My blog about metal building
Metal buildings were developed during World War II by the Navy Seabees to address the need for lightweight housing and storage units that could be assembled and torn down quickly in the battlefield. The design of these Quonset huts, as they came to be called, was modeled after and modified from the semi cylindrical design of the British Nissen hut into an insulated building with wooden linings and floorings. This metal buildings design, intended initially for use strictly as housing for troops and equipment, was itself subsequently modified to allow for more usable space as the buildings were also used as bakeries, isolation wards, dental offices and showers. They became so popular with the troops that some of them even purchased the surplus metal buildings for their personal housing after the war. Modern day metal buildings come in several different design kits.
