What Shops, Garages and Barndominiums Cost in Southwest Missouri
These are market ranges from published cost data, not our quote. What your build costs depends on size, eave height, doors, concrete and finish.
Where the money actually goes
FBi Buildings publishes the split for a standard 40×60. It holds up well as a way to read a quote: if two bids are far apart, the gap is almost always in concrete, site prep or finish level, not in the steel.
- Shell
- 40%
- Finishing
- 25%
- Concrete
- 20%
- Site prep
- 14%
- Permit
- 1%
Why published figures disagree by roughly 2×
You will find post-frame cost quoted anywhere from $15 to $60 a square foot, and the spread is not sloppiness. HomeGuide and Angi put installed cost at $15–$40 per square foot. Those ranges absorb DIY kits and minimal-spec agricultural buildings with no slab and no finish. FBi Buildings, a full-service post-frame builder, publishes $35–$50 per square foot for a 40×60 shell.
Averaging those two numbers would produce a figure that describes nothing real. They are measuring different products. Read the low end as "a kit and a bare pad," and the high end as "a finished building someone else builds and stands behind," then decide which one you are actually shopping for before you compare bids.

Ranges are market data, not our quote. What yours costs depends on site, height, doors and finish.
Detached garages by size
| Item | Range | Source |
|---|---|---|
| Detached garage | $50–$100 per sq ft | HomeGuide |
| 20×20 two-car | $20,000–$40,000 | HomeGuide |
| 24×24 | $28,800–$57,600 | HomeGuide |
| 36×24 three-car | $43,200–$86,400 | HomeGuide |
RV and oversized buildings
HomeGuide puts an RV garage at $50,000 to $160,000. The spread is real and it tracks height and depth: a coach needs 12 to 14 ft of clear door height and 40 to 50 ft of depth, and both push the structure. Tall overhead doors sit at the top of the $700–$2,700 each range, and taller eaves push post embedment toward the deep end of Greene County's 28–64 inch table.
Barndominiums and living quarters
| Item | Range | Source |
|---|---|---|
| Pole barn with living quarters | $30,000–$120,000 | HomeGuide |
| Complete pole barn house, 2,400 sq ft finished | $120,000–$300,000 | HomeGuide |
| Barndominium, 2,000 sq ft finished steel-frame | $150,000–$315,000 | HomeGuide |
| Finishing over the shell | $35–$110 per sq ft | HomeGuide |
| Total project | $150–$400 per sq ft | FBi Buildings |
Both counties cap living quarters at 1,000 sq ft. See the permit guide for what that cap requires structurally.
Concrete and slab
| Item | Range | Source |
|---|---|---|
| Concrete slab installed | $6–$12 per sq ft | HomeGuide |
| Materials alone | $3–$7 per sq ft | HomeGuide |
| 4-inch slab | $6–$8 per sq ft | HomeGuide |
| 6-inch slab | $8–$10 per sq ft | HomeGuide |
| Two-car garage floor | $2,400–$6,900 | HomeGuide |
| Labor share of slab cost | 40–50% | HomeGuide |
The 4-inch versus 6-inch decision is not cosmetic — it is about what drives onto it. Slab spec and site prep →
Site prep and grading
| Item | Range | Source |
|---|---|---|
| Land leveling | $0.40–$2.00 per sq ft | HomeGuide |
| Site prep, residential | $500–$5,000 | FBi Buildings |
| Site prep, agricultural | $1,000–$30,000 | FBi Buildings |
| Site prep | $1,200–$8,000 | Angi |
This is the line item that most often separates two bids that looked identical. A flat, dry, accessible site sits at the bottom of these ranges. A sloped site with fill, a culvert and a long approach does not.
Doors, windows, insulation and electrical
| Item | Range | Source |
|---|---|---|
| Overhead doors | $700–$2,700 each | HomeGuide |
| Walk doors | $300–$1,900 | HomeGuide |
| Windows | $150–$1,000 each | HomeGuide |
| Spray foam | $1.00–$4.50 per sq ft | HomeGuide |
| Electrical | $6,000–$22,500 | HomeGuide |
| Roofing | $3–$6 per sq ft | HomeGuide |
| Siding | $3–$13 per sq ft | HomeGuide |
Barndominium versus conventional, per square foot
HomeGuide puts a traditional home at $180–$280 per square foot and finished metal at $50–$145 per square foot. The savings are real, but they sit in the shell. Kitchens, baths, HVAC, flooring and trim cost the same whether the walls around them are posts or studs, which is why finishing runs $35–$110 per square foot either way.
Missouri-specific figures
FBi Buildings publishes Missouri permit costs at $200–$600 and Missouri shell cost at $35–$60 per square foot, and names four regional cost factors: wind load, snow load, soil bearing and delivery distance.
Note that the local offices around Springfield largely do not publish their own fee schedules — FBi's figure is a statewide market observation, not a Greene County or Christian County quote. Who to call for your actual fee →
What pushes a job to the high end
- Eave height. It drives embedment, column length, siding area and door price all at once.
- Door count and door size. Tall overhead doors carry framing and header cost with them.
- Slab thickness and reinforcement, especially where equipment or a lift is going.
- Site work: slope, fill, drainage and access for a concrete truck.
- Finish level — insulation, interior liner, HVAC, plumbing and electrical load.
- Engineering, where span, width or a metal structure triggers stamped plans.
- Delivery distance, which FBi names as a regional factor in Missouri.
Financing and the appraisal-comparables problem
Per Fairway Independent Mortgage, traditional lenders can be difficult to find for these buildings, and the core obstacle is appraisal comparables: if the appraiser has nothing to compare your home to, they cannot assign a value. That is a paperwork problem, not a construction problem, and it does not solve itself late in the process.
USDA loans are the most viable rural path, and much of the Greene and Christian County fringe is USDA-eligible. Talk to a lender who has actually closed one of these before you commit to a build schedule. We do not arrange financing.
