Archerfield Second World War Igloos Complex, Military heritage site in Archerfield, Australia.

The Archerfield Second World War Igloos Complex consists of three hangar buildings and one storage structure with timber frames and metal cladding at Archerfield Airport. The structures retain their original 1940s architectural features and function today as industrial spaces.

Built between 1943 and 1944 for the U.S. 81st Air Depot Group and U.S. 5th Air Force to perform aircraft repairs during World War II, these buildings represent a key moment in Australia's role in the Pacific war.

The structures show how Australia quickly developed practical solutions during wartime to meet military needs. They stand today as evidence of the working relationship between local builders and American forces.

The complex sits within an active airport grounds, so access is restricted and prior permission is required to visit. It is best to inquire in advance about visiting opportunities and plan accordingly.

A 1940s study of prefabricated wartime structures counted the Archerfield igloos among the longest clear-span buildings standing in Australia. The span was achieved with timber trusses rather than steel, and the three hangars and one store were run by Hastings Deering (Australia) Ltd and later Thiess Contractors Pty Ltd.
