Dymaxion deployment unit

Structure designed by Buckminster Fuller

A Dymaxion deployment unit (DDU) or Dymaxion House, is a structure designed in 1940 by Buckminster Fuller consisting of a 20-foot circular hut constructed of corrugated steel looking much like a yurt or the top of a metal silo. The interior was insulated and finished with wallboard, portholes and a door. The dome-like ceiling has a hole in the top and a cap for ventilation.
