Barndominium Kits: What the Steel Really Costs
The barndominium boom is really a steel-building story: a clear-span metal shell with a house built inside it. The shell is the cheap part — the finish-out is where budgets live or die. Here's the honest 2026 math.
What the steel shell costs
| Barndo shell (shell only, erected) | Typical 2026 range |
|---|---|
| 40×60 (2,400 sq ft) | $45,000 – $70,000 |
| 40×75 (3,000 sq ft) | $55,000 – $85,000 |
| 50×100 (5,000 sq ft, shop + home) | $85,000 – $130,000 |
Shell scope: engineered frame, sheeting, insulation-ready, residential door/window openings framed, slab included. That's roughly $19–$28/sq ft in 2026.
The finish-out is the real budget
Interior build-out — framing, plumbing, electrical, HVAC, kitchen, baths, flooring — runs $60–$120+ per square foot of living space, the same as any custom home interior. A 2,400 sq ft barndo with 1,600 sq ft of living space typically totals $175,000–$300,000 all-in, land excluded.
Why start with the shell design
Window and door placement, porch framing, and eave height are 10× cheaper decided before the steel is engineered than after it's delivered. Our free 3D designer lets you place every opening and see the shell take shape before anything is ordered.

How much does a barndominium kit cost in 2026?
Steel shell kits for typical barndo sizes run $30,000–$90,000 depending on footprint and spec; erected shells with slab run $19–$28/sq ft. Interior finish-out adds $60–$120+ per living square foot.
Is a barndominium cheaper than a regular house?
The shell is dramatically cheaper per square foot than conventional framing, and you can enclose bonus shop space almost for free. Finished living areas cost about the same as any custom home — the savings are in the envelope and the shop.
Can I finance a barndominium?
Yes — construction-to-perm loans that cover steel shells are widely available now, though some lenders still want a builder of record. See our metal building financing guide.
