Metal Home Kits Prices

The cost of metal home kits averages $50,000, ranging from $20,000 to $90,000. The total runs $10 to $50 per square foot, depending on the size of the structure and what’s included in the kit. Basic models around 1,000 square feet are usually the least expensive.

While you might see metal home kits as low as $5,000, it’s important to get the details before buying. Some products provide only the outer shell, which is similar to what you’d get for a shed.

Metal homes are an affordable choice for budget-minded people who already own the lot. Most materials in these kits are easy to recycle, which means that they are more environmentally-friendly, too.

“Metal house construction is a popular choice for ‘accessory dwelling units’,” says Bob Tschudi, Angi Expert Review Board member and general contractor in Raleigh, NC. “An ADU is built on the same lot as the primary dwelling, and can be used as an office or studio, a rental unit, or just an extra guest suite.”

Be sure to check with local ordinances about size and style requirements for accessory dwelling units, as some municipalities have very strict guidelines.

Barndominium Kits Prices

Barndominium kits cost $5,000 to $70,000, depending on square footage and the style. For example, a 2,000-square-foot barn-style home may have a covered porch or large windows, which runs more.

Barndominiums are a popular style among metal houses. They tend to have an open layout inside, and usually don’t include a garage.

Other Steel House Kit Price Considerations

Once you’ve bought the kit, you’ll still need several important services before you can live in it. Some are necessary, like a foundation or plumbing. Others, like new siding, may be optional.

Foundation$4,000 - $12,500
Plumbing$400 - $1,900
Septic Tank$3,200 - 9,500
A/C$3,800 - $7,300
Furnace$2,600 - $6,200
Siding$6,000 - $16,000
Permits$400 - $2,000
Contractor$3,500 - $45,000

Building a Foundation

The price to build a foundation ranges from $4,000 to $12,500, depending on the size and if you’re making space for a basement. It’s necessary to give your home a permanent installation.

Installing Plumbing

The cost to install plumbing pipes is $400 to $1,900, but may run more for larger homes. You’ll need it if you want to have a functional kitchen or bathroom.

Installing a Septic Tank

Installing a septic tank costs $3,200 to $9,500, depending on the type of system. You may need this if you’re building the kit on land that doesn’t have a sewer line nearby.

Installing HVAC

Heating, ventilation and cooling may be required, depending on where you live and how you plan to use the building. Prepare to pay extra to have a pro put in these systems:

Upgrading Siding

Upgrading siding costs $6,000 to $16,000, depending on the material and square footage. You may want to do this project if the exterior panels of the kit are plain or less likely to last in your climate.

Building Permits

Building permit prices range from $400 to $2,000, related to where you live and the project. Installing a new building on your property usually requires a permit.

General Contractor

The cost to hire a construction manager runs $3,500 to $45,000. This pro typically fills the role of a general contractor, to bring in subcontractors who can manage the various aspects of installation you’ll need to build a home.

DIY Metal Building Kit Assembly vs. Hiring a Pro

It’s tempting to DIY a metal home kit, but you should avoid this unless you’re very skilled at DIY construction projects. This isn’t the same as assembling a big shed, because it must be a livable space.

A professional can assess the kit, determine if you need additional services, and assemble the structure in less time. If you’re ready to look for general contractors near you, remember to request estimates from three pros before you make a choice.
