60×100 · custom-designed
60×100 Barndominium
A 6,000 sqft (60 ft × 100 ft) custom steel barndominium designed for serious work — fleet operations, contractor HQs, light-industrial, and working farms — with attached onsite living quarters. Shell kits ship from $28/sqft nationally; turnkey delivery via our vetted contractor network where coverage exists. We design custom plans, not stock floor plans.
Pricing
How Much Does a 60×100 Barndominium Kit Cost?
The shell kit for a 60×100 starts from $168,000 — that’s the engineered steel frame, roof and wall panels, fasteners, and hardware, delivered to your site at $28/sqft across the 6,000 sqft footprint. Turnkey starts from $690,000, with the full national blended range running $115–$200/sqft, all-in across the complete footprint.
Occupancy class is the single biggest cost variable on a commercial live-work build. The moment any portion of the structure is used commercially, a different set of code requirements follows: fire-rated separation walls between the residential and commercial zones, commercial-grade plumbing and electrical (potentially including 3-phase service), separate egress paths, and ADA compliance for any customer-facing commercial space. These requirements are jurisdictional and vary meaningfully — rural counties in the Midwest and South often have lighter commercial permitting loads than suburban or mountain-West markets — so the permitting cost alone can swing the total budget substantially. Your custom quote should be built with your county’s occupancy classification in hand.
The commercial bay’s configuration is the second-biggest cost driver. Overhead-door count and spec (standard, RV-height, or heavy-equipment-width), sidewall height, whether the commercial zone is conditioned or unconditioned, mezzanine or work-platform structure over the bay, and 3-phase electrical service all carry real cost. A minimally finished commercial shell and a fully conditioned, mezzanine-equipped contractor HQ sit at very different points in the range. On the residential side, finish level — from builder-grade to custom cabinetry and tile — moves the number further.
Site-specific costs on a live-work build are also elevated relative to a pure residential barndominium: utility runs must be sized for commercial occupancy, septic systems may need commercial-rated capacity, driveway and apron work must accommodate trucks and trailers, and any customer-facing facade (signage, parking, exterior lighting) adds to the total. Geography is the final compounding variable: rural Midwest and Southern markets sit at the low end of the national range; rural Northeast, mountain West, and Pacific Northwest sit at the high end.

What fits
What Can You Fit in a 60×100 Barndominium?
In the default live-work configuration, a 60×100 splits into roughly 1,500–2,000 sqft of residential living — supporting 2 bedrooms, 1.5 bathrooms, an open kitchen and living area, utility space, and a separate exterior entry — and 4,000+ sqft of commercial or working bay space. That commercial half is large enough for fleet vehicles, a contractor headquarters with onsite workshop, small-business retail with a workroom and stockroom, light-industrial assembly or storage, working-farm processing and machinery, or any use that benefits from clear-span steel structure with overhead-door access.
The residential side functions as a genuine apartment, not a bunkroom. With 1,500–2,000 sqft and its own exterior entry, the living quarters can serve as a primary residence for the business owner, a manager’s apartment, or an employee dwelling — physically separate from the commercial zone with a fire-rated separation wall between the two. Sidewall height, overhead-door specification, and commercial-grade plumbing and electrical configuration are all custom to your build and your occupancy classification.
The estate-residence layout at the other end of the spectrum uses all 6,000 sqft as a single-story home: 5–6 bedrooms, 4–5 baths, dedicated wings (kids, master, guest, in-law), formal dining, library or office, a vaulted great room, butler’s pantry, and multiple covered porches. The large shop-house layout splits the footprint roughly 3,500 sqft of living (4–5 BR, 3 BA) over a 2,500 sqft 5-bay shop with RV and equipment bays. A fourth configuration keeps about 5,000 sqft as finished living with a 1,000 sqft 2–3 bay attached garage. Each of these is a custom plan drawn around your household and site.
