About Sustainable House Day

Sustainable House Day returns on Sunday 17 May 2026, inviting people across Australia to step inside some of the country’s most inspiring homes and learn directly from the people who designed them, built them, and live in them.

For more than 20 years, Sustainable House Day has been helping Australians see what’s possible — from suburban retrofits and tiny homes to off-grid builds and community housing projects. Each year, hundreds of households open their doors to share real stories of sustainable living, proving that smarter design, lower bills, and climate resilience are achievable for everyone.

It’s neighbours inspiring neighbours: a national festival built on trust, generosity, and lived experience. The impact is clear — 70% of visitors say they’re inspired to make changes in their own homes within six months of attending.

Sustainable House Day is proudly presented by Renew, a national, not-for-profit organisation that inspires, enables, and advocates for people to live sustainably in their homes and communities. For more than 40 years, Renew has been a trusted source of independent advice on energy efficiency, sustainable building, electrification, and climate-ready housing — engaging more than 250,000 people every year through our magazines, events, and advocacy.

Together, we’re showing that climate action begins at home — one open door, one conversation, and one community at a time.
