What costs are on top of the building?
- Site work: $20,000 to $50,000 for clearing, grading, the concrete slab and access.
- Spray foam insulation: $15,000 to $30,000. Metal buildings need a good vapor barrier to prevent condensation, which is why spray foam is common.
- Contingency: set aside 10% to 15% for overruns.
- Land, well, septic and utility connections: priced separately; see the cost breakdown.
- Shop or garage space: many barndos include a workshop bay. Unfinished shop space costs much less per sq ft than living space, so price the two separately.
Why is a barndominium cheaper than a regular house?
Houseplans.com estimates barndominiums cost 15% to 25% less than a comparable stick-built home. The savings come from a pre-engineered steel frame that goes up quickly, a simple rectangular footprint with one large roof, and open floor plans with fewer interior walls. The savings shrink once you add premium finishes, a complex roof line or lots of windows. Compare the two in detail in barndominium vs house.
Can you finance a barndominium?
Yes, usually with a construction loan that converts to a mortgage once the home is finished. Some lenders and appraisers have fewer comparable sales for barndominiums, so expect more questions at appraisal and shop around for a lender who has financed them before.
