Apartment buyers in New South Wales are set to gain a decade of insurance-backed protection against major building defects, after the NSW Parliament passed the Fair Trading and Building Legislation Amendment Bill 2026.&nbsp;

The Bill establishes decennial defect insurance, known in the market as Latent Defects Insurance (LDI), as an alternative to the existing two-year strata building bond. It cleared the Legislative Council with amendments on Tuesday evening (August 4, 2026), with the Legislative Assembly agreeing to those amendments shortly after.

Under the reform, eligible developers can satisfy their statutory bond obligation by taking out an approved decennial-style policy that gives owners 10 years of cover for major structural defects from completion, claimable directly, without first having to pursue developers or builders through costly legal action.&nbsp;

The change forms the final tranche of amendments arising from the 2021 statutory review of the Strata Schemes Management Act 2015 and related legislation.

Resilience Insurance, which originated the cover in Australia and has delivered it in NSW since 2022, welcomed the passage and credited the NSW Government for delivering it.

“This is protection apartment buyers have needed for a long time, and the credit for delivering it belongs to the NSW Government,”&nbsp;said Corey Nugent, CEO of Resilience Insurance.

“Minister Chanthivong and his team have shown real leadership in replacing an outdated two-year bond with cover that matches the lifespan of the buildings people are buying into. Reform like this is what good, evidence-based regulation looks like.”

Resilience has delivered LDI in NSW since 2022, protecting thousands of apartments, giving the State, and now the country, real-world evidence of how decade-long, no-fault protection works in practice.

The reform also places NSW within a wider national shift.

NSW is the third jurisdiction to put decennial cover into law. The ACT legislated for it in 2024, with the scheme taking effect in late 2025, and Victoria passed its own framework on 17 June. Between them, the three cover the majority of Australia's apartment market.

The reform commences once the legislation is proclaimed, which is expected in the coming weeks. From that point, developers of Class 2 residential apartment buildings can meet their statutory obligation with an approved decennial policy in place of the bond.

Buyers who purchased into projects that took out the cover early are among the first in the country to take keys to apartments carrying decade-long structural protection.

“With the legislation passed, the focus now turns to making it work for buyers,”&nbsp;Nugent said.

“There are already thousands of apartments in NSW covered by this insurance, bought by developers who moved early. The question every buyer should be asking in a display suite is a simple one: does this building come with 10-year defect cover, and who stands behind it?&nbsp;

“We look forward to working with the Government and the Building Commission in coming weeks as the framework moves to implementation, and to sharing what we have learned over the past four years so the protection reaches owners as smoothly and quickly as possible.”

Other states are working through their own reform programs. Western Australia has indicated that decennial cover is within consideration a later stage of its reform sequence, and Queensland has been examining the settings as it looks at the development pipeline ahead of the 2032 Olympics.

Resilience Insurance acknowledges the NSW Government’s continued focus on strengthening consumer protection while supporting housing delivery across the State.

NSW parliament passes 10-year defect insurance laws for new apartment buyers

Builder-developer <a href="https://www.apartments.com.au/developers/mcnab-developments">McNab</a> has wasted little time reshaping one of South Brisbane's most significant undeveloped apartment sites after acquiring the property earlier this year.&nbsp;

McNab has lodged plans to scrap an existing approval for two 30-storey towers and instead deliver a single 28-storey residential building, preserving part of the site for a future development opportunity.

The proposal, lodged over <a href="https://www.apartments.com.au/new-apartments/64-peel-street-south-brisbane-qld-4101">64 Peel Street and 9 Cordelia Street</a>, is for a residential-led mixed-use development comprising 124 apartments above a landscaped podium, alongside a boundary realignment that preserves part of the land for a future residential project.

