Cost breakdown for a 60x100 metal building

Here is an expenditure breakdown for a standard 60x100 building with a concrete slab foundation and no interior build-out.

Cost factor Total cost (Avg.) Cost / square foot (Avg.)
Metal building kit $96,000 $16
Site prep & foundation $48,000 $8
Construction $42,000 $7
Accessories $12,000 $2
TOTAL $198,000 $33

Costs associated with each stage of construction are explored in the sections below.

  • Land cost estimates

    This is one of the most challenging estimates for any project, as land values vary widely from coast to coast.

    For a 6,000-square-foot building, you'll need a minimum of approximately 0.5 acres (22,000 sq ft) of suitable land. This will allow adequate access, parking, and setbacks (or yard space for residential builds).

    Based on current nationwide averages, here are some typical costs for a half-acre building plot.

    Land type Price range (0.5 acre)
    Agricultural / Farm $725 to $4,050
    Industrial / Commercial $25,000 to $200,000
    Residential $110,000 to $440,000


    Please note your land-to-building ratio will largely depend on local land use and zoning laws.


    On average, industrial land in the United States costs $117,951/acre, with prices ranging from $25,000 to $200,000 for a half-acre industrial plot.

    According to the most recent USDA figures, the national average for agricultural and farmland ranges from $1,450 to $8,100 per acre.

  • Building design costs

    For most projects, the design services of your chosen building supplier will enable you to customize the structure without requiring an architect.

    Alternatively, if a more elaborate design is required, you should budget for one or more of the following:

    • Architect fees at 7% to 15% of the construction cost.
    • Interior designer fees from $700 to $5,000.
    • For residential shop houses and barndominiums, floor plans can run from $750 for a stock plan to $2,000 for a fully customized one.
  • Cost of a 60x100 building kit

    The average cost for a pre-engineered 60 x 100 steel building kit package is $96,000.

    This will vary depending on where the building will be erected, as the frame must be engineered to meet local codes for wind, snow, and seismic activity. It will also fluctuate depending on the structure's required height.

    Our building kit packages sold by our suppliers are shipped with all the necessary components to construct your building, including:

    • Primary framing components (columns, beams, and rafters).
    • Secondary framing components (roof purlins, wall girts, struts, and bracing).
    • Metal wall and roof sheeting panels.
    • Fasteners, sealants, and an erection manual.

    Roof-only steel buildings are also an option and are typically used as large hay barns, outdoor gymnasiums, carport parking structures, and horse riding arenas.

    Such structures can be 25-35% less costly than a fully enclosed building because they don't require wall girts or wall panels. The average cost for a roof-only 6,000-square-foot building is $138,000.


  • Site prep and foundation costs

    Before a foundation can be installed, the site must be cleared and prepared for construction.

    Site prep costs vary widely. A 6,000-square-foot site can range from $3,800 to $26,000, broken out as follows:

    • Soil testing and analysis $700 to $1,800.
    • Site clearing $780 to $12,000 ($0.13 - $2/sq ft).
    • Land leveling and grading $2,400 to $12,000 ($0.4 - $2/sq ft).

    Costs will be dictated by:

    • The condition of the site (removal of existing structures, trees, etc.).
    • The amount of grading required.
    • Soil quality.

    A concrete foundation for a 60x100 metal building costs from $6,000 to $68,000.

    Depending on the end use of your 60x100 steel building, you may require a concrete slab foundation.

    If you plan to store heavy machinery or equipment, then a six-inch foundation is required to handle the additional load. A four-inch foundation will suffice for everything else.

    However, most dirt-floor agricultural buildings only require concrete piers to support the structure. The size of those depends on soil type and the weight of your building.

    The number of piers required for a typical 60x100 building (with 25-foot bay spacing) is 12 to 16.

    All new builds (irrespective of end use) require concrete piers to anchor the steel columns to the ground.

    The cost of an engineer-designed and stamped foundation plan must also be factored in. These typically run anywhere from $3,000 to $6,000, depending on complexity and type.

    Foundation Type Cost per Square Foot Total Cost
    Slab foundation (4”) $5 - $7 $30,000 - $42,000
    Slab foundation (6”) $8 - $10 $48,000 - $60,000
    Concrete piers (min. 12) *

    Min $500 (per pier)

    $6,000 - $8,000

    * This is a rough estimate. A structural engineer will advise on the required number of piers based on calculations specific to your building and location.

  • Construction costs

    Constructing a metal building costs between $5 and $10 per sq. ft., so $30,000 to $60,000 for a  60x100 metal building (based on constructing a standard rectangular building with no complex design upgrades).

