The sides were made from corrugated steel sheets. The two ends were covered with plywood which had doors and windows. The inside was insulated and had pressed wood lining and a wood floor. The building could be placed on concrete, on pilings, or directly on the ground with a wood floor. The inside space was open, so it could be used for a variety of purposes. Some uses were as barracks, latrines, medical and dental offices, isolation wards, housing, and bakeries.
