A barndominium is a post-frame or metal-skinned home that may have a shop; a shouse — shop-house — is a shop that has a home. Structurally they are the same building. The difference is proportion and purpose, and that difference follows you to the county, the assessor, the lender and the insurer. The terms get used interchangeably by manufacturers and buyers; the people who evaluate the finished building do not use them at all. They look at living area, shop area, and use.
Barndominium, shouse and post-frame home: definitions
- Barndominium (barndo): a home built with post-frame or steel-building construction and a metal skin. Living area is the point; a garage or shop is common.
- Shouse / shop-house / shop home: a building where a large shop — typically 1,200 to 3,000+ square feet with tall doors — is the point, with living quarters attached or above.
- Pole-barn home / post-frame home: the same thing described by structure rather than purpose.
- Metal building home: usually a pre-engineered steel structure.
When a shouse makes sense
A manufacturer's rule of thumb is that the shouse wins once the shop exceeds about 1,200 square feet — below that, an attached garage on a conventional house or a separate pole barn is cheaper. The shouse buyer in the St. Louis ring is a contractor or mechanic working from home, an acreage owner with equipment, a boat-and-RV household near the region's lakes, or anyone whose hobby needs a lift. The shouse's economics: shop space at $55–$80 per square foot finished sits under the same roof as living space at $160–$230, so a 1,800/1,600 split costs far less than a 3,400-square-foot house.
Financing, zoning and resale challenges for a shouse
- Appraisal. Lenders following Fannie Mae's guidance want the living space to be the dominant use with comparable sales that support it; an 1,100-square-foot apartment on a 3,000-square-foot shop reads as a shop with a residence and may not find comps at all. See financing and appraisal.
- Zoning. Inside cities and covenants, garage and accessory-area caps bite a shouse first. On rural county land, the minimum-lot rules apply to the dwelling and the shop comes along.
- Insurance. A big shop invites the underwriter's questions about welding, fuel, business use. See insurance.
- Tax. A residential shop is assessed at 19% like the house; it is agricultural at 12% only if actually used for farming on ag land. See property tax.
- Resale. A shouse sells to a shouse buyer. In a growth county like Lincoln or Warren that pool is real; in a St. Charles County subdivision it is small.
Layouts
| Layout | Pros | Cons |
|---|---|---|
| Side-by-side (living on one end, shop on the other) | Simplest, cheapest, easiest to appraise; one roofline | Long building; shop noise next to living |
| Living over the shop | Small footprint; views | Fire separation, stairs, HVAC, cost per square foot up; harder appraisal |
| L or T | Porch and yard side away from shop doors; better on slopes | Roof valleys, cost |
| Breezeway-connected shop | Dodges attached-garage caps in covenants | Loses single-roof economy; two slabs |
What we recommend, in general
For most buyers: a barndominium with living space clearly dominant — 1,800 to 2,600 square feet of home with a 900 to 1,600-square-foot shop — side by side, one roof, a fire-rated wall between, conventional windows and finish on the living side. It builds cheapest, appraises best, insures easiest and sells widest. For the buyer whose work needs a 3,000-square-foot shop, build the shouse — but plan the financing and the covenant check around the shop before the plans are drawn.
Frequently asked questions
Is a shouse cheaper than a barndominium? Per total square foot, yes, because shop space is cheap. Per square foot of living area, no.
Can I finance a shouse? Yes, with the living-space-dominant and comps cautions above. Farm Credit will on ten acres; USDA only if the dwelling is clearly the purpose.
Can the shop be a business? Rural county land usually allows it; cities and covenants limit home occupations; tell the insurer.