    If opting to self-build, be sure to hire a company with plenty of experience working with pre-engineered buildings (not all companies do).

    For a building of this size, we strongly recommend hiring a General Contractor (GC). The GC will hire, manage, and oversee all the necessary subcontractors and ensure the project runs smoothly. GCs typically charge from 10 to 20% of the construction cost.


  • Custom accessory costs

    A standard building must be customized to suit your intended application. Some of the more popular custom options include:

    Doors and windows

    During the design stage, the number, size, and placement of doors and windows must be specified. Framed openings are then engineered at the factory to accommodate them.

    Opening Type Framed Opening Cost Door Cost Total Cost
    Commercial garage door $400 - $800 $900 - $4,000 $1,300 - $4,800
    Commercial roll-up door $400 - $800 $1,200 - $5,000 $1,600 - $5,800
    Personnel door $300 - $600 $450 - $850 $750 - $1,450
    Windows (4’x3’) $200 - $400 $200 - $700 $400 - $1,100


    framed opening for pre-engineered (red iron) building

    Framed openings


    When it comes to insulation, there are two primary options: closed-cell spray polyurethane foam (SPF) and fiberglass blanket (or batts).

    The cost for 2-inch (R-12) SPF insulation is $18,800 and $33,750 (based on an installed price of $2.5 - $4.5/sq ft), while 4-inch (R-13) fiberglass blankets will cost $5,300 to $18,750 (based on an installed price of $0.7 - $2.5/sq ft).

    We recommend SPF insulation for its numerous benefits, including:

    • Higher R-values with less material.
    • Exceptional thermal barrier due to air-tight seal.
    • Increased structural integrity and building rigidity.
    • Superior moisture resistance and waterproofing capabilities.
    • Greater durability than other insulation types.

    Additional custom features/costs include:

    • Lean-to extensions from $24 to $26 per sq ft.
    • Door canopies (awnings) from $850 to $2800
    • Ridge vents (installed) from $350 to $750 (9” x 10’).
    • Turbine vents (installed) from $150 to $300 per 16” vent.
    • Cupolas from $500 to $1,200 per 3’x3’ cupola.
    • Gutters and downspouts spaced at 25’) from $2,520 to $5,400 (based on an average of $7 - $15 per linear ft).
  • Utility installation costs

    Depending on the location, you will either tie into existing utilities or run new service lines to the site.

    • Electricity hookup will cost $10 to $25 per foot (from the nearest line).
    • Utility pole installation will cost from $350 for a temporary pole to $10,000 for a permanent one with 500 feet of underground wiring, transformer, and meter box.
    • Water lines will run anywhere from $1,200 to $10,000 (the nationwide average is approximately $3,750).
    • Drilling a water well with a completely installed system will cost between $5,000 to $10,000.
    • Sewer lines will cost an average of $3,000 to $6,000.
    • Septic installation can run anywhere from $3,500 to $12,000.

  • Interior build-out costs

    If required, the interior of a pre-engineered building can be framed and finished much like a traditional building. Interior rooms and partitioned areas are framed with either wood or steel studs. The final expenses for the interior build-out will be dictated by square footage and the level of finish work.


    • Interior framing will range from $20 to $30 per square foot for steel studs and approximately $8 to $16 per square foot for traditional wood framing.
    • Interior finishing costs for drywall, paint, and trim will fall between $5 to $9 per square foot.
    • Electrical wiring for outlets and lighting will cost $3 to $7 per square foot.
    • Plumbing costs will fall between $4 and $6 per square foot.

Why buy a 60x100 metal building?

  1. Faster occupancy. Compared to traditional construction, which takes anywhere from 4 to 12 months to build on average, 60x100 steel buildings can be completed in under 3 months. That’s up to one-third of construction time saved.
  2. Ability to span long distances. Concrete block and wood construction require heavy engineering and need lots of fabrication time. In comparison, steel buildings can span up to 300 feet with less material and higher durability.
  3. Cost efficiency. Prefab 60x100 buildings require less labor and materials compared to concrete and wood-framed buildings. This efficiency makes them 10% to 30% less expensive than conventional construction options.
  4. Flexibility of expansion. Due to modular, bolt-together construction, you can add as many additional 20- to 30-foot bays to an existing  building as needed.
  5. Low maintenance. Wood buildings are prone to water damage, mold, and rot, along with warping. These reduce air conditioning efficiency and add to overall maintenance costs. In contrast, steel buildings are easy to clean and resistant to fading, discoloration, and corrosion.
  6. Single-source responsibility. Since a single party is responsible for the entire building, you don’t have to keep track of various suppliers or worry about construction delays.

