The Quonset hut was introduced during WWII as a multiple-use, utilitarian, portable military building. Following the war, surplus Quonset huts became popular for use as farm and rural storage buildings, as well as for commercial storage.
Made of corrugated metal or fiberglass with interior wood framing, the Quonset hut is easily constructed and requires little maintenance. Along with the all-metal exterior siding and long rectangular plan, the Quonset hut is easily recognizable by an arched roof that extends to the ground, forming the side walls (although some rest on raised concrete foundation walls).
Doors are on the gable end, and in most early versions these consist of large sliding doors. These are attached to a track framework that extends out beyond the edges of the roof to allow for large openings. Overhead rolling doors are also used, as are pedestrian doors.
Quonset huts are still quite popular, and more-recent variants include a Gothic (pointed) arch shape and larger corrugations in the metal siding.
