Metal Building vs Wood Frame Construction

The cost difference between metal and wood frame construction is the most cited reason Hill Country property owners call us — and the numbers are significant. In 2026, a basic metal building shell in Central Texas runs $15–$30 per square foot for the steel structure alone. A finished metal barndominium with insulation, electrical, plumbing, and interior finishes typically lands at $85–$145 per square foot depending on spec level. By comparison, a new wood frame custom home in Burnet or Marble Falls averages $175–$250 per square foot, with higher-end Hill Country builds reaching $300+ per square foot when custom millwork, stone exteriors, and luxury fixtures are included.

Those numbers reflect real projects we've completed. A 2,400-square-foot metal barndominium we finished near Bertram in 2024 came in at $112 per square foot fully finished. A comparable wood frame custom home in the same size range in Marble Falls ran $218 per square foot. That's a $254,400 difference on a same-size build — enough to fully fence a property, add a detached shop, or fund years of operating costs.

Material costs account for part of the gap. Lumber prices remain volatile post-pandemic, with framing lumber averaging $450–$600 per thousand board feet in 2025–2026. Structural steel pricing has stabilized, making metal more predictable to budget. Labor is another factor: metal building erection is faster, typically 30–50% fewer labor hours than wood framing for the shell, which directly reduces your cost when working with a contractor who handles both trades in-house.

Central Texas is not a gentle climate for buildings. Burnet County averages a high of 96°F in July and August, experiences hail season from March through May, and sees occasional hard freezes from December through February. These conditions expose real differences between metal and wood frame construction that national comparisons often miss.

Metal buildings rated to IBC 2021 standards handle wind loads of 90–130 mph depending on design specification — critical in an area that sees strong spring thunderstorms tracking up from the Gulf. The Metal Building Manufacturers Association (MBMA) certifies building systems to withstand these loads with engineered connections that wood framing, unless heavily strapped and braced, cannot easily match at the same cost.

Hail is where metal clearly outperforms. During the March–May hail season, 26-gauge steel panels used in quality metal roofing carry a Class 4 impact resistance rating — the highest available — under UL 2218 testing standards. Wood-framed homes with asphalt shingle roofing typically carry Class 1–3 ratings and require roof replacement every 15–25 years in Central Texas. Our metal roofing projects in Horseshoe Bay and Kingsland have documented zero hail damage claims after multiple significant hail events since installation.

For thermal performance, metal buildings require proper insulation — typically R-19 to R-30 wall insulation and R-38 roof insulation minimum to meet IECC 2021 energy code requirements for Texas Climate Zone 2. With proper spray foam or batt-and-blanket systems, metal buildings can match or exceed wood frame energy performance.

Timeline is a real differentiator for Hill Country property owners who are paying rent, living in an RV on their land, or trying to hit a specific move-in date. Based on our project history across Burnet, Liberty Hill, and Georgetown, here's what realistic timelines look like in 2026.

A metal building or barndominium from permit approval to move-in typically runs 4–7 months for a 1,500–3,000 square foot finished structure. The steel package — engineered, fabricated, and delivered — arrives in 6–10 weeks from order. Erection of the shell takes 1–3 weeks for a two-person experienced crew. Finish work (insulation, electrical, plumbing, HVAC, interior) then runs 8–14 weeks depending on complexity and sub-trade scheduling.

Wood frame custom homes in the same size range typically run 8–14 months from permit to certificate of occupancy, with high-end custom homes sometimes stretching to 18 months. Framing alone takes 3–6 weeks, but the sequential nature of wood frame construction — foundation cure, frame, sheathing, rough-in trades, insulation, drywall, finish — creates more scheduling dependencies and weather-related delays.

Permitting timelines at the Burnet County permitting office currently run 3–6 weeks for residential projects. Our experience with Burnet County plan review shows metal buildings with engineered stamped drawings typically move through review faster than complex wood frame custom plans, shaving 1–2 weeks off the front end.

For clients calling us at 830-289-3852 who need to move fast — often people relocating to the Hill Country from Austin or San Antonio — metal is almost always the faster path to occupancy.

When Hill Country property owners focus only on build cost, they often miss the 30-year cost picture — and that's where metal buildings gain significant ground. Structural steel doesn't rot, warp, crack, or attract termites. In an area with active termite pressure along the Edwards Plateau and Llano Uplift soils common in Burnet and Lampasas counties, that matters.

