    Our 40 x 40 metal building delivers 1,600 sq ft of clear-span interior space for a four-car garage with a shop, a small warehouse or auto shop, or a three-bedroom barndominium or shop house with an attached double garage.

    Each building package includes pre-cut steel I-beam primary framing, secondary purlins and girts, 26 ga PBR roof and wall panels, and a complete trim package. The number, width, and height of framed door openings are fully customizable, allowing you to configure wide front-facing bays, side-access doors, or a mix of vehicle and personnel doors. With a 40' wide metal building, you get two spacious 20' wide bays that can be configured to suit your specific access requirements.

    Allow at least 2 ft of clearance between the top of the tallest door and the eave height; for example, a 12 ft-tall RV door needs a 14 ft eave.

    Unlike light-gauge tubular buildings and pole barns, our trussless red iron PEMBs are custom-engineered to meet or exceed local codes for snow, wind, and seismic loads, giving a clean permitting path for barndominiums and other occupied uses while adding long-term property value and reduced insurance premiums.

    At 1,600 square feet, a 40×40 building package is often DIY friendly for experienced builders or can be erected by a local steel crew if you prefer turnkey installation. The trussless roof design makes it simple to insulate, finish interiors, add a mezzanine loft over part of the floor, or hang heavy equipment or cranes.

Frequently asked questions

  • How much does a 40x40 metal building with slab cost?

    The average installed cost of a 40-by-40 metal building is $38,400 to $60,800. This includes an average cost of $28,000 for the steel building package, $ 9,600 for the concrete slab foundation, and $12,000 for construction. Your budget should also account for doors, windows, and insulation, if necessary.

    These costs vary depending on the job site location, local labor rates, and the building's final design. Please use our quote request form for accurate written quotes from four competing suppliers, or for a quick 40×40 steel building price estimate, see our metal building prices page.

  • Do I need a building permit for a steel building?

    Yes. Unless you are on exempt farmland, you will likely need a permit. Larger buildings or those intended for commercial occupancy often face stricter regulations.

    Checklist for success:

    Check Zoning First: Ensure your land is zoned for this type of structure before paying for permits.

    Get Certified Plans: Building officials require certified plans for the structure and foundation. Your building supplier will provide building plans, and your structural engineer will provide the foundation plan

    Hire a Surveyor: You will need an official site plan created by a licensed professional.

    Stick to the Plan: Changes made during construction require re-permitting. Stick to the certified blueprints to avoid additional fees.

  • What are my options for installation?

    When it comes to erecting your 40x40 metal building, you have three main options, these include:

    Do-it-yourself (DIY). We only advise going this route for smaller buildings (under 2,000 square feet) and for those with previous construction experience.

    Self-manage. With a self-managed project, you are responsible for hiring and managing the various sub-trades, including the concrete company for the foundation, the steel erectors to construct the building, and plumbers and electricians.

    Hire a General Contractor (GC). For a completely hands-off option, you may want to consider hiring a GC who will manage the entire project on your behalf, from pulling permits and installation to the final inspection. Expect to pay 10-20% for a GC's services.

  • What financing options are available for metal buildings?

    Here are the most common options for financing a new building.

    • Consider home improvement loans for smaller projects, such as small metal shop buildings, standard garages, or shops.
    • Home Equity Line of Credit (HELOC) is more flexible and has competitive rates, but you must use your home as collateral.
    • Construction loans are ideal for larger residential and commercial projects.
    • Farm credit for agricultural and farm building projects is the final option.

  • How many cars can fit in a 40x40 garage?

    A 40x40 garage (1,600 sq. ft.) typically holds 3 to 4 cars for comfortable daily use, leaving ample room for a workshop.

    By parking tandem (one behind another), you can store 6 to 8 vehicles. For tight, long-term storage without aisle space, the maximum capacity is roughly 10 cars.
