There are two main types of metal buildings you can construct using a kit: Quonset huts and rigid frame buildings.
A rigid frame structure includes sturdy steel framing with minimal internal obstructions. If you want clear span architecture, you will find that rigid frame buildings are ideal for serving as warehouses, barns, churches and residences.
A Quonset hut consists of an arch of metal with walls on either end. The original application of Quonset huts was in the military in WWII. Soldiers needed to be able to build structures quickly, even if they had no specialized tools on hand and minimal building experience.
Like rigid frame buildings, Quonset huts are suitable for a wide range of applications. The exact cost depends on a variety of factors, including the size of the structure, its shape, insulation, windows and doors, finishing options, and more.
