When considering a metal 30×40 garage there are two styles available. The design dictates the cost, to a large degree. A typical straight-wall (gable) style garage (see pic to right) with a peaked roof is one of the two main options, a ‘P-Model’ (with the P standing for peaked) Quonset Hut Garage (see pic to the left) being the other.
The ‘P-Model’ is an aesthetic extension of the original dome-shaped Quonset hut, with vertical sides and a peaked roof. Typically, a Quonset garage doesn’t require a complete concrete foundation slab, as the walls can be set on narrow concrete footings instead, such is its stability. However, in a garage environment, this is not recommended, and a full slab should be used.
When comparing prices for either type of steel garage compared to a traditionally constructed wooden garage the real saving is in the construction labor cost. Steel garages come as ‘steel building kits’ and are designed to be built by even novice Do-It-Yourselfers with only a hand full of basic tools. A 30×40 steel prefab garage can easily be self-built resulting in a saving of as much as $20,000!
