From carbon-neutral living and solar farms to shared electric vehicles and passive design, new development is reshaping how we live in Australia.
Demand for environmentally-geared new homes and buildings is on the rise, with sustainability becoming a cornerstone of property development globally.
Realestate.com.au's 2024 Property Seeker survey found that one in two (52%) Australian buyers said that sustainable property features and amenities are key criteria for them when buying a property, like solar energy, water tanks, skylights, double glazing and EV charging.
Similarly, the 2024 PropTrack Origin Australian Home Energy Report revealed that 56% of buyers are motivated by a desire to shrink their carbon footprint and minimise their environmental impact.
Along with updated government-led minimum energy efficiency requirements, green demand is being reflected in new builds and swiftly becoming the expected norm.
We are increasingly seeing approval for thoughtfully-designed, sustainably-focussed villages where residents can feel part of a connected, nature-filled community built to function well into the future.
But some are doing it better than others. Here are six Sydney projects standing out for their sustainability efforts.
