Barndominium Cost Calculator
A 2,000 sq ft barndominium with mid-range finishes costs about $336,960 nationally — $168/sq ft of finished living area, land excluded. That is roughly 10.4% below a comparable stick-built home, because the shell only accounts for about 29% of a conventional build. The kitchen, the mechanicals and the concrete cost the same either way.
Finished space only. Unconditioned shop or garage area costs far less per square foot — price it separately.
Quality materials throughout
The shell replaces roughly 29% of a conventional build — the framing and exterior envelope. Everything else is priced from Texas's own labour and material costs, because a kitchen costs what a kitchen costs regardless of what holds the roof up.
Why barndominiums save less than people expect
The pitch is that a metal building is far cheaper than a house. The shell genuinely is. But a finished barndominium is a house that happens to sit inside a post-frame structure, and most of what makes a house expensive is not the frame.
Using this site's own line-item breakdown, framing and the exterior envelope together are 29% of a mid-range build. That is the only part a shell package replaces. The other 71% — foundation, plumbing, electrical, HVAC, insulation, drywall, cabinets, flooring, fixtures, permits, contractor overhead — is identical work at identical local labour rates.
| Component | Share of a mid-range build | Changed by going barndominium? |
|---|---|---|
| Framing & exterior envelope | 29% | Replaced by the shell |
| Foundation & slab | 10% | No — often larger |
| Plumbing, electrical, HVAC | 18% | No |
| Insulation & drywall | 7% | No — often more, large spans |
| Interior finish & fixtures | 27% | No |
| Site work, permits, overhead | 9% | No |
This is also why a high-end barndominium barely saves anything. Push the interior up a tier and the fixed trades grow while the shell stays the same, so the percentage saving shrinks. Try it in the calculator above — switch the finish level and watch the saving move.
Barndominium cost by building size
Barndominiums are shopped by dimensions, so here are the common ones at national average costs with a $35/sq ft erected shell. These price the whole footprint as finished living space — if part of yours is an unconditioned shop, that portion costs far less.
| Size | Sq ft | Builder-grade | Mid-range | High-end |
|---|---|---|---|---|
| 30 x 40 | 1,200 | $157,092 | $202,176 | $269,328 |
| 30 x 50 | 1,500 | $196,365 | $252,720 | $336,660 |
| 40 x 50 | 2,000 | $261,820 | $336,960 | $448,880 |
| 40 x 60 | 2,400 | $314,184 | $404,352 | $538,656 |
| 40 x 80 | 3,200 | $418,912 | $539,136 | $718,208 |
| 50 x 80 | 4,000 | $523,640 | $673,920 | $897,760 |
National averages, finished living area, land excluded. A 40 x 60 at mid-range works out to about $168/sq ft.
Barndominium cost by state
A 2,000 sq ft barndominium with mid-range finishes and a $35/sq ft erected shell, in all 51 states, cheapest first. The spread is driven by local trade wages, which is why the finish-out — not the shell — decides what you pay: the same building costs $258,951 more in Hawaii than in Mississippi.

Have barndominium costs risen in 2026?
Yes, on both sides of the build. BLS net inputs to residential construction are up 6.7% on goods and 6.2% on services over the past year, with construction materials as a whole up 10.5%. Steel and post-frame packages track the goods index closely, so a kit quote from last year is not a 2026 price.
The practical consequence: refresh the shell quote before you budget, and expect the interior trades — which are most of the cost — to have moved with local wages rather than with steel.

What this estimate does not include
- →Land. Excluded, as everywhere on this site. Barndominiums usually go on acreage, where a well and septic system add materially to the cost.
- →Utility runs. Rural sites often need power brought in, a well drilled and a septic field engineered. This can be tens of thousands before any building starts.
- →Unconditioned shop space. The calculator prices finished living area. A shop bay costs far less per square foot — price it as shell plus slab, not as house.
- →Insulating a large span. High ceilings and long clear spans mean more envelope per square foot of floor. Budget above the standard insulation allowance, especially in cold climates.
- →Financing and appraisal. Post-frame homes can be harder to finance than stick-built ones: an appraiser needs comparable sales nearby, and in many markets there are few. Lenders differ on this, so ask before you buy the land rather than after.
- →Zoning risk. Some jurisdictions restrict residential use of post-frame structures, or require an engineered design. Confirm before you buy the lot.
How this is calculated, and what we can't source
The finish-out figure comes from the same per-state cost model behind every estimate on this site, with the framing and exterior shares removed using our published line-item breakdown. That part is grounded in BLS wage data, Census benchmarks and permit-derived calibration.
The shell figure is not. There is no public dataset of barndominium kit prices — nothing from Census or BLS covers them — so the presets are broad market ranges, not measurements, and they are the least reliable number on this page. If you have a supplier quote, enter it; the estimate is only as good as that input. We would rather ask than publish an invented national average, which is the same standard we apply to cost per square foot by house size.

Barndominium cost questions
How much does a barndominium cost to build in 2026?+
A 2,000 sq ft barndominium with mid-range interior finishes costs roughly $336,960, or $168 per square foot of finished living area, assuming a $35/sq ft shell package erected by a crew. That is about 10.4% less than the $376,000 a comparable stick-built home would cost. The saving comes from the shell only — the shell replaces about 29% of a conventional build, and the remaining trades cost the same either way.
Are barndominiums actually cheaper than a regular house?+
Somewhat, and less than most people expect. A post-frame or steel shell replaces framing and the exterior envelope, which is about 29% of a conventional build's cost. Foundation, plumbing, electrical, HVAC, insulation, cabinets, flooring and fixtures are unchanged. If you specify a high-end interior, the shell saving is a small fraction of the total and the two converge.
What does a barndominium shell kit cost per square foot?+
Broadly: about $20/sq ft for a materials-only kit you erect yourself, $35/sq ft for a kit with professional erection, and $50/sq ft for a turnkey weathertight shell. Kit pricing varies by span, eave height, and local snow and wind loads, and there is no public dataset of barndominium kit prices — get a supplier quote and enter it rather than relying on a national average.
Can you get a mortgage on a barndominium?+
Often, but with more friction than a conventional home. Lenders treat a barndominium as non-standard construction, appraisers may struggle to find comparable sales, and a structure with a large unconditioned shop attached can fall outside conforming loan guidelines. Talk to a local lender before buying land, not after.
