Why Build with Capricorn?

Building a custom home involves hundreds of decisions, and we believe those decisions should work together - not be made in isolation. We stay involved from the early planning stages through construction, helping clients think through layout, architectural details, materials, interior selections, budget, and buildability as the home takes shape.

Build On Your Lot

Many of our clients already own land or are planning to purchase property. We build on private homesites and acreage throughout the Texas Hill Country, including properties with slopes, limestone, and other terrain that requires thoughtful planning.

During the planning phase we evaluate site access, utilities, topography, drainage, permitting requirements.

Beyond custom homes, we take on select residential projects that call for the same level of thoughtful planning and craftsmanship - from guest houses and casitas to conservatories and other unique structures.

If you’re considering a new build project, we can help you evaluate your property, clarify your goals, and determine the right path forward.
