In Sanctuary 66, we celebrate Sustainable House Day, spotlighting terrific new builds and extensions from Perth to Sydney and from Tassie to Queensland that are participating in the perennially popular event. We revisit a Canberra apartment transformed after being part of our Design Workshop program. There’s a rundown on alternatives to good old plasterboard for interior wall linings, and we meet the inspirational teams behind the Sustainable Builders Alliance and the game-changer Powerhaus energy rating tool. Jacqui Hagen contributes her gardening tips for renters – including relocating your garden – plus much more.
