Barndominium Kits: Every Serious Supplier, Priced and Compared
Updated July 2026 · Barndo Finder research

A barndominium kit is the structural package for the building: frame, sheeting, fasteners, and engineered drawings, delivered on a truck. Real steel kits run about $20 to $35 per square foot for materials in 2026, and wood post-frame packages run higher because they include more parts. The kit is usually 15 to 25 percent of your finished cost, so a $30,000 kit does not mean a $60,000 house.
Key takeaways
- Steel barndominium kits cost roughly $20 to $35 per square foot for materials. That covers frame, panels, and fasteners, nothing else.
- Finished barndominiums land at $125 to $320 per square foot turnkey by state, per our cost data. The kit is a minority of that number.
- General Steel and Worldwide Steel Buildings publish usable price guidance. DC Structures publishes model prices. Most other suppliers make you call.
- Small kits cost more per square foot, not less. Freight and engineering do not shrink with the building.
- Any "turnkey" quote under $100 per square foot is almost certainly a shell quote wearing a costume. Ask what is excluded, in writing.
What does a barndominium kit actually include?
A steel kit includes the primary framing, secondary framing, wall and roof sheeting, and the fasteners to bolt it together, plus stamped engineering drawings. That is the standard package General Steel describes, and it matches what most steel suppliers ship. Doors, windows, insulation, and wainscot are add-ons you price separately.

Wood kits carry more. DC Structures' post-frame packages include pre-cut lumber, siding, windows, doors, and hardware. Barndominiums.com sells plans alone, plans plus a wood kit, or plans plus a steel kit with pre-assembled wall panels and trusses.
No kit on the market includes the concrete slab, plumbing, electrical, HVAC, septic, well, or a single sheet of drywall. That is where most of your money goes. If a salesman blurs that line, walk. Our shell versus turnkey breakdown shows exactly where each route leaves you.
How much do barndominium kits cost in 2026?
Materials run $20 to $35 per square foot for steel and more for full wood packages, and the numbers below are published by the suppliers themselves. We keep a supplier-by-supplier breakdown in our kit price comparison. Here is what that looks like on real building sizes, using General Steel's published ranges plus their line items for the work a kit does not cover.
| Size | Sq ft | Kit (building system) | Concrete slab | Erection labor | Interior finish |
|---|---|---|---|---|---|
| 30x40 | 1,200 | $24,000 to $37,200 | $12,000 to $18,000 | $8,400 to $14,400 | $48,000 to $192,000 |
| 40x60 | 2,400 | $60,000 to $93,000 | $30,000 to $45,000 | $21,000 to $36,000 | $120,000 to $480,000 |
| 60x70 | 4,200 | $72,000 to $111,600 | $36,000 to $54,000 | $25,200 to $43,200 | $144,000 to $576,000 |

Look at that table honestly. On the 40x60, the kit is $60,000 to $93,000 and the finished project is plausibly $231,000 to $654,000 before land. The kit headline is the smallest number on the page. Budget from the right side of the table, not the left.
Steel frame or post-frame wood: which kit should you buy?
Steel wins on spans, warranties, and pests; wood wins on finishing cost and available labor. A steel frame kit gives you clear spans with no interior load-bearing walls, and suppliers back the structure hard: Worldwide Steel Buildings offers a 50-year structural warranty on frame members. Steel does not rot and termites ignore it. If you go steel, our red iron kit guide compares suppliers and steel grades.

