40×60 · custom-designed
40×60 Barndominium
A 2,400 sqft (40 ft × 60 ft) custom steel barndominium — the classic shop-house footprint. Shell kits from $28/sqft, turnkey via our vetted contractor network where coverage exists. We design custom plans built around your household and site, not stock floor plans.
Pricing
How Much Does a 40×60 Barndominium Kit Cost?
The shell kit for a 40×60 starts from $67,200 — that’s $28/sqft across the full 2,400 sqft footprint. Turnkey (the finished, move-in-ready build coordinated through our vetted contractor network) starts from $276,000, at a blended national rate of $115–$200/sqft, all-in across the full footprint.
Finish level on the living side is the biggest single variable in the turnkey range. Cabinets, flooring, countertops, and fixtures can roughly double the per-sqft cost between a builder-grade package and a high-end finish — meaning two 40×60 homes with identical shells can land at very different total numbers based entirely on interior choices. Shop sidewall height and overhead-door spec are the next biggest drivers on the structure side: stepping from a 14 ft sidewall to an 18 ft sidewall is a real cost increase, and speccing two 12×14 overhead doors instead of one adds both structural and hardware cost.
Whether the shop is conditioned — insulated and HVAC’d for a heated workshop — or left as open shop space is another meaningful swing, since conditioning a 1,000+ sqft shop space adds insulation, spray foam, and mechanical runs. A loft add-on over the living side, foundation type (standard slab vs. frost-protected vs. pier), and site-specific work — utility runs, septic, well, and driveway — round out the range. Geography is ultimately the single biggest cost driver: Midwest and Southern rural markets sit at the low end; rural Northeast, mountain West, and Pacific Northwest sit at the high end.

What fits
What Can You Fit in a 40×60 Barndominium?
In the default shop-house split, the 40×60 gives you roughly 1,200–1,400 sqft of living alongside a 2-bay shop — enough living space for 2–3 bedrooms, 2 bathrooms, an open kitchen and great room, a utility room, and an entry, with the shop side accommodating two full-size trucks or one vehicle plus serious workshop space.
That shop-to-living balance is what defines this footprint. The shop side is large enough to be genuinely functional — not a single-car garage dressed up as a shop, but a purpose-built work bay with custom sidewall height and overhead-door spec. The living side is a complete home, not a bunkroom attached to a warehouse. Both halves are full-sized, and both share a single engineered steel envelope.
If your needs shift, the footprint supports two real alternatives: an all-living configuration delivers 2,400 sqft of single-story home — typically 3–4 bedrooms, 2–3 baths, great room, kitchen/dining, utility, and a covered porch — with no shop at all. A living-plus-small-shop layout puts roughly 1,800 sqft of living (3BR/2BA, open plan) alongside a single-bay 600 sqft attached shop or garage. A custom design lets you shift the dividing wall to bias more shop or more living based on your actual use.
The 40×60 advantage
The First Footprint Where the Shop Is a Real Shop
The 40×60 is the entry point for a true 2-bay shop-house — not a garage-and-home compromise, but 2,400 sqft split between a full working shop and a complete 2–3 bedroom home in one steel envelope. The step up from a 30×50 (1,500 sqft) isn’t just more square footage — it’s the difference between a single-bay shop that fits one vehicle and a 2-bay shop that fits two full-size trucks plus a workbench, with sidewall height and overhead-door spec custom to your operation.
No smaller footprint in the barndominium range delivers both halves at full scale. Below 40×60, you’re trading shop depth or living comfort to make the numbers work. At 40×60, both sides are complete — which is why tradespeople, contractors, and serious hobbyists who have priced the alternatives keep landing here.
Layouts
How a 40×60 Can Lay Out
We design custom plans — not stock floor plans. The 2,400 sqft footprint runs from an all-living home to a shop-forward build, drawn around your household and site.
The same 40×60 shell runs the full range — from All-living to Mostly shop, and anywhere in between. These are common starting points, not fixed plans. Every 40×60 we build is custom-drawn from scratch.
Drawn to scale. The living-to-shop split shown is just one of many possible layouts — every 40×60 is designed from scratch.
The default shop-house split places roughly 1,200–1,400 sqft of living on one end and the 2-bay shop on the other, with the dividing wall positioned to suit your ratio. Your plan can shift that wall to bias more shop depth — fitting deeper equipment, a car lift, or a spray booth — or more living if a third bedroom matters more than the second bay. Sidewall height and overhead-door count are set in your custom plan, not fixed by the footprint.
The all-living configuration uses the full 2,400 sqft as a single-story home — typically 3–4 bedrooms, 2–3 baths, great room, kitchen/dining, utility, and a covered porch. This layout suits buyers who want a large, efficient single-story barndominium with no shop at all; the steel construction still delivers the span, finish, and durability without any of the shop-side allocation.
