A Nissen hut is a prefabricated steel structure originally for military use, especially as barracks, made from a 210° portion of a cylindrical skin of corrugated iron. It was designed during the First World War by the Canadian-American-British engineer and inventor Major Peter Norman Nissen. It was used also extensively during the Second World War and was adapted as the similar Quonset hut in the United States.

Barracks are buildings used to accommodate military personnel. The English word originates from the 17th century via French and Italian from an old Spanish word barraca 'soldier's tent', but today barracks are usually permanent buildings. The word may apply to separate housing blocks or to complete complexes, and the plural form often refers to a single structure and may be singular in construction.
