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.[1] 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.
