About this home

Set on 3.74 private acres just minutes from Lake Travis, this architecturally striking custom home offers a rare blend of modern design, privacy, and quality construction. Zoned to Lake Travis ISD and with no HOA, the property provides both lifestyle flexibility and long-term value.
Spanning nearly 5,000 square feet, the home features light-filled living spaces with clean lines, expansive windows, and a seamless connection between indoors and out. Elevated positioning captures sweeping Hill Country skies and memorable sunsets, creating a sense of calm and retreat while remaining close to lake amenities.
Built with an emphasis on durability and efficiency, the residence features concrete exterior walls, foam insulation, and European-style windows, resulting in a solid, quiet, and energy-conscious living experience. The thoughtful layout supports both everyday comfort and effortless entertaining, with generous gathering areas balanced by serene private retreats.
A separate guest casita offers flexibility for visitors, multigenerational living, or a private office, while a four-car garage provides ample room for vehicles, storage, and recreational gear.
The expansive acreage allows for future personalization, including outdoor living spaces, a pool, additional structures, or boat and RV storage, while preserving the openness and privacy that define the property.
Located just minutes from Lake Travis and top-tier schools, this distinctive Hill Country estate offers modern architecture, quality craftsmanship, and an exceptional opportunity to own something truly special.
