A collection of just 25 large-format apartments and penthouses overlooking Goodwin Park is entering the Coolangatta market, with <a href="https://www.apartments.com.au/new-apartments/marea-residences-coolangatta-27-27a-dixon-street-coolangatta-qld-4225">Maréa Residences</a> combining a low-density, residential-only approach with uninterrupted park and Pacific Ocean outlooks.

Located at 27 Dixon Street, Maréa comprises three and four-bedroom residences alongside a limited number of dual-level penthouses, with the project positioned between Goodwin Park and <a href="https://www.apartments.com.au/developments/coolangatta-qld-4225">Coolangatta</a>’s coastal precinct.

Construction has commenced, with completion currently estimated for late 2027. Three-bedroom residences are priced from $1.8 million.

[smartcode_project:default project_id=150999 project_image_fid=374005]

The project has been designed around its northern outlook across the park, with the building’s architecture, landscaping and material palette intended to establish a connection with the neighbouring green space. The residences have been configured to maximise natural light and views across Goodwin Park towards the ocean.

Inside, the material palette incorporates timber, stone and brushed brass, complemented by curved detailing and ambient lighting. Kitchens and bathrooms carry the same natural material approach, while residences also include basement parking, storage and lift access.

Maréa’s penthouses are arranged over two levels and include private pools, adding another layer to the project’s focus on larger-format apartment living. Across the development, residences are configured with three or four bedrooms rather than the broader mix of smaller apartment types commonly found in larger projects.

[smartcode_project:default project_id=150999 project_image_fid=374010]

Resident amenity is concentrated at rooftop level, where landscaped entertaining terraces and pools take advantage of elevated views across Coolangatta and the Pacific Ocean.

The project has so far been particularly well received by local owner-occupiers and downsizers, according to Urban Activation Property Sales and Marketing Director Matt George, with the residential-only format, construction quality and northern park outlook among the features resonating with purchasers.

“The uninterrupted northern aspect overlooking Goodwin Park has been a key point of difference, with buyers attracted to the sense of serenity and open space the park provides, while still enjoying easy access to the ocean and being within walking distance of the lifestyle and amenities Coolangatta has to offer,” George said.

[smartcode_project:default project_id=150999 project_image_fid=374002]

“The combination of high-quality construction, a residential-only building, park outlook and proximity to the beach has resonated strongly with the local downsizer market.”

The Dixon Street address is within walking distance of Coolangatta Beach and the broader southern Gold Coast coastline, including the surf breaks at Snapper Rocks and Kirra. Coolangatta’s cafés, restaurants and retail are nearby, while Gold Coast Airport is also within close proximity.

Melbourne developer PDG has secured Victorian Government approval for its $1.5 billion Southbank development <a href="https://www.apartments.com.au/new-apartments/the-one-1-queens-bridge-street-southbank-vic-3006">The One</a>, clearing the way for the long-dormant riverfront site opposite Crown to finally be developed.

The Minister for Planning has approved the project at 1-29 Queens Bridge Street, with the Department of Transport and Planning issuing the planning permit following its assessment.

The approval will allow PDG to develop the prominent 5,059 sqm site with a major mixed-use tower comprising premium apartments, including branded residences, a luxury hotel and boutique office space.

PDG acquired the site in late 2024, with its position directly opposite Crown's main entrance and near Melbourne's Arts Precinct making it one of Southbank's most significant remaining development opportunities.

<img alt="PDG" data-entity-type="file" data-entity-uuid="3933013e-6332-4386-b9be-089df05caf17" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-08-27%20at%209.29.22%E2%80%AFAM.png?VersionId=sITIgBqDL0N3VNSMwWEmF5UA.uvcsRyu" />

Designed by COX in collaboration with ODO and PDG, the tower's architecture draws on the movement of the Yarra River, with six vertical pleats running the height of the sculpted facade.

The project will also see the heritage-listed Queens Bridge Hotel restored and incorporated into the development&nbsp;with new hospitality and public uses, including a rooftop venue.

A significant component of The One will be its residential amenity.

More than 5,000 sqm of resident facilities will be delivered across a single level, making it one of the largest consolidated residential amenity offerings proposed in an Australian apartment development.

The planning approval also incorporates a major upgrade of Queensbridge Square, which PDG will deliver in partnership with the City of Melbourne.

