Barndominium Cost Calculator & Price Guide

A barndominium is a barn-style building, usually steel-framed, that has been finished as a home. The shell goes up quickly and costs relatively little. Most of the money goes into the foundation, the utilities, and the interior, which are the same parts that make any house expensive.

Prices here come from published guides, with a check date of Oct 11, 2026. Several of the sources sell kits or buildings, so their figures can lean toward the products they offer. The tables name each source so you can weigh them.

The cost per square foot depends on how much of the work is included. Cost to Build House lists four stages. A shell kit alone, meaning the steel structure, is $20 – $35/sq ft. A dry-in kit with the exterior complete is $35 – $55/sq ft. A turnkey kit build, with the kit, assembly, and a standard interior, is $65 – $110/sq ft. A custom site-built barndominium is $100 – $160/sq ft. BuildingsGuide lists a materials-only steel shell at $15 – $25/sq ft.

The first two stages are not a finished home. A shell or dry-in kit leaves you with an empty building. You still need the foundation, plumbing, electrical, HVAC, insulation, and interior finishes before anyone can live in it, and those are the largest costs.

A square foot rate is easy to multiply, but a project total gives a more realistic picture. Cost to Build House gives totals for a 2,000 square foot home.

A turnkey kit build is listed at $130,000 – $220,000, and a custom site-built barndominium at $200,000 – $320,000. Mossy Oak Properties, a real estate company, gives a higher overall range.

Mossy Oak Properties lists $220,000 – $290,000. The gap with the kit totals may come from the home size, the level of finish, or the land and site work each source assumes. Land is a separate cost in almost every case, and none of these figures should be read as including it unless the source says so.

A kit price is only the start. Cost to Build House lists two big items that buyers sometimes overlook.

A foundation adds $15,000 – $40,000, and the interior finish adds $40,000 – $120,000. The interior range is wide because a basic finish and a high-end one are very different projects. Kitchens, bathrooms, flooring, and custom cabinets can swing the total more than anything else.

Most barndominiums sit on a concrete slab, though other foundations exist. Mossy Oak Properties and I Love Pole Buildings list per-square-foot add-ons.

A concrete slab runs $6 – $14/sq ft, and on-site assembly of a kit runs $10 – $15/sq ft. I Love Pole Buildings is a pole building company, so its assembly rate reflects its own kit work. Some buyers assemble kits themselves, but steel erection takes equipment and skill, so it usually calls for an experienced crew.

• Build type. A kit, a pole-barn frame, and a custom site-built structure all have different price levels.
• Size and layout. More square footage and a second story raise the cost. Complex rooflines add labor.
• Foundation. Slab design, soil conditions, and site prep change the price.
• Utilities. Well and septic, or connections to city services, can be a large expense on rural land.
• Interior finish. Flooring, cabinets, fixtures, and appliances range from basic to high end.
• Insulation. Metal buildings need careful insulation and moisture control to be comfortable to live in.
• Land and permits. The lot, zoning approval, and permit fees are separate from the building cost.
• Labor and location. Builder rates and material prices vary by region.

The shell is the cheaper part of a barndominium, because steel framing goes up fast and spans wide open spaces. The savings narrow once the interior is done, since the finishes cost about the same as in any house. Lenders, insurers, and appraisers can treat barndominiums differently from conventional homes, and financing may take more effort. Ask about both before you commit, and check with local building officials on codes, because rules for residential use of a metal building vary by county.

A kit gives you a defined price for the structure and a shorter timeline. A custom builder handles design and construction as one contract, and you get more design freedom. Kit buyers often still need to hire a general contractor for the foundation and the interior. Whichever route you take, get the scope in writing so you know who is responsible for each stage.
