What is "wikihouse"

WikiHouse is an open-source project for designing and building houses. It endeavours to democratise and simplify the construction of sustainable, resource-light dwellings. The project was initiated in the summer of 2011 by Alastair Parvin and Nick Ierodiaconou of 00, a London based strategy and design practice, in collaboration with Tav of Espians, James Arthur now with 00 and Steve Fisher of Momentum Engineering. It was launched at the Gwangju Design Biennale in Gwangju, South Korea. The project has since grown to include many chapters around the world.