<img alt="First look: McNab resets decade-old South Brisbane approval with 124-apartment tower" data-entity-type="file" data-entity-uuid="743bf564-3f8f-45fc-b8d3-bbf18f5b628f" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/mcnab%20Peel%20st%20podium.png?VersionId=EhCxGrVn_VFH3qTbKnI4WppGwaMnOn0t" />

Designed by <a href="https://www.apartments.com.au/architects/hayball">Hayball</a>, the development will deliver 119 two-bedroom and five three-bedroom apartments across 23 residential levels. A five-level podium will accommodate 135 car spaces, while the ground floor will include a 66 sqm commercial tenancy, an activated residential lobby with work-from-home spaces, and a publicly accessible landscaped plaza linking Cordelia and Peel streets.&nbsp;

Communal amenities will span Level 6 and the rooftop, including indoor and outdoor recreation spaces, a swimming pool, barbecue facilities, kitchen and dining areas, lawn space, sauna, steam room and yoga facilities.

The application also proposes a boundary realignment to create a standalone 1,290 sqm development lot while retaining an adjacent parcel for future redevelopment, allowing the balance of the site to contribute additional housing over time.

Hayball said the architecture has been shaped by the site's elevated corner position at the intersection of Peel and Cordelia streets and Brisbane's subtropical climate.

The design incorporates generous landscaped setbacks, a masonry podium wrapped with planting, large north-facing balconies, and a slender tower profile intended to maximise natural light, cross ventilation and long-range views. The rooftop has been conceived as a wellness-focused retreat overlooking Brisbane, with amenities positioned to capture views towards Mount Coot-tha and the CBD.

<img alt="First look: McNab resets decade-old South Brisbane approval with 124-apartment tower" data-entity-type="file" data-entity-uuid="c5f99e84-6ad8-4a87-82d1-869685b754d2" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/mcnab%20tower%20perspective.png?VersionId=Gw0IuJaSAlk.tvGBxInhZOcQAdIB..2b" />

The planning submission positions the proposal as a response to both changing market conditions and Brisbane's Kurilpa Sustainable Growth Precinct planning reforms.

McNab acquired the site after the previous approval was granted, with the existing scheme no longer reflecting current residential market demands, economic conditions, construction challenges, construction efficiencies or the quality of development outcome now being pursued, the planning report noted.

McNab continues to expand its residential development pipeline across Brisbane and the Gold Coast. The developer recently launched The Tannery in West End, securing more than 60 per cent of apartments before the project's public release. It is also delivering Elements Budds Beach in Surfers Paradise and Lucia Highgate Hill, an eight-apartment boutique development overlooking the Brisbane River.

A steeply sloping Bellevue Hill site is set to accommodate a new mid-rise apartment development, with plans lodged for 20 homes that respond to the site's dramatic topography.

The proposal for the consolidated land at <a href="https://www.apartments.com.au/new-apartments/138a-140-bellevue-road-bellevue-hill-nsw-2023">138A-140 Bellevue Road</a> has been designed by Sydney architecture practice Common Office, which has used the site’s substantial fall to distribute the building’s scale and unlock 20 apartments without presenting the full height to the street.&nbsp;

“The unique design strategy leverages the site’s substantial topographical fall to facilitate increased density, presenting a seven-storey profile to Bellevue Road while rising to 10 storeys at the rear,” Common Office said in its architectural design report.

The apartment mix spans one, two, three- and four-bedroom residences. Four two-bedroom apartments are designated as affordable housing, while the plans also include two adaptable dwellings. The mix is majority three-beds, with the typical three-bed apartment offering around 144 sqm internally, with balconies of around 15 sqm.

The affordable housing component represents 15 per cent of the residential floor area and allows the project to access additional height and floor space under the NSW Government’s in-fill affordable housing provisions. The site also falls within the inner area of the Low and Mid-Rise Housing Policy because it is within 400 metres walking distance of Double Bay Town Centre.

<img alt="First Look: Plans lodged for topography-led affordable housing project in Bellevue Hill" data-entity-type="file" data-entity-uuid="b1230d0f-3bfa-4a11-abaf-0928c66ef345" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Bellevue%20da.png?VersionId=dZeMK3P.OutGjN8ycjsxm8uNsj_QFWQv" />

Common Office has arranged the building around a masonry podium and a lighter upper volume, drawing on two recurring elements of Bellevue Hill’s established architecture: sandstone bases and the vertical proportions of local Inter-war Art Deco apartment buildings.

