Quick answer
A finished barndominium typically costs $80–$120 per square foot (range $65–$160), excluding land. A metal kit alone is $20–$35/sq ft and an erected shell $30–$50/sq ft. A 2,000 sq ft finished barndo usually lands around $180,000–$290,000 including $20k–$50k of site work — often 15–25% less than a comparable stick-built home.
What the Barndominium Cost Calculator does
Choose the size, how finished you want it and whether to include an attached shop. The calculator applies 2026 price ranges per square foot for each stage, adds typical site work, adjusts for your area and compares the result with a traditional build.
The shell is usually only 30–40% of the final cost — insulation (spray foam), HVAC, plumbing, electrical and interior finishes make up the rest, so be wary of quotes that only cover the kit.
The formula
Cost = living sq ft × price per sq ft (by finish level) + shop sq ft × $30–$50 + site work, × local price factor.
Worked example
1,800 sq ft finished + 600 sq ft shop, average area: $144k–$216k + $18k–$30k + $20k–$50k = $182,000–$296,000.

Frequently asked questions
Is a barndominium cheaper than a house?
Usually 15–25% cheaper per square foot once finished — not the 50% sometimes claimed, because insulation and HVAC add up.
What does a barndominium kit include?
Typically the steel frame, roof and wall panels, trim and fasteners — not the foundation, labor, insulation or interior.
Can I get a mortgage for a barndominium?
Yes, but it can be harder; construction loans and lenders familiar with post-frame homes are common routes.
How long does it take to build?
Often 6–12 months for a finished barndominium, faster than many traditional builds.
