A Nissen Hut is a type of prefabricated structure originally designed for military use during World War I. It features a semi-cylindrical shape, which provides strength and stability while allowing for efficient use of space. Made from materials like corrugated metal, these huts were easy to transport and assemble, making them ideal for temporary housing and storage. After the war, Nissen Huts were repurposed for various civilian uses, including schools, community centers, and even homes. Their simple design and durability have made them a lasting symbol of wartime innovation and adaptability in architecture.
