Simon Devitt describes the houses he likes to photograph as "self-assured, poetic and sustainable". And he's brought together 30 of his favourites in a book called Cape to Bluff. Some are intriguing because of the building technique, or the tricky terrain. Others picked themselves because of how they're future-proofed against sea level rise, or were inspired by an old goldminer's hut. The photographs are accompanied by interviews with the homes' architects, talking about the initial plans, and the head-scratching problems they needed to solve while they built.. Simon Devitt's been a professional photographer for more than 25 years, and he tells Lynn Freeman the landscape is just as much a part of the story as the buildings.
