Tulsa Barndominium
Shell Cost Estimator
Size the shell, see a planning budget and separate the work needed to turn it into a finished project.
Get a shell budget in under a minute
Start with the enclosed footprint. Then add amounts you know for work outside the shell. No email or phone number is required.
1. Size the shell
Count the intended living and shop footprint once. Leave upper floors, lofts and covered porches out. Example sizes do not establish a completed design.
2. Add your project assumptions
Use your own quotes or planning allowance for unpriced work. Zero means unresolved, not free. The default 10% reserve is a scenario, not a professional recommendation.
PARTIAL SHELL BUDGET
$158,000–$291,000
Includes your entered extra-work allowance and reserve. Interior completion and site-specific work remain unpriced.
Regional insulated-shell-with-slab benchmark. This is not a verified Tulsa price range, a partner quote or a move-in-ready home price.

The reference includes a slab. Do not count the same slab again. Engineering, exact door/window scope, insulation performance and site conditions need a written proposal.
Nothing is submitted. Your choices stay in this tab.
3. Plan the work beyond the shell
Confirm land preparation, foundations, utility and septic connections, permits, porches and every interior trade. Our installation partner’s actual shell and concrete scope is agreed separately; this calculator does not promise turnkey interior completion.

Pricing evidence and calculation
Model tulsa-shell-2026-10-03, checked October 3, 2026. Revolve’s barndominium scope guide publishes $60–$110/sq ft for an insulated shell with slab in the St. Louis region. We use this as a regional comparison because a verified Tulsa shell price book is not available. It is not our installation partner’s approved rate.
Calculation: enclosed ground-floor footprint × $60–$110, plus your entered allowance, then your reserve percentage. Results round outward to $1,000. No Tulsa multiplier, financing assumption, land value, porch price or interior-finish allowance is guessed. More answers do not automatically narrow the range.
Land, excavation/grading, unusual foundations, utilities/septic, permits/design, porches, interior framing and finishes, plumbing/electrical/HVAC, appliances and taxes/fees beyond a written scope require separate pricing. Research benchmarks can change; review the source before relying on a saved estimate.
