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

Homes across Australia throw open their doors, sharing real stories, practical ideas, and the lessons learned along the way.

Sustainable House Day is about neighbours inspiring neighbours. It’s about seeing what’s possible when people make changes in their own homes — whether that’s electrification, passive design, renewable energy, water saving, climate resilience, renovations, apartments, or tiny homes.

These aren’t display homes or perfect homes. They’re real homes, opened generously by the people who live in them.

Because climate action starts at home, and some of the most powerful conversations happen around a kitchen table, in a backyard, or standing beside a hot water system asking, “So how does this actually work?”
