Metal Buildings & Barns
Almost Every Hill Country Property Needs One
If you own acreage out here, sooner or later you need somewhere to keep equipment dry, livestock sheltered, or vehicles out of the weather. CMW has been putting up metal-frame structures across the Hill Country since 1999 — barns, storage buildings, carports, and detached garages sized and sited for how you actually use your land.
A metal building crew from San Antonio or Austin doesn’t know your terrain, your soil, or your local permitting requirements. Jimmy Stewart and his crew are based right here in Spring Branch, and every structure we build accounts for the ground it’s going on, not a generic spec sheet.
How a CMW Metal Building Project Comes Together
Site conditions and intended use drive every decision on a metal building project. Here's how we work through it.
-
1
1. Site Visit & Use Assessment
Jimmy walks your property to evaluate the ground, drainage, and access, and talks through exactly what the structure needs to do — livestock, equipment, storage, or a vehicle bay.

2. Sizing & Detailed Proposal
We size the structure to its actual purpose rather than a stock template, and hand you a clear, itemized proposal covering the foundation, framing, and finish-out.

3. Foundation & Frame Construction
Jimmy's crew handles the slab, the steel frame, and the exterior finish on-site, working around your land's terrain and drainage rather than fighting it.

4. Final Walkthrough & Warranty
We check every door, every seal, and every connection point before calling it finished, and back the structure with our workmanship warranty.

A Note from Jimmy
“A barn or storage building isn’t glamorous, but it has to work exactly right for years without a second thought. I’d rather spend an extra hour on your site figuring out drainage and grading than hand you a building that floods or settles wrong in five years.”
— Jimmy Stewart, Founder & Owner, CMW General Contractors
Metal Building FAQs
Questions Hill Country landowners commonly ask before adding a barn or storage building.
It depends entirely on what you’re storing or housing — a single vehicle carport looks nothing like a hay barn or an equipment shed. Jimmy walks your property during the consultation and sizes the structure to its actual purpose rather than steering you toward a stock size that doesn’t quite fit.
In most cases, yes — a proper slab or pier foundation keeps the structure stable and protects against moisture and settling, especially on Hill Country terrain with rocky or uneven ground. CMW handles the foundation work as part of the full build rather than subcontracting it out separately.
Yes — this is one of our specialties. If you already have a standing metal structure on your property, CMW can assess whether it’s a good candidate for conversion into a barndominium-style living space. Visit our Barndominiums page for more detail on how that process works.
A standard storage building or carport can often be completed in a matter of weeks, while a larger barn or multi-use structure may take longer depending on size and site prep. CMW gives you a realistic timeline in your proposal based on the specific structure and site conditions.
It depends on your county, your property’s zoning, and the size and use of the structure. CMW is familiar with the permitting requirements across the Hill Country counties we work in and handles that process as part of your project.
Yes — that’s essentially what a barndominium is. A steel-frame structure can absolutely be finished out as a fully custom home. If that’s the goal, take a look at our Barndominiums page, which covers that specific type of project in more depth.
