Capricorn Concepts is a family-owned custom home builder based in Spring Branch, serving clients throughout San Antonio and the surrounding Hill Country. We’re a husband-and-wife team, Luke and Mary Claire Patton, and we live and raise our family in the same community we serve.

Luke Patton, Principal Builder, is a U.S. Army veteran and licensed residential contractor with more than 20 years of hands-on construction experience across multiple trades, including framing, concrete, roofing, electrical, plumbing, and structural systems.

A Spring Branch native, Luke combines extensive field experience with formal architectural training. He holds an Associate of Arts in Architecture from San Antonio College and a Bachelor of Science in Architecture from the University of Texas at San Antonio. This architectural background allows him to approach each custom home with both a builder’s practicality and a strong understanding of architectural intent - helping projects move smoothly from plans to fully realized homes.

Mary Claire Patton oversees client communication, project coordination, and the overall client experience. She holds a Bachelor of Arts in Communication from the University of Texas at San Antonio and spent eight years as a journalist before joining Capricorn Concepts. She is also currently pursuing a Master’s degree in Horticulture from Texas Tech University, bringing an additional layer of insight into land, landscape, and long-term property planning.

We started Capricorn Concepts with a simple belief: homeowners deserve a better experience when building a custom home.

Too often, the process feels disconnected - decisions get rushed, details are overlooked, and communication falls off once construction begins. Our approach is different.

As a small, hands-on builder, we stay closely involved in every project and work directly with our clients from initial planning through construction and beyond move-in. The goal is consistent communication, thoughtful execution, and a level of accountability that’s hard to find with larger builders.

Building a home is a major investment, but it’s also deeply personal. The best projects happen when homeowners are part of the process - asking questions, exploring ideas, and seeing their vision take shape.

For us, success isn’t just finishing a project. It’s creating something well-designed, well-built, and lasting - a home our clients feel proud to have been part of creating.
