Brent Dunn is an architect whose home and studio are located in the bush south of Sydney. There’s no fire there for now. Dunn just returned from an annual camping trip that, this year, seemed apocalyptic: Wind as hot as a hairdryer’s blast, a thunderstorm raining down wet ash, and a smokey rainbow that stretched across the sky. We caught up with him at his studio, where tropical birds fleeing from burned rainforest have been gathering in the garden.
