Barndominium Cost Calculator
Estimate what it costs to build a barndominium based on its size and how finished you want it, from a bare shell to a full custom interior.
What your result means
The estimated build cost is a low-to-high range based on your square footage and finish level, using typical turnkey rates per square foot. The midpoint is a reasonable planning number. This is the structure and interior — land, site prep, foundation extras, well, septic, and utility hookups are separate and can add a lot.
How to use this calculator
- Enter the total floor area in square feet (living space plus any finished shop).
- Pick a finish level: shell only, basic livable finish, or full custom.
- Read the build-cost range and use the midpoint to budget.
- Add land, site prep, foundation, and utilities on top.
- Get local builder quotes — regional labor and material costs vary widely.
The formula
Barndominium cost scales mostly with size and how finished the interior is. A bare metal shell is cheap per square foot; a fully finished custom home approaches conventional construction costs.
Worked example
A 2,400 sq ft barndominium at a basic livable finish uses a $115 per sq ft rate, so the base is about $276,000. The range lands near $248,000 to $317,000, with a midpoint around $283,000. A shell-only version of the same size would be closer to $108,000, before land and utilities.
Barndominium cost by finish level
| Finish level | Typical $/sq ft | What's included |
|---|---|---|
| Shell only | $30 - $60 | Frame, metal skin, slab — you finish inside |
| Basic finish | $100 - $130 | Insulation, drywall, basic kitchen & baths |
| Full custom | $160 - $200+ | High-end finishes, custom layout |
| Land & site prep | Varies | Clearing, grading, driveway — extra |
| Well / septic / utilities | $15k - $40k+ | Rural hookups — extra |
Tips & gotchas
- Shell-only looks cheap, but finishing it yourself still costs real money and time.
- Site prep can blow a budget — grading, fill, and a long driveway add up fast.
- Rural builds often need a well and septic; budget $15k-$40k before you start.
- Steel prices swing; lock in your kit or quote when you commit.
- This is the build only. Land, permits, and utilities are separate line items.
Frequently asked questions
How much does a barndominium cost to build?
A finished barndominium typically runs $100 to $200 per square foot, so a 2,400 sq ft home lands around $240,000 to $480,000 — before land and utilities. A bare shell is far less.
Is a barndominium cheaper than a regular house?
The shell is cheaper and goes up fast, but a fully finished barndominium costs about the same per square foot as conventional construction once you add a real interior.
What's not included in the build cost?
Land, site prep, foundation extras, well, septic, utility hookups, permits, and appliances. These can add tens of thousands.
Does size change the price per square foot?
Somewhat. Larger buildings spread fixed costs over more area, so the per-square-foot rate often dips a little as size grows.
Can I finance a barndominium?
Yes, though some lenders treat them differently than traditional homes. Construction and post-frame loans are common; check with local lenders.
