Design can achieve great things when environmentally enthusiastic homeowners have terrifically deep pockets. The rich and famous have long been ground-breakers in sustainable residential design, laying the foundations of a stealth-wealth aesthetic by funding innovative architects and new technologies.
Sustainability is now sexy with Hollywood heavyweights leading the charge.
Johnny Depp’s Bahamian island, Little Hall’s Pond Cay, cost him US$3.6 million in 2004 but the Pirates of the Caribbean star is rumoured to have spent millions more on enlisting the talents of home-brew hydrogen energy expert Mike Strizki to make the isle self-sufficient. Entourage actor Adrian Grenier, who hosts sustainability makeover TV show Alter Eco, has walked the talk with a house in Brooklyn, New York featuring walls insulated with recycled denim and rooftop gardens installed in an effort to eliminate the need for air conditioning.
Veteran actor Ed Begley Jr. famously built a luxury Californian home that achieved a LEED Platinum certification, the world’s most prestigious rating system for green buildings. He did it by recycling 96 percent of materials from the pre-existing house and adding a 9kw photovoltaic system and Tesla Power-wall.
Closer to home, in the early 2000s Cate Blanchett upcycled her former Sydney home with $1.5 million in renovations including a 20,000L water tank, high-tech solar panelling, low energy lighting and grey water recycling. Before eventually selling the Hunters Hill home and moving to London with husband Andrew Upton and their children, the pair were also instrumental in turning The Wharf Theatre green by installing approximately 2000 solar panels to provide 70 percent of the venue’s electricity and a system for rainwater harvesting.
Sean Triner, who works in environmental fundraising and is on the board of WWF Australia, wanted to challenge the idea that luxury and sustainability were mutually exclusive when he and his partner Christiana Stergiou built their Queensland home, Kingfisher House, in 2022.
Designed by PTMA Architecture and built by Kai Konstruct, the Currumbin Waters residence sits on a 5640sq m block, earned an energy-efficiency rating of 9.1 stars, featured twice in the national Sustainable House Day event and was the most-visited home in the Gold Coast Open House Architectural Festival in 2022 and 2023.
“We wanted a sustainable house, but also wanted to be able to have a pool heater, charge our electric car, or turn the aircon on whenever we felt like it — basically we wanted to have it all,” he says. “Our idea was to show that you can reduce your carbon footprint dramatically and still get all those luxuries you might want.
“Usually when you’re designing a home, you want form, function and price. Does it do the job? Does it look nice? And can we afford it? We just added a fourth pillar — form, function, price and sustainability.”
The six-bedroom, barn-style smart home has a central courtyard with an automated roof, a wine cabinet opening to a secret games room in the attic, a solar-heated swimming pool, a self-contained pool house, a cyclone-rated zinc roof, a 20kw PV solar power system and 12kw battery store, two 27,000L water tanks and an underground garage with 7kw WallBox electric car charger.
“Another really simple but important thing is to consider fauna by planting local species. Everything we’ve done in terms of landscaping includes varieties from the region and edible plants that don’t harm the wildlife,” Triner adds. “As soon as we’d done the planting we started to see tracks of everything from echidnas to wallabies and have even seen koalas in our trees.”
Architect Chris Major, co-founder of Welsh+Major, says sustainability is a priority among many clients of high spec builds today.
“There’s a whole range of things clients are looking for. The obvious add ons are around water tanks and solar panels but batteries are fast becoming sought after, especially for those with bigger budgets. Reliability of power supply is a genuine concern,” she says.
“Many clients also want to make sure there are great sustainable choices made in materials and sometimes that comes with an extra price tag. When you’ve got deeper pockets, that’s something you can definitely do; support local designers over using potentially cheaper imported products.”
European brands are being consciously replaced with domestic alternatives.
“Our local designers are equally talented,” Major says. “We also have such beautiful materials in Australia and if we can source them sustainably here, that’s what we’re interested in.”
For a long time, bigger meant better in the built environment, but that obsession with larger-than-life luxury is falling out of fashion.
“Now it’s more about the quality of spaces rather than the biggest house possible,” she says. “The move is towards luxury in a more restrained way.”
While intelligent architecture has always liked to push the envelope with the latest mod cons, the current environmental climate and recent natural disasters have had homeowners rethinking the their designer add ons.
“People are more conscious of the amount of energy that goes into building and running a home. It’s that idea of quality over quantity,” she says. “Passive solar design is really in focus now. It’s not that it was ever unfashionable, but some of these principles were forgotten in the midst of new technology.
“You can have solar panels, rainwater tanks, heat pumps and geothermal tech — which are all great — but they’re no substitute for just really good decisions around orientation, capturing cooling breezes and natural light.”
