A Quonset hut is a lightweight prefabricated structure of corrugated galvanized steel having a semicircular cross-section. The design was based on the Nissen hut developed by the British during World War I. The name comes from their site of first manufacture, Quonset Point, at the Davisville Naval Construction Battalion Center in Davisville (a village located within the town of North Kingstown, Rhode Island, USA).
In 1941 the United States Navy needed an all-purpose, lightweight building that could be shipped anywhere and assembled without skilled labor. The George A. Fuller construction company was selected to manufacture them. The first was produced within 60 days of contract award.
The original design was a 16 ft × 36 ft (5 m × 11 m) structure framed with steel members with an 8 ft (2.4 m) radius. The sides were corrugated steel sheets. The two ends were covered with plywood, which had doors and windows. The interior was insulated and had pressed wood lining and a wood floor. The building could be placed on concrete, onpilings, or directly on the ground with a wood floor.
