Building a custom home in Texas takes 10–18 months and costs $150–$300 per square foot in the Hill Country. The 10 key stages are: financing, land selection, hiring a GC, design and permitting, site prep, foundation, framing, mechanical rough-ins, finishes, and final inspection. Burnet County conditions and Texas climate add unique timing and cost factors.
Building a custom home in the Texas Hill Country is one of the most rewarding investments you can make — and one of the most complex. Most homeowners in Burnet, Marble Falls, Lampasas, and surrounding areas start the process without a clear roadmap, and that lack of preparation costs them time, money, and serious stress. In our 7+ years building custom homes across Central Texas, the team at TMB Construction has walked hundreds of clients through every phase of this process — from raw land in Bertram to finished barndominium-style homes on the shores of Lake LBJ near Kingsland. We've permitted projects through Burnet County, Llano County, and Williamson County. We know exactly where projects stall, where budgets blow out, and where the right contractor makes all the difference. This guide gives you the complete, honest picture of what custom home building in Texas actually involves. You'll get real timelines, real cost ranges based on current Hill Country pricing, specific permit requirements, and field-tested advice from a team that does this work every day. Whether you're building on FM 963 outside Bertram or on a cedar-covered acre near Horseshoe Bay, this is the step-by-step guide you need. Have questions before you finish reading?
