Why Steel Makes Sense
Durability & Longevity
Steel avoids rot, warping, mold, and pest damage—unlike wood—resulting in far lower lifetime maintenance requirements.
Superior Structural Strength & Longevity
Engineered steel maintains integrity under heavy loads, machinery weight, pallet racks, and long-term operational stress.
Clear-Span, Unobstructed Workspace
No interior columns interrupting tool placement, equipment staging, vehicle paths, or processing lines.
Cost Efficiency & Quick Build Times
Prefabricated steel systems arrive pre-cut, pre-punched, and ready for rapid assembly, reducing delays and labor costs.
Low Maintenance Over Decades
Steel requires far less upkeep than wood or mixed-material structures, avoiding repainting, termite treatment, and rot mitigation.
Flexibility & Scalability
Designed for expansions, mezzanine additions, retrofits, or workflow changes with minimal structural disruption.
You're not just buying a building — you're buying a solution that lasts.

Sub-Categories
Barndominium (Full Home)
Use Cases
Ideal for: People wanting a spacious, durable, low-maintenance home — often in rural or semi-rural areas.
Design Considerations
- Full HVAC, residential plumbing/electrical, insulation, compliance with residential codes, comfortable finishes.: a barndominium gives you “home comfort + steel durability.” A shop-house adds “workspace flexibility” — but requires thoughtful planning around insulation, ventilation, and slab spec.
Shop-House (Residence + Workshop / Garage)
Use Cases
Ideal for: Owners who want live/work flexibility: hobbyists, small business owners, mechanics, craftsmen.
Design Considerations
- Separate conditioned “home” areas from unconditioned/heavy-use “shop” zones; slab and foundation thickness; ventilation and flooring for shop work; sound isolation.:
What Makes Mammoth Different
We erect what we sell — no middleman, no surprises. You get the structural kit + real erection team, handled by crews familiar with snowloads, Colorado winds, and local codes.
Pre-construction design review — we catch potential issues (foundation, door placement, shop-house transitions) before drawings go to engineering.
Customized layouts & realistic build planning — we design for how you actually live and work: separate shop slab, HVAC zoning, insulated living space, proper roof/wall insulation, and energy considerations.
Transparency on cost drivers — we’ll walk you through what adds cost (eave height, insulation levels, door/garage type, slab thickness), so you make informed decisions — not get blindsided.
Typical Features & Options
- Clear-span steel framing allowing open floor plans or “open shop + living loft” layouts.
- Variety of roofing and siding colors/options — giving “home-like” exterior rather than “industrial warehouse.”
- High-quality insulation and ventilation systems for energy efficiency and comfort.
- Mixed-use readiness: shop zones with proper slab and ventilation; living zones with HVAC, windows, desired finishes.
- Future-ready design — easy to expand or modify (e.g. add mezzanine, expand shop, change configuration) thanks to steel’s flexibility.
Cost Drivers
- • Eave height & roof pitch — higher eaves = more steel, higher cost.
- • Insulation & finish level — bare-bones steel shell vs. full residential-grade finish (insulation, HVAC, interior walls, flooring, windows).
- • Foundation / slab specs — shop-heavy use demands thicker slab, possibly footings or slab-on-grade with frost protection — not the same as a simple metal shed.
- • Door & opening types — overhead doors, roll-ups, full-size entries, insulation around doors — these add cost and complexity.
- • Mechanical, plumbing, electrical setup — living spaces need full systems; shop zones may require heavy-duty circuits and ventilation.
Process & Timeline
Discovery & Use-Case Planning
Establish intended use, livability requirements, shop integration, and any planned future expansions.
Preliminary Building Layout & Design Review
Draft conceptual layout, evaluate slab requirements, mechanical placement, insulation needs, door locations, and egress planning.
Engineering & Permit Documents
Produce sealed structural drawings and specifications required to meet local building codes and secure permits.
Order & Delivery of Metal Building Kit
Coordinate fabrication and shipment of the complete metal building package including framing, panels, trim, and accessories.
Foundation / Slab Preparation
Execute foundation and slab work through customer’s contractor or third party, aligned and scheduled with building delivery and erection.
Erection by Mammoth Crews
Assemble steel structure, roof, and exterior shell rapidly and professionally — typically completed in days rather than months.
Finish-out (Interior, HVAC, Plumbing, etc.)
Customer or subcontractors complete interior systems such as HVAC, plumbing, partitions, insulation finishes, and livability upgrades.
FAQ
Are metal barndominiums “cold” or hard to heat?
Not when properly insulated. Modern insulation systems, HVAC zoning, and vapor barriers provide comfort equal to or better than conventional homes.
Will a metal home feel too “industrial”?
Not with thoughtful design. Exterior panel choices, trim profiles, window packages, and interior finishes create any aesthetic — rustic, modern, farmhouse, or traditional.
Are barndominiums allowed under residential building codes?
Yes — provided the plans meet local code requirements for foundation, egress, insulation, and structural loads. We handle the engineering and permitting to ensure compliance.
Can I expand later if I need more shop or living space?
Absolutely. Steel offers one of the most expansion-friendly structural systems — adding bays, reconfiguring interiors, or integrating mezzanines is straightforward.
