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
    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
    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
    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.

This is our second project with CMW. This time they built our forever home for us. We've been living in our barndominium for 3 months and couldn't be happier with it. The process was smooth, the quality and customer service outstanding. Honest, patient, trustworthy. We don't hesitate to recommend Jimmy and Chandler at CMW.

If we could give more stars, we would! We have been in our custom home for 6 months now and we are so pleased with the end result. Jimmy and Chandler could not be more reliable and trustworthy, which was very important to us as 75% of our home was built while we lived in another state. From start to finish all communication was timely, all materials are of high quality, and the custom touches throughout our home were thoughtful and well done. Jimmy is a seasoned contractor with excellent instincts and advice, and Chandler is very creative with an eye for design. It was a true pleasure working with CMW Contractors and we are looking forward to working with them again for projects in the future!

From concept to completion, CMW was with us every step of the way. We started with an idea and a drawing, and Jimmy and his team brought it to life. As a customer, I think it is natural to have some anxiety through the building process but Jimmy always kept us informed and explained the process well. We learned a lot and were able to create a unique home that is exactly what we wanted and that truly reflects us. If you want a home that is a reflection of your dream, then CMW is your contractor.

Jimmy and crew extended the steel barn roof to cover the RV pad. Did a fantastic job at a reasonable price. Would have them do any job in the future.

We really enjoyed working with Jimmy and CMW for the remodel of our barnodominium. What started as one big shell of a room became a beautiful, open living space with a bathroom, kitchen and living room and we absolutely love it! We had a few unexpected twists and turns to navigate and Jimmy was there with us every step of the way. He really went above and beyond many times during the process, and we hope to work with CMW again on future projects!

Jimmy, his crew, and family are amazing! We had them work on a remodel to our home as well as some small update jobs throughout. They were timely, kind, fair with price, had great attention to detail with good quality work, and very knowledgeable. We have three young children and they were thoughtful to our families needs and schedule as well. I would recommend them to anyone needing to repairs or renovations done to your home.

Very easy to work with. Quality work. Nice construction crew and very informative. Did a great job on our office building stucco work and found someone for us to help with new gutters. Worked on balcony tile grout until we were satisfied with the color! Would highly recommend! Jimmy is awesome and hands on!