<img alt="PDG" data-entity-type="file" data-entity-uuid="73167fcd-1031-4b6f-a408-a064cfe45ed1" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-08-27%20at%209.29.17%E2%80%AFAM.png?VersionId=Pf1AEWxw6SNmBqR0zQW5lyEze.MtxgFp" />

The existing square will be revitalised as a new civic and pedestrian space along the Yarra River, strengthening the connection between the project, Southbank and the riverfront.

PDG Founder and Managing Director Vince Giuliano said the approval represented a major milestone for a site which has remained largely underutilised for more than 15 years.

“This is the most significant Planning Permit approval Melbourne has seen in recent years,” Giuliano said.

“For more than 15 years, this site has remained underutilised. This approval enables us to deliver a project that will contribute meaningfully to the revitalisation of Southbank, restore and reactivate an important heritage building, and create a new civic and hospitality destination for Melbourne.”

The latest approval follows an earlier planning permit issued by the City of Melbourne covering demolition works across part of the site at 9-29 Queens Bridge Street. Those demolition and early works are already underway.

PDG has also started generating early interest in the residential component from owner-occupiers ahead of a planned public launch in early 2027.

PDG secures approval for $1.5bn Southbank apartment development, The One

Local developer Harridan is seeking to turn its Woolloongabba apartment project into the first stage of a broader transformation of Burke Street, using a new 16-storey mixed-use building to establish a greener pedestrian connection toward the rapidly evolving Boggo Road transport and knowledge precinct.

The South East Queensland developer has filed plans for 154 apartments on the <a href="https://www.apartments.com.au/new-apartments/4-burke-street-woolloongabba-qld-4102">southern side of Burke Street</a>, where its proposal has been designed alongside a wider vision by LatStudios for the street.

That vision positions the southern side of Burke Street for buildings of 15 storeys and above, while envisaging lower-rise development of up to five storeys on the northern side to transition into Woolloongabba's existing character housing. It also proposes wider pedestrian verges, deep planting, new street trees and upgrades to the pedestrian approach to Boggo Road Station.

The Harridan development itself has been designed by Brisbane-based Arqus Design and will comprise 154 apartments across 16 storeys. The mix is weighted heavily toward two-bedroom apartments, with 121 proposed alongside 10 one-bedroom and 23 three-bedroom residences. There will typically be around 14 units per floor.

A lower-ground car park and three podium levels will accommodate 156 resident parking spaces, along with visitor and commercial parking. There will also be 154 resident bicycle spaces and 40 visitor bicycle parks.

&nbsp;

Harridan is a family-owned developer and part of the Holmwood Highgate Group, with more than three decades of development activity across South East Queensland. Its portfolio spans residential, commercial and industrial property, with current residential projects including Riverbank on Byron in Bulimba, Esperance Residences in Carina and The Precinct at Kinross Road in Thornlands.

Wooloongabba has been popular for apartment developers, particularly since the announcement of the 2032 Summer Olympics games in Brisbane.

While there have been a lot of development applications, it has failed to materialize into real supply.&nbsp;

Sarazin has been the major player in the area. They are under construction at Murcia Residences, on the fringe of East Brisbane and Woolloongabba. They have just launched <a href="https://www.apartments.com.au/new-apartments/the-stanley-residences-woolloongabba-8-trafalgar-street-woolloongabba-qld-4102">The Stanley Residences</a>, in Woolloongabba on Trafalagar Street. They also have Nuage coming soon on the nearby <a href="https://www.apartments.com.au/new-apartments/nuage-woolloongabba-14-wellington-road-woolloongabba-qld-4102">Wellington Road</a>.

<hr />
Lewis Land has opened the first completed sky home for inspection at Harbour Shores, giving buyers their first opportunity to step inside one of just three double-storey residences crowning The Waterline.

Each sky home comes with its own private marina berth, rooftop terrace and Broadwater views, combining the scale of a larger home with direct access to the boating lifestyle that underpins the wider <a href="https://www.apartments.com.au/new-apartments/harbour-shores-biggera-waters-564-oxley-drive-biggera-waters-qld-4216">Harbour Shores</a> masterplan.

[smartcode_project:default project_id=113271 project_image_fid=366708]

Lewis Land Head of Development Michael Long said the inclusion of a berth with every Sky Home had become increasingly valuable as marina access across the Gold Coast tightened.

“Marina berths are becoming increasingly difficult to secure across the Gold Coast, so including one with every Sky Home makes this a genuinely rare offering,” Long said.

“The private 70-berth marina will accommodate boats up to 12 metres in length and is positioned just 2.5 kilometres from the Broadwater, placing the open ocean only 15 minutes away.