“The proposal is governed by a holistic design language that reconciles the solid horizontal masonry of the neighbourhood’s podiums with the elegant verticality of its Art Deco heritage,” the architect said.

“The building maintains a consistent rhythmic logic utilising deep recesses and a sophisticated material transition to break down the 10-storey scale into a series of articulated, human-scale volumes.”

<img alt="First Look: Plans lodged for topography-led affordable housing project in Bellevue Hill" data-entity-type="file" data-entity-uuid="0147f503-1af1-4d51-97fb-c2f1cba63a9d" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Bellevue%20bldg.png?VersionId=GoW7q3NlK67OpnePXhk7zvklrlKb72Qc" />

Large-format sandstone tiles will define the lower levels, establishing a robust base that negotiates the change in elevation from Bellevue Road. Above, red-tinted precast concrete frames, recessed balconies, anodised aluminium screens and expanded metal details will create a more vertically expressed façade. Integrated planter beds will introduce greenery across balcony edges and recessed sections of the building.

The elongated northern façade has been divided into three recessed vertical masses to reduce its perceived length. Triangular window elements and metal privacy screens reference the geometry of nearby Art Deco buildings while controlling overlooking toward surrounding homes. The southern elevation will incorporate further privacy screening, landscaped edges and deep balconies to maintain light and ventilation.

Private and communal landscaping is distributed throughout the development. A landscaped garden apartment is positioned within the lower portion of the site, while a communal terrace on Level 5 will include a central timber deck, barbecue facilities, resident planting plots and areas for outdoor dining and informal gatherings.

Common Office described the terrace as an elevated sanctuary designed to capture district views and sunlight. Its planting strategy incorporates endemic species associated with the Eastern Suburbs Banksia Scrub, extending the landscape vertically through the building and providing habitat for local flora and fauna.

A second communal outdoor area is proposed at roof level, with built-in seating, paved gathering areas and perimeter planting.

Bellevue Hill is enjoying renewed momentum in the new apartment market, with several boutique developments recently launched and currently under construction. Positive Investment Enterprise is delivering the 16-apartment Kew Palm House on Birriga Road, while Chanine Developments is also under construction at Florian, a 36-apartment project on Banksia Road.

South Brisbane's apartment pipeline continues to build momentum, with <a href="https://www.apartments.com.au/developers/trk-property-group">TRK Property Group</a> lodging plans for a 161-apartment tower on Montague Road as developers accelerate investment across the Kurilpa Sustainable Growth Precinct.

The proposal for 176–186 Montague Road would replace an existing office building with a 20-storey residential tower designed by <a href="https://www.apartments.com.au/architects/cox-architecture">COX Architecture</a>, adding to a growing pipeline of high-density projects reshaping one of Brisbane's fastest-evolving inner-city precincts.

The project has been conceived as a "living building", featuring a flowing tower form, extensive vertical landscaping, and generous communal spaces that respond to the evolving Kurilpa Sustainable Growth Precinct.

TRK Property Group Development Director Matt Kan said the project reflected the confidence developers have in South Brisbane's long-term future.

"South Brisbane is entering an incredibly exciting period, and we see Montague Road sitting right at the heart of that evolution," Kan said.

"With the former Visy site directly opposite us and significant investment planned throughout the broader Kurilpa precinct, there is a real sense of momentum around this part of the city and what it will become over the coming years.

"For TRK, this is an opportunity to be part of that next chapter and deliver a project that responds to where the precinct is heading, while contributing to the continued evolution of Brisbane's river edge."

<img alt="First look: TRK Property joins South Brisbane apartment surge with Montague Road tower plans" data-entity-type="file" data-entity-uuid="590fe1ad-f892-4446-a679-80e33a16d029" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/TRK%20tower%20facade.png?VersionId=uOJStrcKpyHFcPE1w6_9SMAFzVMCcZll" />

The scheme includes a mix of one, two, three and four-bedroom apartments, incorporating multi-purpose rooms in selected residences to provide additional flexibility for home offices or expanded living areas. The proposed mix comprises 15 one-bedroom, 13 one-bedroom plus MPR, 73 two-bedroom, 26 two-bedroom plus MPR, 30 three-bedroom, and four four-bedroom apartments.

