This clever take on a bach by Crosson Clarke Carnachan Architects sits atop two solid timber sleds that allow the beach house to be relocated as needed to cope with erosion of the site. The 430-square-foot retreat is located on the idyllic Coromandel Peninsula and sleeps a family of five. The textured macrocarpa cladding blends into the surrounding landscape, and it protects the home from the often harsh coastal environment.