“Being able to step out of your home onto your boat is a rare luxury, and it’s something residents here can look forward to when it opens later this year.”

[smartcode_project:default project_id=113271 project_image_fid=366709]

The display opening comes as construction completes on The Waterline, with the first residents expected to move in from mid-October.

The three Sky Homes range from 282 sqm to 367 sqm and each feature three bedrooms, three bathrooms, multiple living zones, expansive kitchens with butler's pantries and large balconies taking in the Broadwater outlook.

Each residence also has three secure basement car spaces and additional storage.

“This is the first opportunity the Gold Coast has had to step into Harbour Shores and see, touch and feel what we’re bringing to life here,” Long said.

“There are only three Sky Homes within The Waterline, ranging in size from 282sqm to 367sqm, with each residence featuring three large bedrooms, three bathrooms, multiple living zones, expansive custom-built kitchens with butler’s pantry, and large balconies capturing Broadwater views.”

<img alt="Harbour Shores" data-entity-type="file" data-entity-uuid="bab65e10-4fab-45e1-92d8-fc56e2ab98ff" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-08-25%20at%202.00.16%E2%80%AFPM.png?VersionId=XT8q76LsPkw3cYTsvN3JfFDaPLud90PN" />

Residents of The Waterline will have access to a private pool, along with Harbour Shores' wider collection of amenity including a lagoon pool, social clubhouse, tennis court, gym, yoga facilities and sauna.

Lewis Land partnered with Studio Collective to furnish the completed display, with the interiors designed to demonstrate how the residences could function as permanent homes rather than simply as show apartments.

Studio Collective Director Melissa Park said the surrounding waterways informed the interiors, but in a more restrained way than a traditional coastal scheme.

“We drew inspiration from the canals and coastal surrounds, but our approach was to interpret that subtly through layered materials and a grounded palette of earthy tones, rather than literal coastal references,” Park said.

“We introduced hero moments of green and teal to reference the surrounding waterways, while mirrored elements help reflect natural light.

“The result is a residence that feels elevated yet comfortable, somewhere buyers can genuinely imagine themselves living, entertaining and unwinding.”

Sky Homes are priced from $3.65 million.

Lewis Land is also offering private marina berths with The Residences, its limited collection of three and four-bedroom villas positioned directly along the Harbour Shores waterfront boardwalk.

Three-bedroom villas are priced from $2.99 million, while four-bedroom residences start from $3.19 million.

Harbour Shores is being marketed by Colliers International.

St Vincent de Paul Society Housing Australia has filed plans for a major mixed-use housing precinct on the southern edge of the North Sydney CBD, adding another significant proposal to a pocket around North Sydn​ey Station that is quickly becoming one of the LGA's busiest development zones.

The State Significant Development Application covers a 5,990 sqm site at <a href="https://www.apartments.com.au/new-apartments/1-19-mackenzie-street-lavender-bay-nsw-2060">1-19 MacKenzie Street and 211 Blues Point Road in Lavender Bay</a>, immediately south of Nor​th Sydney Station and between the commercial core and the lower-rise Lavender Bay Heritage Conservation Area.

Designed by Wardle, the proposal would deliver a new residential tower comprising 88 build-to-sell apartments and 19 affordable apartments, alongside a separate co-living building with 57 rooms and a building manager's studio.

It would also see the significant restoration and upgrade of St Francis Xavier Catholic Church, the adaptive reuse of the former school building, new parish facilities, retail, a new public square and around 1,000 sqm of publicly accessible open space.

<img alt="Vinnies North Sydney" data-entity-type="file" data-entity-uuid="d5dd7f87-a617-463e-b577-17541e01f0e9" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-08-26%20at%209.10.13%E2%80%AFAM.png?VersionId=4R8TsFN3P_LrrXO2HswTOIrx2blil8lh" />

The project is seeking a concurrent rezoning of the site to R4 High Density Residential and an increase in the maximum building height to allow a tower reaching RL120, or up to 20 storeys. The proposal was progressed through the NSW Government's Housing Delivery Authority pathway.

The build-to-sell component will be weighted toward larger apartments, with just six one-bedroom apartments compared with 31 two-beds, 43 three-beds and eight four-bedroom residences.

The 19 affordable apartments will comprise two studios, 15 one-bedroom apartments and two two-bedroom apartments, taking the total apartment component to 107 residences before the 58 co-living rooms are included.

