Happy Haus by Donovan Hill
Via @ArchDaily, a prefab house in Australia made using "the same systems any ordinary house is built from. The Happy Haus concept has its own form of benign innovation. It has no nifty gadgets, it does not even fit into a kit. It is entirely reconstructed using systems ideally suited to easy installation and maintenance ie; the same systems any ordinary house is built from." More at Donovan Hill.
