Sustainable House Day 2026: Real Homes & Real Ideas for Better Living
If you’re curious about sustainable home design in Australia but not quite sure what it actually looks or feels like in real life, Sustainable House Day is one of the best events on the calendar.
On Sunday 17 May 2026, homeowners across Australia will open their doors as part of Sustainable House Day — giving visitors the chance to walk through homes and see the practical ideas that make houses more efficient, affordable, and climate-ready.
Presented by Renew and Sanctuary Magazine, Sustainable House Day has grown over the past 25+ years into one of Australia’s largest community events focused on sustainable building design, passive solar homes, renewable energy and climate-resilient housing.
Opening our Doors: PdD on Sustainable House Day
In 2024, we were proud to open one of our projects to the public as part of Sustainable House Day. Our Solar Passive Home Design in Malua Bay gave visitors the chance to experience firsthand how solar orientation, natural ventilation and intentional architectural design can create a home that stays comfortable year-round while using far less energy.
The feedback was fantastic, and we enjoyed connecting with the community
This year we’re planning to participate again — but with a slightly different angle.
The Rise of the Sustainable Rental
The home we’re planning to open this year has been designed as a sustainable rental property, which opens up an interesting conversation..
Traditionally, rental homes haven’t been designed with sustainability in mind. The thinking has often been that if the tenant benefits from lower energy bills, the property owner doesn’t really see the return on that investment.
This situation is often referred to as the “split incentive” problem. It happens when the person paying for an improvement isn’t the one receiving the main financial benefit. In rental housing, that usually means the property owner pays for upgrades like solar panels, insulation or better glazing, while the tenant enjoys the lower energy bills and improved comfort. For a long time, this idea has slowed the adoption of sustainable design in rental homes — but the conversation is starting to change.
Because, in reality, good sustainable building design benefits everyone.
For tenants, the benefits are obvious. Solar power can significantly reduce or eliminate energy bills, leaving more room in the household budget for everyday living (and yes — paying rent).
A solar passive home, designed to capture winter sun and stay cool in summer, is also naturally more comfortable all year round. And when people feel comfortable in their home, they’re more likely to stay longer and take good care of the property.
For property owners, sustainable design can also make good financial sense. A home with solar panels and battery storage may not only generate rental income but could also export electricity back to the grid or participate in virtual power plant networks.
Then there’s resilience. Features like solar energy systems and rainwater tanks can help homes continue functioning during power outages or natural disasters — something many of us on the NSW South Coast understand all too well after the Black Summer Bushfires.
Good Design Makes Sustainability Simple
Events like Sustainable House Day are a great reminder that sustainable homes aren’t about futuristic technology or complicated systems. If you’re thinking about designing a new home, renovation or sustainable house, it’s a fantastic opportunity to see what’s possible and gather ideas from homes that are already doing it well.
We unpack these ideas with our clients to find what will be best suited to their needs. If you have questions, you can get in touch with us here.
We’re looking forward to opening the doors again this year and sharing ideas to create homes that are more comfortable, energy-efficient and better suited to Australia’s climate.
Homes that are not only good for the future — but great places to live right now.
