Modern, Affordable Residential Steel Buildings
Factory-Direct Metal Arch Home Kits Backed by a 35-Year Warranty
Whether you are a contractor building inexpensively in volume or a homeowner ready to build the steel arch home you have always pictured, ArchBuildings.com delivers everything you need in one easy-to-assemble kit. From compact tiny homes, ADUs and guest cottages to full-size barndominiums, steel cabins, and family metal arch houses, our clear-span kits are creative, modern, and built to last.
Why Homeowners Choose Steel Arch Buildings
Strong, energy-smart, and dramatically more affordable than stick-built homes.
Up to 50% Lower Shell Cost
Our residential steel arch kits ship factory-direct and eliminate the framing, trusses, and waste of conventional construction. Many owner-builders cut shell costs by 30% to 50% compared to a traditional stick-built home of the same square footage, freeing up budget for the interior finishes that matter most to you.
DIY-Friendly Assembly
Building your steel arch home kit yourself saves money, builds real ownership, and lets you control quality at every step. Each kit ships with a detailed installation manual that walks you through construction with tips and tricks for a sturdy, beautiful finish — perfect for owner-builders and contractors alike.
Built to Last with Galvalume
Every kit is made from premium Galvalume steel paired with grade-8 hardware. Galvalume's aluminum-zinc coating resists rust, mold, mildew, fire, termites, and high winds — giving your metal arch home a maintenance-light envelope that outlives traditional siding.
Open, Column-Free Living
The 100% clear-span arch design means no interior load-bearing walls — so you can lay out your steel cabin, barndominium, or family home exactly how you want it. Add lofts, vaulted ceilings, open kitchens, or a workshop wing without restructuring the shell.
Designed for the Way You Want to Live
A steel arch home is not a compromise — it is a creative platform. The arch shell gives you a finished exterior in days, then you build out the interior with the same finishes you would expect in any home: drywall, hardwood, tile, custom kitchens, fireplaces, lofts, and outdoor patios.
Homeowners use our residential kits for full-time houses, vacation steel cabins, barndominiums that combine living space with a shop or garage, backyard ADUs and guest houses, pool houses, and modern tiny homes. Whatever the use case, the clear-span arch gives you room to grow.
With founders carrying over 30 years of experience in the steel arch building industry, ArchBuildings.com brings you three proven styles in easy-to-assemble kit form — engineered to your local snow, wind, and seismic loads.

Residential Steel Arch Building FAQ
Answers to the questions homeowners ask most.
Can you really live in a steel arch building?
Absolutely. Thousands of homeowners use steel arch buildings as full-time residences, vacation cabins, guest houses, ADUs, and barndominiums. With insulation, interior framing, plumbing, and finished surfaces, a steel arch home is just as comfortable as conventional construction — and often more energy-efficient.
Are steel arch homes more affordable than traditional houses?
In most cases, yes. Factory-direct pricing, the elimination of trusses and conventional framing, and reduced material waste mean many owner-builders save 30% to 50% on shell cost compared to a stick-built home of the same square footage.
Can I get a building permit for a steel arch home?
Yes. Our residential kits are engineered to meet local snow, wind, and seismic loads. If your jurisdiction requires stamped engineered drawings for permitting, just ask your sales representative and we will provide them for your project.
What sizes are available for steel arch homes and barndominiums?
Our Style A, Style S, and Style Q residential kits are available in widths from 20 feet up to 100+ feet of clear-span interior space, in any length you need — perfect for everything from a backyard ADU to a sprawling barndominium.
How long does it take to build a residential steel arch kit?
A small crew can typically erect the arch shell in a few days to a couple of weeks, depending on size. Interior build-out (insulation, framing, plumbing, electrical, finishes) is comparable to any home and varies with your design choices.
