What We Build
Every NatMar build starts the same way: you tell us what it's for, we tell you what it takes. Browse by category to see specs, lead times, and recent projects.
Barns, livestock shelters, riding arenas, equipment storage
Steel ag buildings hold up to weather, animals, and decades of hard use. We design and erect barns, run-ins, free-stalls, riding arenas, hay storage, and equipment buildings on Western Slope ranches and farms.

Warehouses, distribution, light manufacturing, retail
Warehouses, distribution, light manufacturing, factories, hangars, dockyards, offices, arenas — if it's commercial and it's made out of steel, we build it. Faster up, fewer interior columns, and lower cost per square foot than wood-frame or block. Headquartered in Grand Junction and Delta, working across the Western Slope and available to advise nationwide.

Mechanic shops, hobby shops, home garages — your space, your rules
Hobby shops, mechanic shops, home garages — the place you spend Saturdays. Wide clear spans, tall doors for lifts and tractors, insulated walls for year-round use, and electrical rough-in planned around how you actually work. Single, double, or triple bay.

Steel-framed living — open plans, shop attached, lifestyle ready
A barndominium is steel-framed, finished living space — often with an attached shop, garage, or arena. Wide open floor plans, fewer interior walls, and serious build quality at a price below traditional stick-built homes.

Cover for vehicles, equipment, and seasonal storage
From a simple two-post carport to a fully enclosed multi-bay garage. We size to your vehicle (or your collection), add side walls when you want them, and finish to match your home or shop.

Aircraft hangars from single-engine to corporate twins
Aircraft need clear span, tall doors, and a floor without columns in the way. We build T-hangars, box hangars, and corporate hangars for private owners and small operators on the Western Slope. Red iron is usually the answer when eaves need to clear a tail or the door opening pushes past 40 feet.

Self-storage facilities — single-row to multi-building campuses
Self-storage is one of the fastest-permitting commercial uses in most counties. We've built single-row 5×10 unit blocks and multi-building campuses with climate-controlled bays. Fast lead time, low operating cost, predictable revenue.

Tall, wide, weather-protected covered storage
RVs, boats, and toy haulers need taller doors, wider bays, and protection from snow and UV. We design RV/boat storage facilities sized for the largest Class A motorhomes and 5th-wheels.

Compact storage buildings — built once, lasts decades
When you need a backyard storage building that won't rot, won't need painting, and won't need replacing in 10 years, steel is the right answer. We build sheds from 10×12 up to 20×40 for residential and small commercial.

Accessory dwelling units — steel-framed, finish-ready living space
An ADU is a detached or attached living unit on a property that already has a primary home. We build them in steel — typically with our FrameCad panelized cold-formed system — for finished interiors that pass framing inspection square the first time. Guest house, rental income, multi-generational living, or office space, all in a steel envelope that outlasts stick-built.

If you can dream it, we can build it
Sometimes a project doesn't fit a standard category. Equestrian arenas with attached living quarters. Wineries with tasting rooms. Custom barns with finished offices. Multi-use buildings that combine workshop, storage, and event space. We build those too.

Workshop
Tall American barn-style shop — long footprint for multi-bay layouts, high ceiling for lifts, vertical storage, or hobby work that needs serious clearance.

Carport / Garage
Single-bay garage with full-height overhead door — sized for a full-size truck, RV, or compact workshop.
Agriculture
Open-sided ag layout with a single-slope roof — sized for hay storage, equipment cover, or animal shelter with quick drainage and clean snow shed.
Testimonials
“Nate and his experienced crew did a fantastic job erecting our 35' x 40' steel shop. I found NatMar through an internet search. I selected NatMar because they were local, displayed excellent expertise, and were competitively priced. Their communications and administration were flawless. The crew was always punctual, polite, and worked with care and attention to detail. We had some challenges along the way; however, everything was dealt with without any fuss or penny-pinching.”
“Nathan and his crew are top notch! They were able to fit in my small project between their bigger jobs which got me finished real quick. They do great quality work and I would highly recommend NatMar to anyone.”
“Complete project was good quality, on time, on budget and craftsmen were very professional. If I could find anything not perfect would be the screws scattered around post completion which is petty. Great job guys!”
