We've been given some new photos of Delta Shelter, a weekend cabin in Washington State, USA, by Tom Kundig of Olson Sundberg Kundig Allen Architects.
The 1000-square-foot cabin is made of steel and is raised above a floodplain in a wooded valley.
The 10' by 18' steel shutters can all be opened or closed simultaneously by means of a hand crank, allowing the cabin to be quickly sealed upon departure.
Accommodation is over three floors, with the living room/kitchen at the top.
