Sustainable House Day is back in 2026, and we can’t wait to open doors across the country once again.

Every Sustainable House Day starts the same way — with someone saying, “Come on in, I’ll show you what we did.”

From there, something special happens.

Visitors step inside beautiful, thoughtfully designed architectural homes, carefully retrofitted weatherboards, or small apartments made cooler for summer. They hear from renters who’ve cut their energy bills with clever upgrades, families who’ve undertaken all-electric renovations, and people rebuilding after floods who explain the choices that now help them sleep better at night.

The impact is powerful: 70% of past attendees report that they plan to make changes to their own homes within six months of visiting. 

Alongside open homes, communities run partner events — eco-village tours, expert panels, hands-on workshops, and local information sessions — creating spaces where people can connect and explore solutions together. 

Whether you’re opening your home or stepping inside someone else’s, Sustainable House Day 2026 is your chance to share, learn, and make change—together.

WHAT PEOPLE SAID

"Sustainable House Day was really worthwhile in demonstrating what is possible with retrofitting an older home. I'm now planning to swap out a gas cooktop for an efficient induction stove."
- Duncan
"It was interesting to meet home owners who have started or completed their sustainable journey. All were very generous with their time and knowledge, it was an inspiring day."
- Mathew
"It is so generous of the home owners to share their stories about their houses, and seeing it in person is so valuable - much more so than seeing a photo".
- Liz
"Home tours by the person that lives there is an authentic way to learn about the pros and cons of building and living in a passive, sustainable home. Incredibly informative!"
- Tania
"If you are planning a sustainable new build, or looking at renovating and bringing an older house up to date, then Sustainable House Day can’t be missed!"
- Lisa
