Craftsmanship and one accountable local team on every custom home
Iron C Construction is a Wimberley-based custom home builder in the Texas Hill Country, building high-end custom homes and managing every stage of construction for clients across Greater Austin and Central Texas. Founded in 2020 by Robert Castro, Iron C Construction grew from careful remodeling work into full residential and commercial construction, and that history shows in how we build custom homes today. We treat each home as a long relationship, not a transaction, and we keep one accountable local team on your project from the first design conversation to the final walkthrough.
We work across Hays, Travis, Williamson, Bastrop, Caldwell, Comal, Blanco, Burnet, and Kendall counties, building for custom-home buyers, families upgrading the home they already love, and owners developing raw land across the area. Whatever the starting point, the goal is the same: honest pricing, clear communication, and craftsmanship you can stand behind for decades.
Choosing the right custom home builder matters more than choosing a floor plan. A great builder protects your budget, your timeline, and your peace of mind, and a poor one can turn the project of a lifetime into a year of stress. Iron C Construction earns that trust by staying involved at every step, answering hard questions directly, and building homes we are proud to put our name on.
What we build
Our custom-home capability covers far more than a single floor plan. Iron C Construction designs and builds new homes from the ground up, and we also handle the additions, remodels, and accessory structures that turn an existing property into the home a family actually wants. Explore each of our custom-home services below:
- Home additions add square footage, new rooms, second stories, and reconfigured living space without forcing you to move, and we tie the new work cleanly into the original structure.
- Whole-home remodels and renovations rebuild a dated or worn property into a modern, efficient home, from layout changes and structural updates to finishes throughout.
- When you already own the land, we build on your lot, managing site evaluation, design, and construction so your home fits the parcel and the terrain you chose.
- Custom barndominiums are a signature Hill Country product for us, combining durable metal-and-frame construction with comfortable, finished living space on acreage.
- Garages, shops, and accessory structures give you the workspace, storage, and equipment cover that a working rural property needs.
- Guest houses and casitas create a separate, finished living space for family, guests, or rental income, built to match the main home.
If your project leans toward business space rather than a residence, our commercial construction team handles ground-up and large-scale commercial builds with the same local accountability.
What to expect from our custom home builder in the Texas Hill Country
A custom home is a big commitment, so we keep the process structured and transparent from day one. Every project moves through four clear stages, and you always know who to call and where things stand.
- Design. We start with how you live, then translate it into a buildable plan. Our in-house drawings and 3D renderings let you see the home before a single footing is poured, and we adjust early when changes are cheap rather than late when they are expensive.
- Pre-construction. Before we break ground, we finalize budgets, schedules, permits, and site logistics. Our pre-construction services, including construction drawings and plans, 3D renderings, and site layout and staking, set the foundation for a build that runs on schedule and on budget.
- Build. Construction Coordinator Arthur Leyva, who brings more than 20 years in the trade, keeps the crews, schedule, and quality on track. We build to the plan, document progress, and flag anything that needs a decision before it becomes a problem.
- Walkthrough. Before we hand over the keys, we walk the finished home with you, confirm every detail meets the standard we promised, and address punch-list items the right way.
Because we self-perform and coordinate as one team, the same people who plan your home are accountable for delivering it.
Building on Hill Country land
Building in the Central Texas Hill Country is not the same as building on a flat suburban lot. Limestone, slope, tree cover, well and septic considerations, long driveways, and county-specific requirements all shape what a home costs and how it sits on the land. Iron C Construction has built across this terrain, so we evaluate a parcel honestly before you commit, rather than promising a number that does not survive contact with the rock underneath.
If you already own acreage near Wimberley, Dripping Springs, Driftwood, Blanco, Johnson City, or anywhere across the counties we serve, we can build on your lot and design a home that works with the views, drainage, and access you have. If you are still shopping for land, we are glad to walk a property with you and share what a custom home there would realistically involve. Site work like layout and staking happens up front, so the home lands exactly where it should.
That same local knowledge guides how we orient a home for shade and prevailing breezes, how we plan drainage so heavy rain moves away from the foundation, and how we sequence the build around access challenges on remote lots. These are the details that separate a home that simply gets built from one that performs well for years, and they are far easier to get right when your builder has worked this land before.
Why homeowners choose Iron C Construction
Clients hire Iron C Construction because we do things the right way, even when it is slower or harder. Transparency is built into how we price, schedule, and communicate, so you are never guessing where your money went or when the next phase starts.
- One accountable local team. Robert Castro, Arthur Leyva, and Michaela Hernandez run a tight operation, and you work with the same people the whole way through.
- Honest pricing and clear scope. We quote the real cost of doing the work correctly and explain the tradeoffs, rather than winning the job with a low number and making it up in change orders.
- Genuine craftsmanship. High-end custom homes demand attention to detail, and our reputation depends on the quality we leave behind on every project.
- Local knowledge. We know this area, its land, its inspectors, and its trades, which keeps your project moving instead of stalling on surprises.
