Nissen Huts Source https://en.wikipedia.org/wiki/Nissen_hut :
A Nissen hut is a prefabricated steel structure for military use, especially as barracks, made from a half-cylindrical skin of corrugated steel. Designed during the First World War by the American-born, British engineer and inventor Major Peter Norman Nissen, it was used also extensively during the Second World War and adapted to the similar Quonset hut in the United States.
