40x80 Metal Building
A 40x80 metal building provides 3,200 square feet of clear-span space — ideal for a large commercial shop, a small covered riding arena, warehouse storage, or an estate-scale barndominium with room to spare. The 80-foot length supports long pull-through bays.

What's in the $59,900 starting price?
That figure is for a base open-web-truss building kit, delivered to your site — engineered trusses, secondary framing, steel sheeting, fasteners, and stamped engineered plans, all backed by a 50-year structural warranty. Site prep, foundation, assembly, insulation, doors, windows, and any residential or barndominium finishing are additional. A fully finished 40x80barndominium runs significantly more than the base kit. Your exact price depends on your county's wind and snow loads, eave height, and the options you choose — which is why every quote is custom.
