24x40 Metal Building
A 24x40 metal building offers 960 square feet — a deep, versatile footprint that works as a three-bay garage, a workshop with a parking bay, or a small commercial shop. The extra length over a 24x30 makes room for a vehicle lift or a dedicated work area without crowding your parking.

What's in the $24,900 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 24x40barndominium 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.