<img alt="Vnnies" data-entity-type="file" data-entity-uuid="7d568ca5-cb90-4e18-96c6-d9795dba0c56" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-08-26%20at%209.10.05%E2%80%AFAM.png?VersionId=GY2R5M9VtQh0EKy1vajaea19PSLOPuRD" />

Wardle's design for the Vinnies site has sought to negotiate that emerging high-rise context while retaining the lower-scale character of MacKenzie Street and the adjoining heritage conservation area.

The main building adopts a three-storey podium and tower arrangement, with the podium aligned to the ridgeline and front setback of St Francis Xavier Church.&nbsp;Wardle has designed the podium with colonnades, seating, recessed entries and active ground-floor frontages, with sandstone-toned precast concrete and face brick referencing the materiality of the existing church.

The tower then steps back eight metres to the south and six metres to the north before rising in a sculpted form comprising four interlocking quadrants. Wardle has also introduced rounded forms and chamfered corners to reduce the tower's perceived bulk and improve view sharing with neighbouring development sites.

Resident facilities and outdoor areas are planned at the separation between the podium and tower at Level 3, oriented toward Sydney Harbour and the CBD skyline.

The tower itself will feature a glass reinforced concrete facade, with recessed balconies and deep reveals used both to provide shading and privacy and frame views toward the harbour and city. The lower levels take a different architectural approach, using brick and sandstone-toned finishes intended to establish a stronger relationship with St Francis Xavier Church. The Church itself will be conserved and upgraded for its continued use, while the former school building will be adaptively reused as part of the co-living component.

<img alt="Lavendar Bay" data-entity-type="file" data-entity-uuid="2d4418ad-90aa-4d49-af93-c80b140aea80" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-08-26%20at%209.09.47%E2%80%AFAM.png?VersionId=Kv4gzbsACaGvZSRuaqcfGC54jEJRXIDJ" />

&nbsp;

The proposal adds to an increasingly concentrated pipeline of residential development around Blue Street, MacKenzie Street and Lavender Bay.

Just west of the site, Central Element lodged plans earlier this year for one of the most significant residential developments proposed in Lavender Bay in recent years.

Central Element's SJB-designed scheme at 64-66 Lavender Street and 3-7 Middlemiss Street would deliver 163 apartments across two towers rising 23 and 32 storeys, replacing five existing apartment buildings containing 32 homes. The project also forms part of the Housing Delivery Authority pathway.

Immediately around North Sy​dney Station, another two significant proposals have emerged at 5 and 15 Blue Street.

Zurich Australian Insurance Properties is seeking to adaptively reuse its longstanding commercial building at 5 Blue Street, directly above North Sydney Station, rather than demolishing the structure.

Its SSDA proposes converting the building into a 14-storey mixed-use development with 62 apartments and 86 co-living rooms, together with ground-floor retail and a major refurbishment of Blue Street Plaza. The application is currently at the Response to Submissions stage.

During a heatwave in late 2018, Cairns temperatures topped 35°C nine days in a row and sensors at some points in the CBD recorded 45°C. <a href="https://theconversation.com/profiles/taha-chaiechi-106267"> </a>

Population and number of cities of the world, by size class, 1990, 2018 and 2030. 
The populations of these growing tropical cities already experience high temperatures made worse by high humidity. This means they are highly vulnerable to extreme heat events as a result of climate change.
For example, extremely hot weather overwhelmed Cairns last summer. By December 3 2018, the city had recorded temperatures above 35°C nine days in a row. Four consecutive days were above 40°C.

Cairns’ heatwave summer. Authors, using BOM temperature data
For our research, temperature and humidity sensors were strategically placed in the Cairns CBD to represent people’s experience of weather at street level. These recorded temperatures consistently higher than the Bureau of Meteorology (BoM) recordings, reaching 45°C at some points.