Rather than adopting a conventional rectilinear tower, COX Architecture has developed a sculpted form inspired by the movement of the Brisbane River.

"The proposal has been designed by COX Architecture as a 'living building' that responds to the site's riverine setting, floodplain history and evolving urban context within the Kurilpa Sustainable Growth Precinct," the planning report states.

"The architectural form draws from the fluid nature of the Brisbane River, with a curved and undulating tower form that creates a varied architectural edge and avoids a conventional rectilinear tower expression."

The podium has also been designed as an architectural feature rather than a conventional parking structure, with cascading planting, screening and natural-toned materials softening its appearance. Resident parking is elevated above ground level to address the site's flood constraints, while habitable apartments sit above flood planning levels. Upper-level communal facilities are designed to accommodate shelter-in-place arrangements during major flood events.

Communal amenity is a major focus of the proposal. Around 1,815 sqm of shared resident space is proposed across the ground floor, level 19 and the rooftop, including co-working areas, indoor and outdoor recreation spaces, wellness facilities, dining and gathering areas, lawn spaces, a rooftop pool and spa, and extensive landscaping. At street level, a landscaped forecourt and approximately 345 sqm of publicly accessible open space along Montague Road are intended to improve the pedestrian experience while activating the building's frontage.

The development will provide 163 car spaces, including 152 resident bays and 11 visitor spaces, together with 144 bicycle spaces incorporating resident storage, visitor parking, bicycle maintenance facilities and e-mobility charging infrastructure.

The site sits within one of Brisbane's fastest-changing inner-city precincts, less than two kilometres from the CBD and within easy reach of South Bank, West End, the Queensland Cultural Centre and extensive public transport connections. The Kurilpa Sustainable Growth Precinct planning framework is encouraging higher-density residential development to help meet Brisbane's housing supply targets while supporting walkable, transit-oriented neighbourhoods.

Pikos Group has released the five-penthouse collection at its <a href="https://www.apartments.com.au/buildings/skye-residences-by-pikos-kangaroo-point-8-river-terrace-kangaroo-point-qld-4169">Skye by Pikos</a> development in Kangaroo Point, with early buyer interest indicating the flagship residences could eclipse every apartment sale previously recorded in Queensland.

The collection crowns the luxury riverfront development with five residences, including four completed penthouses and Skye One, a two-level sky home spanning more than 1,000 sqm that will be tailored to its eventual owner.

[smartcode_project:default project_id=90059 project_image_fid=374075]

Wanting to offer a fully customisable home, Pikos is offering Skye One as a blank canvas, allowing the buyer to work alongside the developer's design team to customise the home's layout, finishes and internal spaces.

The residence will feature a 247 sqm private rooftop terrace with its own swimming pool, sauna, steam room, outdoor kitchen and multiple entertaining areas overlooking the Brisbane River and CBD skyline.

The remaining four penthouses have been completed and are ready for immediate occupation, each offering four bedrooms, expansive open-plan living areas, soaring ceilings and private lift access.

[smartcode_project:default project_id=90059 project_image_fid=374059]

One of the defining features throughout the project is its use of Roman Classic Travertine, with more than 20,000 sqm of the natural stone imported from Italy after being personally selected by Pikos Group Founder and Executive Director Pedro Pikos, interior designer Julie Williamson and third-generation stone specialist Mario Caucci.

Pikos said the penthouse collection represented the culmination of the company's long-term vision for Skye.

"True legacy isn't measured by what we build today, but by what endures tomorrow," Pikos said.

"Our ambition is to create places that become more valuable with time, enrich the lives of generations, and stand as timeless landmarks long after we've stepped away."

[smartcode_project:default project_id=90059 project_image_fid=374060]

Williamson said the interiors were inspired by the natural character of Kangaroo Point and the Brisbane River rather than international design trends.

"Materiality tells the story of a place," Williamson said.

"We looked to the movement of the Brisbane River, the texture of the cliff face and the warmth of the surrounding landscape to create interiors that feel understated, enduring and unmistakably Brisbane."