Post-frame wood is easier to insulate, easier to hang drywall and cabinets in, and every rural county has crews who have framed pole buildings for decades. Attaching interior walls to red iron requires furring and know-how that some finish carpenters do not have. That labor gap is real and it shows up on your invoice.
Our position: if you are building a shop-heavy barndo with big open bays, go steel. If you are building what is mostly a house with a garage attached, post-frame wood usually finishes cheaper and faster. Get both priced through our quote form before you commit.
Worldwide Steel Buildings: the steel kit benchmark
Worldwide Steel Buildings sells bolt-together steel shell kits with a web truss system, made in Missouri, and it is the supplier we measure others against. Published guidance puts kits at roughly $10 to $30 per square foot depending on options like porches and second-floor mezzanines, with a 50-year structural warranty on primary and secondary members. Our full Worldwide Steel Buildings review digs into the engineering and pricing.
Public sentiment is mostly positive. A Missouri owner on Reddit reported a smooth purchase and liked that the web truss design stays visible inside the finished house, though county permitting slowed his project. Review sites note customer service can feel corporate and steel tariffs have been pushing prices up.
Who it fits: DIY-leaning owners who want an engineered steel shell with a long warranty and are handling the rest themselves. Who should look elsewhere: anyone who wants one contract covering shell through move-in. Worldwide sells you a building, not a house.
General Steel: transparent pricing, mixed service record
General Steel is one of the few national suppliers that publishes real numbers, and that transparency is worth something. Kits are $20 to $31 per square foot for materials, with the size-by-size breakdowns in the table above.
The record is genuinely mixed. Reviews consistently praise staff communication and process guidance. But BBB complaints tell a rougher story: one customer reported losing a $14,000 deposit and receiving only unusable plans for a 30x40, and a 2024 complaint describes a nonprofit paying over $28,000, then learning after payment that container loading was not offered and storage would run $2,000 per week. ComplaintsBoard aggregates a middling rating on a small sample. We cover the complaint record in detail in our General Steel review.
Who it fits: buyers who want published pricing and a big-company process, and who read contracts line by line. Who should look elsewhere: anyone uncomfortable with large deposits paid before drawings are in hand. With any national broker-style supplier, get every exclusion, storage term, and refund condition in writing before money moves.
DC Structures: premium wood kits, premium prices
DC Structures sells high-spec post-frame wood kits, not steel, and does not pretend to be cheap. Published model prices run from about $93,000 to $364,000 depending on the design, and the Meridian model starts around $90,000 to $150,000 for the base package. Kits include engineered plans, pre-cut lumber, Western red cedar siding, Andersen windows, doors, and hardware, backed by a 10-year limited materials warranty. Our DC Structures review goes model by model.
Reviews are thinner than for the steel giants; there is no BBB listing, and most testimonials live on DC's own site. The recurring complaint in independent reviews is sticker shock: the kit excludes construction, and DC's own guidance is that turnkey cost typically lands 3 to 5 times the kit price. A $150,000 kit implying a $450,000 to $750,000 project is consistent with our state cost data for a large, well-finished build.
Who it fits: buyers who want a wood barndominium that looks like an architecture magazine and have the budget to match. Who should look elsewhere: anyone shopping on price per square foot.
Barndominiums.com and the budget metal kit tier
Barndominiums.com sells plans plus wood or steel kits, with published pricing from $22 per square foot for their Quick Start kit up to $40 to $45 per square foot for the Ultimate package, and claims up to 65 percent of framing arrives pre-assembled. Custom plans turn around in as little as 7 days. Final pricing depends on your snow and wind loads, so treat the low number as a floor.
Below that sits the carport-industry tier: Carport Central, Eversafe, Titan Steel, and similar sellers advertising very cheap metal barndominium kits. These are light-gauge tube-steel structures. Some are fine as shops. As houses, they need careful engineering review for residential loads, insulation, and financing, and lenders are pickier about them.
Regional manufacturers are the other option worth pricing. Mueller, Inc. rolls its own steel at 36-plus locations across Texas, Oklahoma, Arkansas, and neighboring states, with panels thicker than industry standard. Mueller sells engineered buildings and shells rather than residential kits per se, but plenty of Texas and Oklahoma barndos start life as a Mueller building with a local crew doing the finish. See our Mueller buildings review for how their shells work as homes.
What will the kit never cover?
Land, dirt work, utilities, and finish, which together dwarf the kit. A real budget has lines for land, clearing and pad, driveway, well or water tap, septic or sewer tap, the slab with plumbing rough-in, kit freight, erection, and then the whole interior. Skip any of those lines and the money still gets spent, just as a surprise. The same goes for borrowing: our financing overview covers how lenders treat kit builds.
This is why kit marketing overpromises by design. The $35,000 headline is true and useless at the same time. Finished barndominiums in our directory data run $125 to $320 per square foot turnkey depending on state: Texas at $140 to $210, Tennessee at $140 to $210, Ohio at $135 to $200. These are Barndo Finder directory estimates pending verified quotes, and they include everything the kit does not.
Our take
Buy the kit last, not first. Price your land, site work, and finish level, check them against the cost tables, and only then pick the structural package that fits what is left. Worldwide Steel Buildings is our benchmark for steel kits on warranty and owner sentiment. General Steel has the most honest public pricing but demands careful contract reading. DC Structures builds the best wood kits and charges for it. The budget tube-steel tier is for shops, not homes, until an engineer says otherwise.
And hold our rule close: a turnkey number under $100 per square foot is a shell quote in disguise. Nobody is finishing a house for that in 2026.

Common questions
How much does a steel barndominium kit cost?
Plan on $20 to $35 per square foot for the steel package: frame, panels, and fasteners. General Steel publishes $20 to $31 per square foot for materials, and Worldwide Steel Buildings lists shell kits from roughly $10 to $30 per square foot depending on options. That number is not your house cost. Slab, erection, and interior finish usually triple it or more.
What is included in a prefabricated barndominium kit?
A typical steel kit includes primary and secondary framing, wall and roof sheeting, fasteners, and engineered drawings. Wood kits from suppliers like DC Structures add pre-cut lumber, siding, windows, and doors. No kit includes the slab, plumbing, electrical, HVAC, septic, or interior finish. Read the bill of materials before you sign anything.
Are small barndominium kits cheaper per square foot?
No, they usually cost more per square foot, not less. A 30x40 kit carries the same engineering, freight, and setup costs as a bigger building spread over fewer square feet. General Steel's published 30x40 building system runs $24,000 to $37,200, which is $20 to $31 per square foot before any concrete or labor. Small kits save total dollars, not unit cost.
Should I buy a steel frame or wood frame barndominium kit?
Buy steel if you want big clear spans, a long structural warranty, and lower insect and rot risk. Buy post-frame wood if you want easier interior finishing, simpler insulation, and more local crews who know how to build it. In most counties more framers can finish a wood building than a red iron one. Price both before deciding.
Can I assemble a barndominium kit myself?
Physically, some owners do, especially bolt-together web truss systems. Practically, most people should hire an erection crew for the shell and self-perform the finish work instead. Erection on a 40x60 steel kit runs roughly $21,000 to $36,000 per General Steel's published figures. A dropped rafter or a bad slab costs far more than that.
How long does a barndominium kit take from order to move-in?
Expect 2 to 4 months for engineering and fabrication before delivery, then 4 to 10 months of construction depending on crew and finish level. A year total is a realistic plan. Suppliers quote shell erection in weeks, but permits, weather, and interior trades set the real schedule.