How to build a 60x100 metal building

With a prefabricated 60' x 100' metal building kit, you can have a structure ready for occupancy within 2 to 4 months.

This section will consider every step of the building process — from planning to maintenance.


  • Planning and project scoping

    Planning a successful prefab building project demands attention to detail and strategic decision-making.

    Determine requirements. Begin by defining every aspect of the building's intended purpose and carefully consider your space and layout needs.

    Decide on a budget. A well-planned budget is crucial to a project of this size. You must account for the building kit, permits, foundation, construction, insulation, finishing, and any accessories like doors and windows.

    Determine height requirements. Choose a height based on usage. Remember, the height is measured to the eave. Standard buildings are limited to 30 feet.

    Some common 60x100 building heights, based on use-case, include:

    Building type Height range
    Warehouse 10 - 30 ft
    Shop 10 - 16 ft
    Barn 10 - 20 ft
    Home 9 - 18 ft

    Plan your framed openings. Standard kits offer one overhead and one walk door opening. Plan and budget for any additional openings as they require engineering and are difficult to add later.

    Site selection and surveying. Confirm the construction suitability of your site. This includes checking for setbacks, utility access, ground support capacity, easements, and creating a site plan with a local structural engineer's help.

    Apply for permits. When applying for permits, submit your property plans, foundation plans, and building blueprints to the local building department. Note that some buildings, depending on their purpose, may be exempt from permits.

    Engage a structural engineer. This is not typically required for a standard rectangular building without special features. However, for a pre-engineered building with customized designs or complex foundations, a licensed structural engineer experienced with PEMBs is recommended.

    Financing. Finally, explore construction loans, home improvement loans, or agricultural property financing if you need further funding. Before applying for a loan, look at several lenders that understand financing steel buildings. Be aware that not all lenders provide financing for pre-engineered buildings.

  • Design your 60x100 building

    After inspecting the site and obtaining the necessary permits, it's time to design your building.

    Your supplier can assist in configuring your building without the need to hire an architect. Popular design and customization options include:

    • Roof profile and pitch
    • Building eave height
    • Placement and size of doors and windows
    • Siding and roofing materials
    • Building color scheme
    • “Roof-only” design (if walls are not required)
    • Roof extensions and lean-to additions
    • Door canopies/awnings
    • Skylights and roof vents

    The supplier will also provide drawings and blueprints for the general contractor and the construction permit application.

    Roof style and pitch.

    The style and pitch of the roof will depend on the building's intended function. Most buildings of this size will have either a single slope or gable roofline with a low 1:12 or 2:12 pitch. Gambrel and monitor roof options are also available as a custom option.

    Floor plan: For residential use, consider hiring a designer. Alternatively, search for 60x100 floor plans online, selecting and adapting the best to your needs on graph paper.

    Customizations: Play with color combinations and consider different door types like roll-up or bi-fold. Add structural elements like lean-tos or door canopies. While kits come with metal siding, options like faux brick or stucco are also available.

    To learn more about steel building design and customization options, visit our design center. 

  • Order your building kit

    Finalize the design and layout, then request bids using our quote form. We connect you with four steel building suppliers, you then choose the one that best fits your project.

    After choosing a supplier, the process includes:

    Deposit. Pay a 20-30% deposit to start engineering and design.

    Contract Signing. Finalize a contract with the supplier for fabrication.

    Engineering and foundation plans. Receive designs stamped by a state-licensed engineer within 2 to 3 weeks. Check for extra charges for foundation plans.

    Construction Preparation. With plans in hand, get construction quotes and start permitting with local authorities.

  • Pre-construction

    Use the 2- to 4-month kit waiting period to prepare the site. With a 6,000-square-foot building, site prep can be a major project itself.

    Groundwork. Grade the site, prepare soil, install utilities, and create access routes for construction vehicles and storage of the building kit components.

    Foundation Laying. Conduct a precise survey for column placement, set foundation formwork, and perform a detailed survey for accurate anchor bolt placement.

    Customization. Engage a structural engineer if your design is customized or the foundation is complex.

  • Building construction

    Get equipment ready for kit delivery. The construction process involves erecting columns, framing, rafters, wall girts, and roof purlins per the supplied construction manual.

    Designate areas for specific materials. For instance, position columns close to their final locations after materials are staged and checked.

    For a project this size, we strongly recommend engaging professional steel erectors.

    Regarding the actual construction, you have two options:

    1. Self-build. You act as the general contractor, hire a crew, and manage the construction directly.
    2. Hire a general contractor (GC). This option offers convenience and efficiency and will speed up construction.
  • Interior finish work and inspection

    Work on the building's interior depends on its intended use and local climate. The kit includes only the shell (steel framing, roofing, and siding panels).