Positioned above the Kangaroo Point cliffs, Skye places residents within walking distance of Howard Smith Wharves, South Bank and James Street while offering uninterrupted river and city views.

Demolish

<html><body>
GUEST OBSERVATION
Implosion is the most dramatic way of demolishing a building but it’s also the most wasteful and hazardous.
We are entering a new world where skyscrapers and other huge buildings are becoming redundant and need significant overhaul or replacement. The process is called unbuilding or, if you’re a bit highfalutin, deconstruction.
These so-called <a href="https://www.theage.com.au/national/victoria/spreadsheets-in-the-sky-are-putting-melbourne-s-liveability-at-risk-20191203-p53gek" target="_blank">spreadsheet towers</a> populate every major city. They signalled modernity and provided huge profits for those who built them. But these buildings are <a href="/news">profligate users of fuels</a> for light, power and services.
Most developed world cities started building skyscrapers after the second world war. These buildings were <a href="https://www.britannica.com/art/International-Style-architecture" target="_blank">International Style</a> architecture, unrecognisable is terms of a particular locale, universal in terms of their ubiquitous metal, concrete, glass – and fully air-conditioned. Now they are ageing, their use-by date is up and their balance sheet profitability no longer attracts.
The challenges of demolition and reuse
The question is: how do we safely dismantle these high-rise structures, which are generally located in busy cities?
Reminders of the dangers of explosive demolition are tragedies such as the <a href="https://www.canberratimes.com.au/story/6030620/katie-benders-family-commemorate-20-years-since-royal-canberra-hospital-implosion/" target="_blank">death of 12-year-old Katie Bender</a>. She was struck by flying debris when the Royal Canberra Hospital was razed in 1997 to make way for the new National Museum of Australia.
A recent demolition, and the <a href="https://www.archdaily.com/889563/soms-iconic-270-park-avenue-at-risk-of-becoming-the-largest-building-ever-to-be-demolished">tallest ever to be unbuilt</a>, is 270 Park Avenue, New York City (pictured). Its 52 floors were built in 1960 for the Union Carbide chemical company. The building was for 50 years the tallest ever designed by a female architect (Natalie de Bios of Skidmore, Owings and Merrill. Is that another low hit for gender equality?) Its replacement by architects Norman Foster will be <a href="/news">twice as high</a>.
The business of disassembling these skyscrapers is just now developing, but it will gain pace as more become obsolete.
Some still get imploded, but usually, in a busy city, demolition techniques must be unobtrusive, as quiet and clean as possible. The <a href="https://www.propertyobserver.com.au/https://us.macmillan.com/books/9780865476752">techniques used for cleaning up the World Trade Centre</a> testify to the wastefulness of a more destructive approach.
So how best to demolish a high-rise building?
Plenty of <a href="https://www.nytimes.com/2013/06/18/science/tricky-ways-to-pull-down-a-skyscraper">clever techniques to demolish</a> exist. Some start at the base and work up, others in reverse.
The 40-storey Akasaka Prince Hotel in Tokyo was slowly <a href="https://www.scmp.com/news/asia/article/1160452/eco-friendly-japanese-demolition-scheme-slashes-dust-and-noise">demolished in 2012-13</a> using a technique where a cap was built on top of the building. It was stripped floor by floor as the cap was lowered, so all the dust, mess and debris was contained and removed with no effect on the environment.
Buildings are wrapped in scaffold and protective fabric then literally dismantled in the reverse order to which they were built. In the process building waste can be recycled and reused rather than dumped.
Reverse building involves removing the glass, then the frames, taking off the wall cladding, then scraping away at the concrete and steel frames bit by bit. Concrete is removed to expose the steel reinforcing bars, which are then separately removed and recycled. In the process unwanted material can be uncovered, like asbestos, which needs particular care in handling.
Interiors are unbuilt the same way – remove floor coverings, cupboards, doors and lightweight walls, strip the electrical wiring and pipes, take out air conditioning and lifts, remove stairs and escalators.
These removalists act smartly, as materials and fabric are recycled and often reused for another building. It is a sustainable way of dealing with the issue. Things that might normally have been reduced to dust and mud by destruction are instead usefully salvaged and recovered for an extended life cycle.
As part of the benefits of this procedure, unbuilding provides <a href="https://www.huduser.gov/Publications/PDF/deconstruct.pdf">large numbers of construction jobs and associated employment</a> in transportation, waste management and recycling.
It also provides new construction sites. This means cities need not expand beyond existing boundaries and the infrastructure of services, roads and public transport need not be extended.
Building with an eye to unbuilding
What has interested those involved with this work is the capacity of building designers (let’s call them architects) to creatively improve their buildings in terms of life after use-by date. Techniques are being developed that assist in unbuilding and salvaging materials, even down to basic principles such as ease of access to pipes and wires, modular components and simplified connection practices.
The logic is that clarity of building structure and services makes retrieval simpler. Less complexity of materials and components means a building can be untangled more efficiently.
Fastening devices can be simplified and mechanical (rather than using glues and sealants), toxic materials avoided, materials selected with an afterlife in mind and structures designed for simplicity and accessibility. Also important is a clear set of as-built documents that map the original building so it can be disassembled.
Clear design thinking will have value for unbuilding and recycling in the future.
Making construction more sustainable
The construction industry is a main consumer of fuels, timber, steel and other metals, concrete and plastics. That demand drives the logging of forests, mining and extraction, leading to material production and transport that contributes to emissions and pollution.
The UK Green Building Council <a href="https://www.ukgbc.org/climate-change/">estimates</a> the construction industry generates about 22% of UK carbon emissions, uses 40% of drinking water, contributes 50% to climate change and over half our landfill waste, and accounts for 39% of global energy use. The US Environmental Protection Agency (EPA) also <a href="https://archive.epa.gov/greenbuilding/web/pdf/gbstats.pdf">reports</a> that the industry contributes to asthma and lung cancer by producing radon via contaminated applied finishes (paint).
Driving the need for much greater reuse of old building materials is an awareness of the fragility of our resources and the energy we use to consume them.<img src="https://counter.theconversation.com/content/129002/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important; text-shadow: none !important;">

