Metal building, a great post
The sides of the main unit was cut out to include the doors and windows in wooden ply, and the thermal protected central area had wooden flooring. The very idea of this type of provisional housing facilities increased in use post 1941 when the US Navy needed reliable shelters for its military bases. The answer lay in constructing a lightweight shelter that could be readily shipped anywhere and did not require expert hands during assembly. The structures needed no special flooring to assemble on and could be placed as easily on the ground as on steel pilings or hard concrete floors. The interior space is an open area allowing maximum flexibility, which means the facility could be used as housing, office or medical space, military storage units or even barracks.