The 60×100 advantage
The Only Size in the Cluster That Crosses Occupancy Class — Commercial Bay with an Attached Apartment
Every other size in the Oak and Iron lineup is a residential structure, even when it carries a large shop. The 60×100 is different: at 4,000+ sqft of working bay, the commercial side is large enough to function as a genuine business premises — licensed contractor HQ, fleet-vehicle storage, light-industrial production, farm-processing facility — while the attached 1,500–2,000 sqft apartment keeps you or your employees onsite around the clock. That is a fundamentally different product from a residential barndominium with a big garage.
No smaller size in the cluster delivers this combination. The 50×100 at 5,000 sqft is the cluster’s large homestead — it is still a residence with a shop. The 60×80 at 4,800 sqft is a wide, single-story family home. The 60×100’s extra 1,000–1,200 sqft over those neighbors — and more importantly, the way that footprint is allocated — is what allows one zone to clear commercial occupancy thresholds while the other remains a legal dwelling. That distinction matters for permitting, financing, and long-term business use.
Layouts
How a 60×100 Can Lay Out
We design custom plans — not stock floor plans. The 6,000 sqft footprint runs from a full commercial live-work split to an all-living estate home, drawn around your household, your operation, and your site.
The same 60×100 shell runs the full range — from Estate (all-living) to Live-work, and anywhere in between. These are common starting points, not fixed plans. Every 60×100 we build is custom-drawn from scratch.
Drawn to scale. The living-to-shop split shown is just one of many possible layouts — every 60×100 is designed from scratch.
The live-work split is the default configuration and the reason most buyers choose a 60×100. The residential and commercial sides can be reconfigured within the footprint — a 30/70 split gives you more commercial bay and a compact apartment; a 50/50 split gives you a generous 3,000 sqft home alongside a substantial 3,000 sqft working floor. Common additions to the commercial side include a mezzanine or second-floor office overlooking the bay, 3-phase electrical service, commercial-grade plumbing (floor drains, utility sinks, restroom for employees or customers), RV-height or oversized overhead doors, and fire-rated separation walls between zones. Conditioned vs. unconditioned commercial zones is a meaningful decision: conditioning the bay for year-round work adds to operating cost but makes the space usable for production, fabrication, or customer-facing retail in any climate.
The estate-residence layout — all 6,000 sqft as a single-story home — suits buyers who want maximum residential square footage in a single-story steel structure. At this footprint, your plan can include dedicated wings, a vaulted great room, formal dining, a butler’s pantry, library or home office, and multiple covered porches with room to spare. The large shop-house (roughly 3,500 sqft of living plus a 2,500 sqft 5-bay shop) delivers a full family home alongside a genuine multi-vehicle shop with RV bay. Buyers drawn to an all-living or shop-house layout who find the 60×100 scale larger than they need should also consider the 60×80 — the wide single-story family home in the cluster — which offers the same 60 ft width in a tighter, more efficient footprint.
Best for
What a 60×100 Barndominium Is Best For
The 60×100 is best for small-business owners, fleet operators, light-industrial users, working farms, and rural artisans who need substantial commercial-grade working space with attached onsite living quarters — not a residential build with a big garage, but a genuine business premises with a legal dwelling attached.
Small-business owners running a fleet — landscaping, HVAC, plumbing, electrical, delivery — find the 4,000+ sqft bay large enough for vehicle storage, parts inventory, and a service area, while the attached apartment eliminates the commute and keeps someone onsite. Contractors and trades professionals use the 60×100 as a real HQ shop: bays for equipment and vehicles, a workshop and parts room, a client-facing entrance, and an apartment for themselves or a live-in employee. The mezzanine or second-floor office option makes the commercial zone feel like a real business address.
Working-farm owners use the commercial bay for machinery storage, livestock operations, or crop processing and farm-stand retail, with the residence serving as the primary farmhouse. Rural artisans — woodworkers, metal fabricators, custom builders — running a serious production studio benefit from the clear-span steel structure, large overhead-door access, and the ability to condition all or part of the bay for year-round work. E-commerce and warehousing operators who need bulk storage alongside compact living quarters round out the buyer profile. If your primary need is residential — even with a large shop — the 50×100 is likely a better fit.
