What I say about metal building
The answer lay in constructing a lightweight shelter that could be readily shipped anywhere and did not require expert hands during assembly. In fact the building itself could be assembled just about anywhere, on concrete, iron pilings or even directly on the ground. The interiors could be used as needed and the open area could be concerted into residential units, military offices, storage structures or even be used as barracks. These buildings provided the US military with enhanced facilities and were a far cry from the inconvenient tenting on wooden bases that were usually used at that time. From its original usage as military structures, Quonset huts have seen many enhancements and other companies began to make variations to the model for other uses.