A wood frame home in Central Texas requires repainting every 7–10 years ($3,000–$8,000 per cycle), roof replacement every 20–25 years ($12,000–$25,000 for a 2,000 sq ft home with architectural shingles), and ongoing termite treatment contracts ($300–$500 annually). Foundation issues are also more common with wood frame construction on the expansive clay soils found in parts of the I-35 corridor near Georgetown and Leander — pier-and-beam or post-tension slab repairs can run $5,000–$30,000.

Metal buildings properly finished with Galvalume or Kynar 500 coatings carry 40-year paint warranties on some panel systems. The structural frame, when properly engineered to MBMA standards, is rated for 50+ years. Maintenance typically consists of periodic sealant inspection at penetrations and panel fastener checks — annual tasks that cost far less than wood exterior upkeep.

The Texas Department of Licensing and Regulation (TDLR) requires licensed contractors for residential construction, and we always recommend verifying any contractor's license before signing. Unlicensed work often leads to deferred maintenance issues that compound the long-term cost gap between properly built metal and wood structures.

In our 7+ years building across the Hill Country, the most consistent feedback from clients who chose metal barndominiums is that interior customization requires more planning upfront — but is absolutely achievable. Where wood frame genuinely leads is in the ease of last-minute design changes, wall repositioning during construction, and the perception of interior finish quality among traditional home buyers.

Wood frame 2x6 stud walls at 16-inch on-center spacing make it simple to run wiring, plumbing, and HVAC in any direction without coordination with the structural system. In a metal building, interior partition walls are typically wood-framed inside the metal shell — so finish carpentry, cabinetry, and trim work are identical to a wood frame home once you're past the exterior.

For resale, wood frame custom homes in Marble Falls, Georgetown, and Horseshoe Bay consistently command higher per-square-foot prices in the MLS, particularly in established neighborhoods with deed restrictions favoring traditional construction. A barndominium on rural acreage may appraise well, but in a platted subdivision, metal exterior construction sometimes faces HOA restrictions or appraiser familiarity issues.

The hybrid approach — metal exterior frame with wood-framed interior partitions and a fully custom interior finish — is increasingly common in our builds. This captures the durability and cost advantages of metal structure while delivering the interior flexibility that wood frame buyers expect. Several of our Liberty Hill and Georgetown projects have used this approach successfully.

Navigating Texas Hill Country permitting is one area where having a local contractor with direct experience saves time and money. Permitting requirements vary significantly between incorporated cities and unincorporated county land — and the Hill Country has a mix of both.

In unincorporated Burnet County, residential construction is governed by the International Building Code (IBC 2021) and International Residential Code (IRC 2021) as adopted by the state of Texas. The Burnet County permitting office requires engineered drawings for metal buildings over 200 square feet, a site plan showing setbacks from property lines (typically 25 feet front, 10 feet side and rear for residential in most zones), and a TDLR-registered contractor of record for residential projects.

For metal buildings, the MBMA-certified engineered package that comes with quality steel building systems — including anchor bolt plans, frame drawings, and load calculations — satisfies most of Burnet County's structural documentation requirements. This is an advantage over custom wood frame, which requires a separate structural engineer to produce equivalent documentation.

In Liberty Hill and Georgetown (Williamson County), city-specific codes apply and can be more stringent, particularly regarding exterior material standards and energy code compliance. Georgetown enforces IECC 2021 energy standards, which require blower door testing for new residential construction — a requirement that applies equally to metal and wood frame homes. From our experience with Burnet County permitting specifically, plan approval for metal buildings with pre-engineered packages typically runs 2–4 weeks versus 4–6 weeks for custom wood frame plans.

After 7+ years building both metal and wood frame structures across the Texas Hill Country, here's the practical framework we walk clients through at TMB Construction — the same questions we ask on a free estimate call at 830-289-3852.

Choose metal building or barndominium construction if: your primary use includes a shop, storage, or agricultural function alongside living space; your budget is under $200,000 for a finished structure; you're on rural acreage without HOA restrictions; durability and low maintenance over 30+ years is a top priority; or your timeline requires occupancy within 6 months.

Choose wood frame construction if: you're building in an established neighborhood or subdivision with aesthetic requirements; resale value in a traditional market is a primary concern; your design includes complex rooflines, dormers, curved walls, or other architectural features that are difficult to achieve in standard metal building systems; or your financing is through a conventional lender who requires traditional appraisal comparables.

For many Hill Country clients — particularly those buying 10–50 acres off Highway 29 between Burnet and Georgetown, or along RR 1431 near Marble Falls — the answer is a metal barndominium with a wood-framed interior that delivers the best of both systems. We've completed over a dozen of these hybrid builds, and they consistently deliver within budget, on schedule, and with long-term performance that pure wood frame construction in this climate cannot match at the same price point.