Size comparison
60×100 vs. Other Sizes
| 60×100 | 50×100 | 60×80 | |
|---|---|---|---|
| Footprint | 6,000 sqft | 5,000 sqft | 4,800 sqft |
| Turnkey range | $690,000–$1,200,000 | $575,000–$1,000,000 | $552,000–$960,000 |
| Best for | Commercial live-work, fleet ops, light-industrial | Large homestead, 4-bay shop-house | Wide single-story family home |
The 60×100 is the only commercial live-work size in the cluster — the comparison with its neighbors is not just a matter of square footage but of occupancy class. The 50×100 at 5,000 sqft is the cluster’s large homestead: a residential build with a serious 4-bay shop, designed and permitted as a residence. The 60×100’s extra 1,000 sqft — and how that footprint is allocated — is what allows one zone to cross the residential-to-commercial threshold, which changes permitting, plumbing, electrical, and fire-separation requirements in ways that 5,000 sqft of residential-with-shop does not trigger.
The 60×80 at 4,800 sqft shares the 60 ft width with the 60×100, making it the structurally similar residential counterpart: same wide footprint, shorter depth, used as a large single-story family home rather than a business HQ. Buyers drawn to the 60×100 for its estate-residence layout option — but who don’t need the commercial bay — should look seriously at the 60×80 first, which delivers the wide single-story structure in a tighter, more efficiently priced footprint.
Kit or turnkey
Kit or Turnkey: How Most Buyers Build a 60×100
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, and hardware — everything needed to stand the structure on a prepared slab. It does not include the foundation, erection labor, fire-rated separation walls, commercial plumbing and electrical rough-in, HVAC, or interior finish for either zone. Turnkey delivery via our vetted contractor network adds all of that in a single coordinated process — critical on a live-work build where residential and commercial trades must be sequenced together and where commercial-occupancy inspections require coordination between the two zones. Turnkey is available where coverage exists; your quote will confirm network availability in your market.
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 — especially important on a commercial live-work build where residential and commercial permitting, inspections, and trades must stay in sync.
FAQ
Frequently Asked Questions
How much does a 60×100 barndominium cost?
The shell kit starts from $168,000 ($28/sqft across 6,000 sqft). Turnkey — fully built and move-in ready — starts from $690,000, with the national blended range running $115–$200/sqft all-in across the full footprint. Commercial live-work builds sit toward the upper end of that range because of fire-separation requirements, commercial-grade electrical and plumbing, and occupancy-specific permitting costs that don’t apply to a standard residential barndominium.
Can a 60×100 barndominium be used for commercial purposes?
Yes — and it’s the only size in the Oak and Iron cluster specifically designed to support commercial occupancy alongside residential. The commercial zone can support fleet-vehicle storage, contractor workshops, light-industrial assembly, small-business retail with stockroom, or farm-processing operations. Once commercial occupancy applies, fire-rated separation walls, commercial-grade plumbing and electrical, separate egress, and ADA compliance for public-facing areas are required — all of which your custom plan and local permits will address.
What’s the difference between a 50×100 and a 60×100 barndominium?
The 50×100 is a 5,000 sqft residential barndominium with a large shop — designed, financed, and permitted as a home. The 60×100 is a fundamentally different product: its extra 1,000 sqft and the way the footprint is allocated allow one zone to cross the residential-to-commercial occupancy threshold, which changes permitting, fire-separation requirements, plumbing, electrical, and long-term financing options in ways the 50×100 does not trigger.
How big is the apartment side in a 60×100 live-work build?
In the default live-work configuration, the residential side runs 1,500–2,000 sqft — enough for 2 bedrooms, 1.5 bathrooms, an open kitchen and living area, utility space, and a separate exterior entry. The split can be adjusted within the footprint: a 30/70 allocation gives a more compact apartment alongside a larger commercial bay, while a 50/50 split yields about 3,000 sqft of living alongside 3,000 sqft of working floor.
Can I get a 60×100 as a custom design?
Yes — every Oak and Iron build is a custom plan, not a stock floor plan. Your 60×100 is drawn around your operation, your household, and your site: residential-to-commercial split ratio, overhead-door count and spec, mezzanine or second-floor office configuration, conditioned vs. unconditioned bay zones, 3-phase electrical, and exterior facade and signage options are all part of the design conversation.