Savvy sustainable design can make a home a pleasure to live in, but really smart environmental decisions make for strong ROI, says David Medina of Sotheby’s International NSW, who regularly sells in the wealthy regional playgrounds of Byron Bay and the Southern Highlands.
“Sustainability is really important for buyers today,” he says. “Going back 15 years, one of the first questions I’d get asked was ‘Does it have access to power?’ That’s now moved from number one or two on the list to about number 10.” These days, he says, prestige purchasers are today more concerned about producing their own electricity.
“In terms of resale, it’s a huge bonus to not be reliant on town power. Although they’re probably not as troubled by running costs as the average Australian, the luxury of living totally off-grid gives people a lot of strength. If there’s a storm or blackout and you’ve got a generator that kicks in to back up the battery then it gives them peace of mind.”
He says buyers also want enhanced water storage solutions, double or triple-glazed windows as well as savvy orientation to capture the best views, natural light and airflow. Some are even opting for small wind turbines.
“When homeowners are building they’re thinking further ahead than ever,” says Medina. “Now the quality of products, the build quality, the architecture, is just developing at a rate of knots. I’m really excited to see what the next thing is going to be.”

As interest rates, inflation and market sentiment fluctuate, investors are being urged to focus on data, not panic.
Australia’s housing affordability crisis is being fuelled by chronic undersupply, planning delays and rising development costs, as politicians continue to focus on the wrong solutions.

Australia’s housing crisis will not be solved by first-home buyer incentives or tax changes alone, with leading property figures warning governments must tackle supply constraints if affordability is to improve.
Speaking at the Kanebridge Quarterly Property Leadership Summit in Sydney last week, expert project marketing specialist Sam Elbanna, property investor and fund manager Paul Miron and property consultant Karla McNeice said that a lack of housing supply remained the central issue facing the market.
Elbanna, Director of CPM Realty with more than 30 years’ experience in project sales, argued that successive governments had focused too heavily on stimulating demand rather than addressing the barriers preventing new housing from being delivered.
“The misconception is that politicians think the way to solve the housing crisis is to drive demand,” he said.
“The reality is that’s not the way. This is a supply-side problem, and it needs to be solved on the supply side.”
Drawing on his experience in project sales, Elbanna said policies designed to help first-home buyers often had unintended consequences, pointing to previous grants that ultimately flowed through to higher property prices.
Instead, he said developers were facing increasing red tape, approval delays and rising costs, which were discouraging new housing supply.
“In the absence of stock, demand exceeds supply,” he said.
Miron, a Co-Founder and Fund Manager of Msquared Capital, said the housing debate had become overly focused on tax policy while overlooking broader structural issues.
He argued that affordability challenges stemmed from a combination of factors, including planning constraints, supply shortages, migration levels and interest rates.
“No-one can be 100 per cent certain on the real reason for property prices is going up,” he said.
“The reason why property prices are higher is a combination of interest rates, lack of supply, migration, vacancy rates and maybe taxes play a role.”
Miron was critical of recent federal housing policy changes, warning they could reduce the number of new homes being built and further constrain supply that was even highlighted in the budget.
He also highlighted the importance of the property sector to the broader economy, noting that residential real estate and related industries employed more than one million Australians.
McNeice, who advises developers on sales strategy and market intelligence, said understanding buyers had become increasingly important as affordability pressures intensified.
While affordability remained a major consideration, she said today’s buyers were focused on value rather than simply price.
“People are looking for value for money,” she said.
She said buyers were increasingly evaluating factors such as transport connections, walkability, nearby amenities and flexible living spaces that could accommodate changing family needs.
“What infrastructure is going on? Can I walk to the shops? Can I meet people at the local cafe?” she said.
The panel also discussed the mounting pressures facing developers, with Elbanna arguing that many projects become financially unviable from the moment a site is purchased.
“The viability of a development happens at the moment the site is bought,” he said.
He said rising construction costs, higher interest rates and overly optimistic feasibility assumptions had left some developers exposed as market conditions changed.
While acknowledging the growing number of smaller and first-time developers entering the market, Elbanna said property development required expertise across finance, construction, marketing and legal disciplines.
“It is actually a business that requires a level of expertise,” he said.
Looking ahead, the panel agreed opportunities remained in the market despite current challenges.
Miron said property should continue to be viewed as a long-term investment and cautioned against trying to time short-term market movements.
McNeice said success would increasingly depend on identifying projects that genuinely met changing buyer expectations.
Elbanna said affordable housing remained achievable, but developers needed to deliver more than just homes.
“We can provide affordable housing in this country,” he said.
“But we’ve got to wrap that affordable housing with the things that people want.”
As Australia’s housing affordability debate intensifies, the panellists agreed on one point: without a meaningful increase in housing supply, demand-side measures alone are unlikely to solve the nation’s property challenges.
