How much does a 40x50 barndominium cost?
A right-sized favorite — 2,000 sq ft under roof, and an honest range for it.
Published August 1, 2026
The 40x50 is the size a lot of people land on once the wish list meets the budget — big enough for a real family home with a garage or shop under the same roof, without stepping up to the footprint of the biggest builds. Like most barndominiums, it gets searched by its dimensions, not its square footage, so let us close that gap first: a 40-foot by 50-foot building is 2,000 square feet on one level. That is the number the budget runs on.
As a planning range, a turnkey 2,000 sq ft barndominium runs about $304,000 to $368,000 in lower-cost states like Texas, Tennessee, and Georgia, and up to roughly $665,000 to $805,000 in the highest-cost states. That is a wide spread, and the state you build in moves it more than almost anything else. Here is what sits inside that number, and what sits outside it.
The 40x50 number — and what it leaves out
A 40x50 barndominium is 2,000 sq ft under roof. In the lower-cost states we serve, a turnkey build runs about $304,000 to $368,000. In the highest-cost states, the same 2,000 sq ft can run $665,000 to $805,000. Most states land somewhere in between.
That range covers the home build from sub-slab plumbing and up — living space, garage or shop, and covered porches, all combined under the roof. It does not cover the land or what it takes to make that land buildable. Those costs are real, they vary wildly by site, and we put them on the table early rather than letting them surprise you at the end.
This is a planning range for total under-roof square footage — living space, garage, and covered patios/porches combined — based on current scope and assumptions and subject to review. It covers the home build from sub-slab plumbing and up. It does not include land, site work, utilities, septic or well, driveways, or finish upgrades. A precise number requires plans and lender pre-approval — until then, any figure is an estimate, not a quote or guarantee.
The levers
Four things that move a 40x50 the most.
01
The state you build in
Our under-roof rate ranges from about $152/sq ft in the lower-cost states to over $400/sq ft in the priciest. On 2,000 sq ft, that difference alone is hundreds of thousands of dollars — before a single upgrade.
02
Living vs. shop split
A 40x50 that is mostly finished living space costs more than one that gives up a bay or two to an insulated shop. The rate is blended across everything under the roof, but how much of that footprint you finish out is a real lever.
03
Ceiling height and a loft
Tall ceilings, exposed steel, and a loft over part of the 40x50 all add square footage or complexity. A loft is finished space too — it adds to the number the same way the ground floor does.
04
Finish level
Builder-grade and high-end land in very different places. Cabinets, flooring, windows, and fixtures are where two identical 40x50 shells drift thousands of dollars apart.
Outside the build number
What the 40x50 range does not include.
The build number is only part of what you will spend. These live outside it, and they are the difference between a plan that holds and a budget that blows up:
- 01Land and the site work to make it buildable
- 02Utilities, septic or well, and long service runs
- 03Driveway, clearing, and grading
- 04Finish upgrades beyond the planning assumptions
How Solvara fits in.
We design your 40x50 around how you actually want to use it, ground the budget against the real drawings and the real site, and get you build-ready — then make qualified introductions to construction professionals when you are ready. We are not the builder or general contractor, and the contract to build is between you and the builder you choose. The point is simple: know what your 40x50 costs, and what it leaves out, before you commit.
Common questions
Straight answers, up front.
- How much does a 40x50 barndominium cost?
- A 40x50 barndominium is 2,000 sq ft under roof. As a planning range it runs about $304,000 to $368,000 turnkey in lower-cost states like Texas, Tennessee, and Georgia, and up to roughly $665,000 to $805,000 in the highest-cost states — from sub-slab plumbing and up. That excludes land, site work, utilities, septic or well, driveways, and finish upgrades. A precise number requires finished plans and lender pre-approval.
- How many square feet is a 40x50 barndominium?
- A 40x50 footprint is 2,000 square feet on a single level. Adding a loft or second story increases the finished square footage — and the cost — above that.
- Is a 40x50 barndominium big enough for a house and a garage?
- For many people, yes. A common 40x50 layout puts a three-bed home on one end and an attached garage or insulated shop on the other, all under one roof. How you split living versus shop space is one of the biggest levers on both cost and how the home lives.
- How does a 40x50 compare to a 40x60 barndominium?
- A 40x50 is 2,000 sq ft; a 40x60 is 2,400 sq ft — the same width, ten feet deeper. The extra 400 sq ft usually goes toward a larger shop or an added bedroom, and it moves the budget by roughly the under-roof rate times 400. Which size fits depends on how much shop or living space you actually need, not on the round number.
- Does Solvara build 40x50 barndominiums?
- No. Solvara is a preconstruction planning and coordination company, not a builder or general contractor. We design your 40x50, ground the budget against the real plans and site, and get you build-ready — then make qualified introductions to construction professionals who build in your state.
