Design-build in Texas
We build our plans across San Antonio, Austin, Dallas, Fort Worth, Houston and rural Texas: site visit, permit drawings sealed by a Texas engineer where required, the slab designed from your geotechnical report, and construction by one team.
Build it with us: if Cowboy Tiny Homes builds this home for you under a contract signed within 12 months of your purchase, we credit the full plan price toward the build.
Built from this plan's own 94-line materials takeoff plus labor by trade, then adjusted for each Texas market. Pick your area and finish level.
Excludes land, utility connections, driveway, the geotechnical report and engineering. Coastal sites add windstorm upgrades. A planning estimate, not a bid.
Every plan set includes a 94-line takeoff with quantities, units and prices, ready to send to a lumberyard for a quote. The summary by category:

Accessory buildings without a kitchen are usually simpler to permit than a dwelling, and some Texas cities exempt small buildings altogether. Rules on size, height and setbacks still apply, and adding a bathroom or sleeping area can change how the city classifies it. Ask your building department first. See the Texas tiny house laws guide.
The drawing set is organized the way Texas building departments expect: a cover sheet with code, load and climate notes, plans, elevations, a section, the slab, framing, electrical and plumbing. These are planning drawings, not stamped construction documents. Many cities, lenders and insurers will ask for a Texas-licensed engineer's or architect's seal, a site plan and energy-code forms, so plan for that review before you build.

No. They are planning and permit-development drawings, not stamped documents. Texas cities that require a permit review plans under the IRC with their own amendments, and many want a Texas-licensed engineer's seal, especially on the slab and on coastal wind design. We can arrange that, or your own engineer or architect can review and stamp the set.
With an upgrade. The plans assume 115 mph inland design wind. Houston-area and coastal sites need engineered wind design, impact-rated or protected windows, and, inside the Texas Department of Insurance catastrophe area, TDI windstorm certification (WPI-8).
Yes. We can flip the layout, change room sizes, swap the slab for pier-and-beam, or add a porch. Ask for a modification quote.
Your purchase includes a license to build one home from the plan. You can print and share the drawings with your builder, lender and permit office for that build. See the terms of sale.
