Barndominiums have gone from a rural novelty to one of the most-requested builds we do around Perry County and the surrounding counties. They’re flexible, they go up fast, and done right, they’re beautiful.
They’re also widely underestimated on budget — usually because people price the steel shell and forget that the inside of a barndominium costs about the same as the inside of any other house.
Here’s the honest breakdown.
Shell vs. turnkey: two very different numbers
The single biggest source of confusion is what “barndominium cost” even means.
- Shell (dried-in): the structure, roof, exterior, windows, and doors — weather-tight but unfinished inside. Roughly $55–90 per square foot in our area.
- Turnkey (finished): everything above plus insulation, interior framing, electrical, plumbing, HVAC, kitchen, baths, flooring, and trim — move-in ready. Roughly $140–220 per square foot.
When someone quotes you a barndominium at “$70 a foot,” they’re almost always talking about a shell. That’s not dishonest — it’s just a different scope. Know which number you’re looking at.
What actually drives the budget
Square footage matters, but these line items move the number more than people expect:
- Site work. Clearing, grading, a building pad, and a driveway. Sloped or wooded land costs more to prep.
- Well & septic. If you’re not on utilities, budget for both. This is the most-forgotten cost on raw land.
- The kitchen and baths. Cabinets, counters, fixtures, tile — this is where finished-home costs live, barndominium or not.
- HVAC. A big open shell needs the right system sized correctly. We often use mini-splits for efficiency in these layouts.
- Ceiling height & open spans. That dramatic open great room is gorgeous — and the wide spans and tall walls add structural and finishing cost.
- Finish level. Builder-grade vs. custom changes everything. The shell is the shell; the finishes are where you spend or save.
Where people underestimate
In our experience, first-time barndominium owners most often under-budget:
- Site prep and the driveway
- Well and septic on raw land
- Insulation and HVAC for a large open volume
- The kitchen — they price the shell carefully and the kitchen casually
Build those in from the start and you avoid the worst part of any project: running out of money at the finish line.
A realistic way to phase it
One advantage of a barndominium is that it phases well. A common approach we use:
- Site work + shell — get it dried in and weather-tight.
- Rough-ins — electrical, plumbing, HVAC, insulation.
- Finish-out — kitchen, baths, flooring, trim, paint.
Some homeowners finish it all at once; others dry it in, then finish the interior as budget allows. Either path works if it’s planned from the beginning instead of improvised.
Financing reality
Barndominium financing has gotten easier but still isn’t identical to a standard mortgage. Some lenders treat them differently, and a turnkey, code-built barndominium appraises far better than a bare shell. We’re happy to build to whatever a lender needs to see.
If you’ve got land — or you’re shopping for it — and a barndominium on your mind, the best first step is a walk of the site and an honest, itemized budget that includes the parts people forget. That’s the conversation that keeps a build on track. We’re glad to have it.
