sqm.

<img alt="Fortezza" data-entity-type="file" data-entity-uuid="090360e1-66d7-43ad-b686-aba81f173bf2" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-04-29%20at%2010.22.40%E2%80%AFAM.png?VersionId=DMqF96eBZolqSAAAcugX0l66ueWng66m" />

Fortezza calls the project a "piece of Istria in Nelson Bay,"&nbsp;referring to the largest peninsula in the Adriatic Sea, shared by Croatia (90%), Slovenia, and Italy, which is known for its Roman history, Venetian-style coastal towns and inland hilltop villages.

They say the The Belvedere is strategically positioned at the apex of Nelson Bay, offering unrivalled views of the ocean, the bay and captivating topography of the area.

"Our commitment to maintaining the integrity of every view and sight line has been relentless," Fortezza Group says.

"Through extensive modelling and analysis, we ensure that each apartment enjoys the natural beauty of Nelson Bay, regardless of future developments. Each design element is carefully curated to harmonise with our European heritage, drawing profound inspiration from the Roman architectural marvels in Istria. The arches, the cascades of greenery and the stonework that define our project pay homage to the structures that once exemplified Roman grandeur."

Residents will have access to a pool, communal green spaces, an office and a coffee shop.

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.

<figcaption>Liverpool Quarter's plaza and community space</figcaption></figure> 
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.
