Four questions. We call you back and talk through size, height and what it takes on your site.
What fits in what
Start here, not with a square-foot budget. Park the vehicles on paper first, add the bench and the walk space around them, and the footprint picks itself.
| Size | Floor area | What it holds |
|---|---|---|
| 24×30 | 720 sq ft | Two vehicles plus a bench. Tight but workable. |
| 30×40 | 1,200 sq ft | Two vehicles, a bench, and room to walk around both. |
| 40×60 | 2,400 sq ft | The most-requested size here. Vehicles, shop space and storage. |
| 40×80 / 60×80 | 3,200–4,800 sq ft | Equipment, a business, or multiple bays. |
Buying an extra 10 feet of width while the crew is already on site is cheap. Adding it two years later is not.
Eave height: 10 ft, 12 ft, or 14 ft and up
- 10 ft — standard. Fine for vehicles, a bench and shelving on the walls.
- 12 ft — a two-post lift, tall racking, or a tandem trailer parked inside.
- 14 ft and up — RVs, fifth-wheels and anything with a rooftop unit. See RV garages.
Height is not a finish upgrade. It runs down into the ground. The Greene County post-frame standard sets post embedment as a table from 28 inches to 64 inches, driven by truss span and eave height. Taller wall, deeper hole.
The county spec calls for minimum 6×6 ACQ or CCA treated posts, 10-inch diameter holes with concrete backfill or 12-inch with soil backfill, and 4 inches of crushed stone under each post, with posts on 8 or 10 ft centers. Design values behind it: 20 PSF roof live load, 20 PSF ground snow, 2,500 PSF soil bearing, Seismic Design Category B.
Inside Springfield city limits the same building is checked against the 2018 IRC adoption: 20 PSF ground snow, 115 MPH ultimate design wind, Seismic Category B, 24-inch frost depth, 9°F winter design temperature, and a moderate-to-heavy termite rating.
The cost chain: more eave height → deeper embedment → more auger time, more concrete backfill and longer columns → taller headers and wall framing above the doors → more siding and more insulation on every vertical square foot.
What a shop costs in this market
Published figures for post-frame vary by roughly 2× depending on who is publishing. HomeGuide and Angi put installed cost at $15–$40 per square foot; those ranges absorb DIY kits and minimal-spec agricultural buildings. FBi Buildings, a full-service post-frame builder, publishes $35–$50 per square foot for a 40×60 shell and $35–$60 per square foot in Missouri specifically. Both are accurate about different things.
By size (HomeGuide)
- 30×40 (1,200 sq ft) — $18,000–$48,000
- 40×60 (2,400 sq ft) — $36,000–$96,000
- 40×80 (3,200 sq ft) — $48,000–$128,000
- 60×80 (4,800 sq ft) — $72,000–$192,000
Angi runs lower: 30×40 $18,000–$32,000, 40×60 $30,000–$55,000. FBi's Missouri 40×60 shell: $84,000–$120,000.
Detached garages (HomeGuide)
- $50–$100 per square foot
- 20×20 two-car — $20,000–$40,000

Ranges are market data, not our quote. What yours costs depends on site, height, doors and finish.
Before you set the size
The pad is its own decision — slab thickness, thickened edges and pad elevation all get settled before framing. See concrete and site prep. If a coach or fifth-wheel is going inside, jump straight to RV garages — the height math is different. Paperwork depends on where you sit: check the permit rules by jurisdiction.

Shop and garage questions
- What size shop do most people in Springfield end up building?
- 40x60 is the most-requested size in this market. It holds vehicles, a work area and storage without crowding. 30x40 is the common step down for two vehicles and a bench, and 40x80 or 60x80 is where equipment, multiple bays or a home business go.
- Is a 12-foot eave worth the extra money over 10 feet?
- If you plan to add a lift or stack storage, yes. A lift needs headroom you cannot add later without rebuilding walls. Going taller also pushes post embedment deeper on the Greene County table, so the cost shows up in auger time, concrete and column length as well as siding.
- Why do post-frame prices online range from $15 to $60 a square foot?
- The low end absorbs DIY kits and bare agricultural buildings. The high end is a full-service builder delivering a finished shell on a prepared site. Both numbers are accurate about different products. Ask any builder what is inside their number before comparing.
