How Buyers Configure a Barndominium Shell
Same clear-span engineering, four common layouts.

Farmhouse-Style Finish
Standing-seam metal roof, black window trim, and a glass sunroom addition off a covered porch — an example of the finished exterior a barndominium shell can carry once your local contractor completes the porch, siding, and windows.

Classic Red Barn Exterior
The barndominium look doesn't have to mean neutral tones or a farmhouse-scale footprint. This example is finished in traditional red with a white metal roof and a covered side porch — a smaller, single-story shell that still reads unmistakably as a barn. Exterior color and porch style are entirely up to you and your finish contractor.

40x60 Large-Format Shell
The larger of Northcraft's two most common barndominium footprints — still C-channel and clear span. Going longer at the same 40-foot width (40x80, 40x100) stays C-channel too; it's going wider than 40 feet that moves a project to I-beam. Enough footprint for a larger home, a full workshop, and multi-vehicle storage under one roof.

Garage-Forward Layout
Some buyers lead with the garage — RV bay, workshop, boat storage — and finish a smaller living footprint inside the same shell. The framing doesn't care which side is bigger; the engineering is the same either way.

Frequently Asked Questions
What does a steel barndominium shell cost?
Northcraft's published floors for the barndominium size range start at $17,300 for a 30x40, delivered, scaling up in size through a 40x60, at a 10-foot eave height with standard loads. That's the structural shell only — engineered drawings, components, and freight. Interior finish-out (walls, plumbing, electrical, flooring) is a separate project most buyers contract locally.
Does the price include finishing the interior into a home?
No, and no honest steel building supplier's price does. Northcraft's floor covers the engineered structural shell: framing, roof and wall panels, and the drawings your permit office needs. Turning that shell into livable space — insulation, drywall, plumbing, electrical, flooring — is finish-out work, typically done by a local general contractor.
Why does the price depend on the footprint?
Because a barndominium isn't one size. Northcraft's most common barndominium footprints, 30x40 and 40x60, are both clear span and both C-channel framing, but the larger footprint costs more. Your exact number depends on which footprint you choose, your eave height, and your state's code requirements. See the 30x40 and 40x60 pages for the specific floor at each size.
Can a barndominium be bigger than 40x60?
Yes, in two ways. Longer at the same 40-foot width stays C-channel — 40x80 and 40x100 are both priced in C-channel (see the 40x60 page for those floors). Wider than 40 feet moves the frame to I-beam, a different, heavier system with its own price basis (and a 12-foot eave basis rather than C-channel's 10-foot) — Northcraft's I-beam floor starts at $29,800 for a 50x50. Tell us your target footprint and we'll quote it on the right basis rather than guessing from the C-channel range.
What loads does the published price assume?
The floors above assume ground snow load up to 35 lb per square foot and wind speed up to 110 mph. If your county requires more, that moves the price — tell us your zip code and we'll confirm your real number. Barndominium shells this size are C-channel, sized for residential use, and typically don't carry the kind of collateral load (a crane, heavy mezzanine) that affects Northcraft's larger I-beam buildings — a finished ceiling and normal HVAC for living space don't change the structural shell price.
Do I need a permit for a barndominium?
Most jurisdictions require a permit, both for a structure this size and for residential living space. We provide the stamped engineering drawings; permitting for the residential occupancy and finish-out is handled through your local process, same as any home construction project.
Can I customize the barndominium, or are these fixed sizes?
Every Northcraft building is fully customized to your exact specifications — the 30x40-40x60 range isn't a catalog of fixed layouts. If you already have your own floor plan, tell us your dimensions and door, window, and porch placement, and we'll engineer to those specs rather than a preset.
Is a steel barndominium shell a DIY project?
The 30x40 shell is a realistic project for an experienced DIY crew with the right tools; a 40x60 generally needs a professional erector for the larger spans and heavier components. Either way, the interior finish-out (electrical, plumbing, insulation) is specialized work that's rarely DIY. Our buyers' guide covers the erection trade-offs in more detail.
How does a barndominium compare to a traditional pole-barn conversion?
A steel-framed shell and a wood pole-barn conversion solve the same problem differently. Pole barns have gotten more expensive as lumber and skilled framing labor costs have risen — a comparable wood structure can now run at or above a steel equivalent. See our pole barn comparison post for the real numbers on both sides.
