What We Build
Post-frame for every purpose
One method, countless applications. Every structure is custom-designed for your site, your use case, and your budget.
View all servicesEquipment storage, hay barns, and working farm structures built for the demands of Colorado ranch life. We design around your workflow — how you move equipment, store feed, and manage your property day to day.

Custom stall configurations, full riding arenas, and equestrian structures designed around how you work with your animals. Sliding barn doors, dutch doors, and custom clearances all available.

Residential and commercial storage in any size or configuration. Simple, durable, and built to last — with door placements, clearances, and add-ons tailored to exactly what you're storing.

The perfect space for your tools, toys, and passions. We design around how you actually plan to use the space — mezzanine lofts, workshop layouts, oversized doors, and every finish detail.

Oversized bays for vehicles, campers, boats, and equipment — built with the clearance and door configurations you need. RV height doors, pull-through bays, and custom widths all available.

Functional, durable commercial space for businesses across Northern Colorado — warehouse, office, or combined. Fully permitted, owner-operated builds at a price point that works for your business.

Post-frame homes for clients who want the character, durability, and value of metal construction in a custom living space. Open floor plans, wraparound porches, and Central States metal throughout.

We supply and install Amarr overhead doors — high-grade steel, robust designs, and the best insulation ratings available. Residential, agricultural, and commercial.

Protect Your Investment
Keep your posts out of the ground
Traditional post-frame construction buries a treated wood post directly in the ground. That post may last 50 or even 100 years — but eventually, it will rot. It is the single biggest long-term vulnerability in a post-frame building.
We offer permanent foundation solutions using Permacolumn Sturdi-Wall brackets — a concrete pier and steel bracket system that holds the post above grade, eliminating all ground contact and any possibility of rot. Backed by a lifetime warranty and engineered for both durability and longevity.

Common Questions
The loft files
Est. 2023 — Platteville, CO
Most shop and garage builds are completed in 2–4 weeks once materials are on site. Barndominiums with interior finishing can take 3–6 months depending on scope. We give you a realistic timeline before we ever break ground.
Yes. We work with local counties across Northern Colorado to pull the necessary permits and can coordinate stamped engineering drawings for your project. We handle the paperwork so you can focus on the build.
We serve Weld, Larimer, Boulder, and Morgan counties — covering Fort Collins, Greeley, Loveland, Windsor, Longmont, Fort Morgan, and surrounding rural communities. Give us a call and we'll let you know if we can get to you.
Absolutely — every project we build is custom. We work with you from the ground up to design a structure that fits your land, your needs, and your budget. No cookie-cutter kits here.
Post-frame (also called pole barn construction) uses large laminated columns buried in the ground or anchored to a foundation, which eliminates the need for a full concrete perimeter. It's faster, more cost-effective, and incredibly strong — ideal for large clear-span spaces like shops, garages, and barndominiums.
Yes. Our overhead door division works independently of new construction. We can supply and install commercial and residential overhead doors on existing structures across Northern Colorado.