    Wiring, plumbing, and finishing. Arrange for local subcontractors to handle wiring, lighting, heating, plumbing, flooring, and interior framing.

    Insulation. Invest in insulation (fiberglass or spray foam) for energy savings and climate control, condensation prevention, and soundproofing. These materials can be sourced from the kit supplier or locally.

    Interior Framing. To create interior rooms or floors based on the building's use, hire a local framing company. Choose between light-gauge steel studs or 2x4 lumber.

    Final Inspection. Ensure all minor issues are resolved. The building must comply with the design drawings and any special directives. This step includes inspections by architects, engineers, and the local building department. A successful inspection results in a Certificate of Occupancy, indicating the building is safe for use.

  • Building maintenance

    Regular maintenance is crucial for your building's longevity, especially to mitigate moisture, structural damage, and ground shifts. The checklist includes:

    • Regular monitoring. Check for surface damage to prevent rust. In humid areas, conduct annual inspections for mold, rot, and water issues.
    • Exterior maintenance. To promote air circulation and prevent moisture buildup, remove snow from the roof. This also avoids stress on the steel roofing panels and framing.
    • Insulation check. Inspect insulation regularly for moisture, damage, or exposure to prevent rust and mold.
    • Periodically clean the building to remove dirt and grime and to prevent surface tarnish, rust, or mold.
    • Annual checks: Conduct yearly inspections for scratches, dings, and abrasions to address minor issues before they worsen.

Common pitfalls to avoid when erecting a 60x100 metal building

While prefab-engineered buildings offer cost-effective, durable, and fast construction, it is crucial to pay attention to certain details to guarantee the project runs smoothly and the finished building meets your needs.

  • Inadequate planning. Don’t rush the planning stage. Ensure all design aspects have been considered to prevent costly change orders, overruns, and missed deadlines.
  • Overlooking future needs. Plan for prospective expansion. It is more cost-efficient to order “expandable end walls” when placing your order than to reengineer the building later.
  • Ignoring local building codes and regulations. Begin communication early with local building authorities to avoid any zoning or code violations and potential legal complications.
  • Overlooking the importance of the foundation. The main reason for a steel-framed building failing is an inadequate foundation. We can’t stress this enough! It is vital to have a certified structural engineer design the foundation. Cutting corners when selecting a concrete installation company is also not advised.
  • Hiring inexperienced contractors.: As with the previous point, stringently vet the construction company and ensure they have extensive experience with pre-engineered builds.
  • Insulation and ventilation oversight. Proper insulation and ventilation are key to maintaining a building's energy efficiency. Failure to do so can lead to heat and moisture accumulation, which can potentially damage the structure.
  • Purchasing purely on cost. Prices and quality vary in the PEMB market. Some unscrupulous suppliers push for quick sales. Don’t be tempted to rush into ordering a building that will not be suitable for your needs. Be sure to get detailed written quotes from at least three suppliers, then carefully compare.

Note: While the above guide provides general recommendations and details, always consult a structural engineer to ensure your structure adheres to all local building codes and environmental considerations.

Common Questions

  • Are steel buildings energy-efficient?

    Yes, they are. Unlike wooden structures that can develop gaps over time, steel buildings don’t warp or settle, thus providing an air-tight building envelope. Their energy efficiency can also be improved with reflective metal roofs (cool roofs) that decrease cooling costs by up to 40%. These also allow for effective temperature regulation. Utilizing insulated panels and specialized systems also plays a role in maximizing energy performance.

  • Should I insulate my building?

    Whether you need insulation depends on how you'll use the space. If you're housing heat-sensitive equipment or will have people or animals inside, consider the thermal conductivity of metal. The building may experience severe temperature fluctuations without insulation, becoming excessively cold in winter and uncomfortably hot in summer.

  • How long do metal building kits last?

    They typically last 50 to 100 years, with variations depending on material quality, environmental conditions, maintenance, construction quality, and usage. Advances in technology continue to enhance the durability and lifespan of PEMBs. Regular maintenance and high-quality materials can significantly extend their longevity.

  • Do I need building permits to build a steel structure?

    Generally, yes, you’ll need a building permit to get a metal building approved by your local building department. However, you might be exempt if the structure is for farming purposes. Before starting a project be sure to consult with your local building department.

  • How many square feet is a 60x100 building?

    A 60x100 building is theoretically 6,000 square feet. However, the actual usable space can vary depending on the intended application. Structures with internal rooms and partitions will have less usable floor space.
