[2][3] The Twynham hut was intended for similar use, as a temporary accommodation structure in field conditions and emergency situations.
[3] The standard hut was 64 feet (20 m) long but it could also be constructed in half (32-foot, 9.8 m) and quarter (16-foot, 4.9 m) lengths, with the front bay remaining unchanged.
[8] A heavier duty version was constructed for use in the tropics, which weighed 0.85 long tons (0.86 t) more and required a larger foundation of 14.6 cubic yards (11.2 m3).
[4] A Royal Engineers report of 1966 regarded the Twynham hut as well suited for long-term use in the tropics, but recommended that the Nissen, still held in large quantities in army stores, be preferred in temperate climates.
Because British forces were being withdrawn from positions across the island to the Sovereign Base Areas of Akrotiri and Dhekelia additional accommodation was required at these locations.
[14] Lieutenant-colonel Gus Sinclair recovered 85 Twynham huts from an abandoned British base in the aftermath of the September 1969 Libyan coup d'état.
[15] The Twynham huts were still in use in 1982 when they formed part of the aircrew accommodation at Wideawake airfield on Ascension Island during the Falklands War.
