Welcome to Serenity Shores - one of the most flexible and compelling opportunities currently available on Lake Austin. Set across 1.91 private acres with dedicated lake access, this property offers what is increasingly difficult to find: usable waterfront amenities, existing livable improvements, and fully approved plans to expand into a landmark estate. A modern 4-bedroom, 2,400-square-foot residence with pool is already in place, allowing immediate enjoyment of the property. A private gazebo at the water's edge, shared dock easement, and boat slip create effortless access to Lake Austin - the lifestyle buyers come here for. What sets Serenity Shores apart is its future potential. Permitted plans are approved for a 4,000-square-foot main residence atop the ridge, complete with a tennis court, pool, and three-car garage. The septic system is already sized for a five-bedroom estate, enabling a true compound without the uncertainty of entitlement risk. The existing home reflects a warm organic-modern aesthetic, designed to maximize views and indoor-outdoor living. The upper level opens to an expansive entertaining terrace with built-in grilling and bar seating, while the lower level connects directly to the pool and landscaped grounds, surrounded by privacy and canyon vistas. Minutes from central Austin and zoned to Highland Park Elementary, Lamar Middle, and McCallum High School, the property balances seclusion with convenience - a rare combination in the Lake Austin corridor. Serenity Shores is not simply a home. It is a strategic Lake Austin acquisition: livable today, expandable tomorrow, and positioned to become a multi-generational estate.