Unbuilding cities as high-rises reach their use-by date: Norman Day

<html><body>
The developers charged over the illegal demolition of the Corkman, a 160-year-old Melbourne pub have been fined $1.325 million plus costs, after pleading guilty to breaching building and planning laws.
The Corkman Irish Pub in Carlton was illegally demolished in October 2016.
The magistrate Ross Maxted said only a big penalty would deter others.
Last year they were also fined nearly $600,000 by the EPA for illegally dumping asbestos debris from the demolition on a construction site surrounded by homes at Cairnlea, in Melbourne's north-west.
Developer Raman Shaqiri and his company 160 Leicester Pty Ltd pleaded guilty in May last year after knocked down the Corkman without building or planning approval. 
The company's other director, Stefce Kutlesovski, pleaded guilty to charges in January this year. 
Magistrate Ross Maxted fined the company $850,000, while Shaqiri and Kutlesovski were fined $220,000 and $255,000 respectively. 
Magistrate Maxted described the pair's behaviour as "reprehensible." 
The Corkman Irish Pub last sold for $4.76 million, $1.56 million above its 2014 auction reserve.
Located at 154-160 Leicester Street in the inner city fringe suburb of Carlton, the historic two storey pub, formerly the Carlton Inn, is located on a prime 456 square metre corner site.
The pub is directly across the road from the University of Melbourne law school. 
There were five bidders vying to buy the Corkman Irish Pub which is a traditional food and beverage venue with public bar, bistro dining, courtyard and first floor hostel accommodation.
The pub had been with the same owner since it last traded in 1987 for $900,000.
 
"The penalties will be imposed to deter such speculative and base mercantile thinking and behaviour."
 
After the demolition the developer duo committed "unequivocally" to rebuild the pub in a 2016 letter to planning minister Richard Wynne.
 
But the magistrate noted no building application had been lodged. 
 
"The company has not taken steps to honour that," Magistrate Maxted noted.
