Custom home construction in Woodcreek
Iron C Construction is a custom home builder in Woodcreek, TX, building new homes, additions, and casitas in the small Hays County city just north of Wimberley on Ranch Road 12. Our company was founded in Wimberley in 2020 by Robert Castro, so Woodcreek is about as close to home as a project gets for our team, and the builder you meet on the first visit is the one who runs the job.
Woodcreek is a different kind of Texas Hill Country build from the ranch acreage around it. The city incorporated in 1984 and covers roughly 696 acres, including the original 18-hole Woodcreek golf course and the homes of what began as the Woodcreek Resort Subdivision. Lots here sit inside a city with its own permits, its own tree rules, and a cap on how much of a lot can be covered. Knowing those rules before design is what keeps a Woodcreek build on schedule.
City permits and plan review
Inside city limits, the City of Woodcreek requires a permit for a new home, an addition or structural remodel, and an accessory building such as a garage or guest house. Plans are reviewed against the currently adopted International codes, and the new home checklist asks for more than many owners expect:
- A foundation plan designed by a registered professional engineer.
- An energy compliance report, plus Manual J, S, and D heating and cooling calculations.
- A site plan showing setbacks and easements.
- A floodplain report and an elevation certificate when the lot sits in a mapped flood hazard area.
For accessory structures, zoning has to be approved before the code review begins. Once building starts, inspections run in a set order, from temporary power and plumbing rough-in through a slab pre-pour inspection by the design engineer, framing, insulation, and the final inspection for a certificate of occupancy. Iron C Construction coordinates the engineer, the drawings, and each inspection; we do not provide stamped engineering ourselves.
One detail catches people out. The Wimberley Springs and Woodcreek North neighborhoods sit outside the city limits, so a lot there follows the Hays County process instead, including a county septic permit for every system regardless of lot size. We confirm which jurisdiction your lot falls under on the first visit.
Trees, impervious cover, and dark skies
Three local rules shape the design of almost every home in the city.
- Impervious cover. The city’s Water Quality Protection Ordinance limits impervious cover to 30 percent of a lot. The house, driveway, patios, and outbuildings all count, so a large footprint or a long paved drive can run into the cap. We work it out on the site plan before the floor plan is final.
- Trees. The city requires a permit for all tree trimming and removal, trimming oaks is prohibited from February 1 through June 30, and work on protected oaks needs a certified arborist. Siting a house among the oaks takes planning and timing.
- Night sky. Woodcreek and Wimberley together form the Wimberley Valley International Dark Sky Community, designated in 2018. We plan exterior lighting with that in mind.
Lots under the Woodcreek Property Owners Association have one more review: the association notes that its Architectural Control Committee may need to approve new homes, additions, decks, and fences. We build that review into the schedule.
Water, wastewater, and Cypress Creek
Unlike the ranch land around it, the city is served by a utility. Aqua Texas is the franchised water and wastewater provider for City of Woodcreek residents, so most in-city lots connect to service rather than drilling a well. On nearby land outside the city, the Hays Trinity Groundwater Conservation District requires household wells to be registered before drilling.
Cypress Creek runs through the area, fed in part by Jacob’s Well, an artesian spring that keeps the creek flowing, before it joins the Blanco River in Wimberley. Lots near the creek can sit in a mapped flood hazard area, which changes where the house goes and how high it sits, and the city’s floodplain administrator reviews those projects. We check the flood maps at the start.
Remodel, add on, or build new
Development here began in the 1970s, so many lots already hold a house. Owners often weigh whether to update it, add space, or start over. That decision depends on the foundation, the layout, and how much of the 30 percent impervious cover the existing house already uses. Our guide to remodeling versus rebuilding an older home walks through how we help clients make that call.
If you are thinking about a casita for rental income, check the zoning first: the city limits short-term rentals of residential property to the SF-4 zone.
What a custom home costs to build
A useful benchmark comes from the National Association of Home Builders: the median contractor-built custom home in the United States cost about $166 per square foot to build in 2024, not counting land. It is a national starting point, not a quote.
In the city, site costs look different from rural acreage. You may skip the well and the septic field, but an engineered foundation on Hill Country limestone, tree work timed around the oak season, demolition of an existing house, and finishes all move the number. We price from your actual lot and plan, line by line, so the budget you plan around is the one you build to.
Homes and projects we build
Iron C Construction handles the full range of residential work with the same local team:
- New custom homes, from the first design conversation through the final walkthrough.
- Build on your lot for owners who already hold a homesite.
- Home additions that add bedrooms or living space to an existing house.
- Whole-home remodels and renovations for older homes.
- Custom barndominiums with a steel or post-frame shell and a finished interior.
- Garages, shops, and accessory structures for vehicles, hobbies, and storage.
- Guest houses and casitas for family, guests, or a home office.
Robert Castro stays involved in the projects we take on, and Arthur Leyva, our Construction Coordinator, brings more than 20 years of field experience to running the daily work. When something unexpected turns up, we show you what we found, explain the options and the cost, and let you decide before work moves on.