Local effects magnify heatwave impacts
Urban environments in general are hotter than non-urbanised surroundings that are covered by vegetation. The trapping of heat in cities, known as the <a href="https://www.nationalgeographic.org/encyclopedia/urban-heat-island/" target="_blank">urban heat island</a> effect, has impacts on human health, animal life, social events, tourism, water availability and business performance.
The urban heat island effect intensifies the impacts of increasing heatwaves on cities as a result of climate change.
<a href="https://images.theconversation.com/files/291226/original/file-20190906-175678-la15cl.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/291226/original/file-20190906-175678-la15cl.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt=""></a>
Projections of increased heatwave frequency for Cairns region using visualisation platform on Queensland Future Climate Dashboard.<a class="source" href="https://app.longpaddock.qld.gov.au/dashboard/#responseTab2"> </a>
But it is important to remember that other local factors also influence these impacts. These include the scale, shape, materials, composition and growth of the built environment in a particular location and its surrounding areas.
The differences between the BoM data recorded at Cairns airport and the inner-city recordings show the impacts of urban expansion patterns, built form and choice of materials in tropical cities.
The linear layout of Cairns has, on one hand, enabled the formation of attractive places for commercial activities. As these activity centres evolve into focal points of urban life, they in turn influence all sorts of socioeconomic parameters.
On the other hand, the form the built environment takes changes the patterns of wind, sun and shade. These changes alter the urban <a href="https://theconversation.com/city-temperatures-and-city-economics-a-hidden-relationship-between-sun-and-wind-and-profits-116064" target="_blank">microclimate</a> by trapping heat and slowing or channelling air movements.

The layout and structures of Cairns CBD alter local microclimates by trapping heat and altering air flows.
Shifting the focus to the tropics
To date, a large body of research has explored the undesired consequences of climate change and urban heat islands. However, the focus has been on capital and metropolitan cities with <a href="https://link.springer.com/article/10.1007/s00704-015-1703-8" target="_blank">humid continental climates</a>. Not many studies have looked at the economic and social impacts in the tropical context, where hot and humid conditions create extra heat stress.
Add the combined effects of climate change and urban heat islands and what are the socio-economic consequences of heatwaves in a tropical city like Cairns? We see that climate change adds another dimension to the relationship between cities, economic growth and development.
This presents a huge opportunity to start thinking about building cities that are not superficially greenwashed, but which instead tackle pressing issues such as climate variability and create sustainable business and social destinations.
In cold climates, heatwaves and urban heat islands are not necessarily undesired, but their negative impacts are more obvious and harmful in warmer climates. And these harmful impacts of heatwaves on our economy, environment and society are on the rise.
We have scientific evidence of the increasing length, frequency and intensity of heatwaves. The number of record hot days in Australia has <a href="https://www.climatecouncil.org.au/uploads/9901f6614a2cac7b2b888f55b4dff9cc.pdf" target="_blank">doubled in the past five decades</a>.

What are the costs of heatwaves?
Increased exposure to heatwaves amplifies the adverse economic impacts on industries that are reliant on the health of their outdoor workers. This is in addition to the extreme heat-related fatalities and health-care costs of heatwave-related medical emergencies. As a <a href="https://www.nccarf.edu.au/localgov/resources/protecting-human-health-and-safety-during-severe-and-extreme-heat-events-national" target="_blank">PwC report to the Commonwealth</a> on extreme heat events stated:
Heatwaves kill more Australians than any other natural disaster. They have received far less public attention than cyclones, floods or bushfires — they are private, silent deaths, which only hit the media when morgues reach capacity or infrastructure fails.
Heat also has direct impacts on economic production. A <a href="https://www.researchgate.net/publication/45660010_Temperatures_and_cyclones_strongly_associated_with_economic_production_in_the_Caribbean_and_Central_America" target="_blank">2010 study</a> found a 1°C increase resulted in a 2.4% reduction in non-agricultural production and a 0.1% reduction in agricultural production in 28 Caribbean-basin countries. Another <a href="https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2099798" target="_blank">study in 2012</a> found an 8% weekly loss of production when the temperature exceeded 32°C for six days in a row.
The 2017 <a href="http://www.agriculture.gov.au/abares/research-topics/climate/farm-performance-climate" target="_blank">Farm performance and climate</a> report by the <a href="http://www.agriculture.gov.au/abares" target="_blank">Australian Bureau of Agricultural and Resource Economics and Sciences (ABARES)</a> states:
"The recent changes in climate have had a significant negative effect on the productivity of Australian cropping farms, particularly in southwestern Australia and southeastern Australia."

It’s not just farming that is vulnerable. A <a href="/news">Victorian government report</a> report this year estimated an extreme heatwave event costs the state’s construction sector A$103 million. The impact of heatwaves on the city of Melbourne’s economy is estimated at A$52.9 million a year on average.

According to this report, economic costs increase exponentially as the severity of heatwaves increases. This has obvious implications for cities in tropical regions.
As the next step in <a href="https://www.researchgate.net/project/Evidence-based-Economic-Assessment-of-Urban-Comfort" target="_blank">our research</a>, we are examining the relationship between local urban features, urban heat islands, the resulting city temperatures and their direct and indirect (spillover) effects on local and regional economic activities.
