About this home

Welcome to 21603 Thomas Cove, Lago Vista, Texas — where modern luxury meets limitless potential. Nestled just steps from Lake Travis, this custom 4-bedroom, 3-bath home sits on 1.74 acres of flat, cleared land, offering stunning Hill Country and Lake Travis views with rare R4 multifamily zoning for future expansion or investment. Step inside and experience the perfect blend of elegance and function — 12’ ceilings, floor-to-ceiling windows, and an open-concept layout that flows seamlessly into the covered outdoor living space with a full outdoor kitchen (BBQ, sink, refrigerator). The ideal place to relax, entertain, or add a pool to capture the Texas sunsets. Built with 2x6 energy-efficient construction and full spray-foam insulation, this home was designed for comfort and longevity. The versatile floor plan works beautifully for families, multigenerational living, or investors — with room to add a guest house, workshop, or additional duplexes/homes along the front of the property.