A loft over the living side is a common 40×60 add-on, picking up usable area — a fourth sleeping room, a home office, or bonus storage — without increasing the footprint. Other custom options include vaulted great-room ceilings, covered porches front or back, exterior color and metal-panel selection, and finish package on the living side. The mostly shop layout — where the shop claims the majority of the floor plan and the living quarters are compact — is also buildable on this footprint, though the 40 ft width means the shop reads deep and wide rather than providing long run depth; buyers whose primary need is maximum shop depth with minimal living should also look at the 40×80.
Best for
What a 40×60 Barndominium Is Best For
The 40×60 suits owner-builders, tradespeople, and small families who want a serious shop and a complete home in one envelope — without building two separate structures on the property.
Tradespeople and contractors are the strongest fit: the 2-bay shop accommodates work trucks, tools, and equipment inside a climate-controlled or open shop, while the attached living side eliminates a separate commute between home and work facility. For a plumber, electrician, or HVAC contractor running a small crew, the 40×60 covers both the job and the household in one build.
Hobbyists — woodworkers, gearheads, fabricators — find the 40×60 compelling because the shop can be designed from the start around their equipment: bay width, door height, electrical service, and floor spec are all set in your custom plan, not retrofitted into a residential garage. Small families wanting acreage living with the shop attached rather than as a separate building are a consistent buyer at this size, as are rural downsizers and working homesteaders who need covered storage for tractors, ATVs, and project vehicles alongside a right-sized home.
Size comparison
40×60 vs. Other Sizes
| 40×60 | 30×50 | 40×80 | |
|---|---|---|---|
| Footprint | 2,400 sqft | 1,500 sqft | 3,200 sqft |
| Turnkey range | $276,000–$480,000 | $172,500–$300,000 | $368,000–$640,000 |
| Best for | Tradespeople, shop hobbyists, small families | Home + small shop bay, starter footprint | Homestead shop-house, bigger home, extra shop depth |
The 40×60 is the entry point for a real shop-house — the 30×50 (1,500 sqft) delivers a comfortable home alongside a single-bay shop, but the step to 40×60 is a product change, not just a size increase: the second bay, the additional living depth, and the sidewall flexibility make the 40×60 a categorically different build. It’s the first footprint where you don’t have to compromise one side to fund the other.
The 40×80 (3,200 sqft) keeps the same shop-house shape and 40 ft width but adds 800 sqft — enough to expand the home to a true 3-bedroom layout with bonus space, add a third shop bay or RV depth, and accommodate homestead-scale equipment storage. If your household needs a larger home or your shop work involves longer equipment or an additional bay, the 40×80 is the natural next step without changing the structural width.
Kit or turnkey
Kit or Turnkey: How Most Buyers Build a 40×60
Most buyers at this size choose turnkey because they can’t erect a steel shell themselves. Here’s exactly where the kit ends and the finished home begins.
The shell kit includes the engineered steel frame, roof and wall panels, fasteners, hardware, and delivery to your site — the bones of the 40×60, ready to erect. Turnkey adds everything the shell kit doesn’t include: the foundation slab, professional shell erection, electrical, plumbing, HVAC, and the full interior finish package. For a 40×60 shop-house, the turnkey scope also covers the shop-specific elements your plan calls for — overhead doors, sidewall insulation or conditioning, electrical service to the shop, and any specialty flooring — coordinated through our vetted contractor network where coverage exists.
The process
How Turnkey Delivery Works
Turnkey delivery runs in four stages. We coordinate the vetted contractors at each one, so you manage one process instead of a dozen subcontractors.
FAQ
Frequently Asked Questions
How much does a 40×60 barndominium cost?
The shell kit starts from $67,200 (from $28/sqft across 2,400 sqft). A turnkey finished 40×60 barndominium starts from $276,000, with the full national range running $276,000–$480,000 depending on finish level, shop spec, and location. See the cost page and your state page for regional pricing.
Is a 40×60 barndominium big enough for a family?
Yes — in the default shop-house split, the living side runs 1,200–1,400 sqft supporting 2–3 bedrooms and 2 bathrooms with an open kitchen and great room; in the all-living configuration, the full 2,400 sqft supports 3–4 bedrooms and 2–3 bathrooms, which is a complete single-story family home.
Can a 40×60 fit a shop and a full home?
Yes — that’s the defining feature of this footprint. The 40×60 splits into roughly 1,200–1,400 sqft of living (2–3 bedrooms, 2 bathrooms, open kitchen and great room) alongside a 2-bay shop, with both sides at full working scale rather than one compromised to fit the other.
How big is the shop in a 40×60 barndominium?
In the standard shop-house split, the shop side runs roughly 1,000–1,200 sqft — wide enough for two full-size trucks or one vehicle plus serious workshop space, with sidewall height and overhead-door count set in your custom plan. A mostly shop layout can allocate more floor area to the shop if your living needs are compact.
Can I get a 40×60 as a custom design?
Yes — every Oak and Iron Kits build is a custom design, not a stock floor plan. The 40×60 footprint is the starting point; your plan sets the shop/living split, wall placement, sidewall height, door spec, loft addition, finish package, and site-specific details.
