Why Koti picked this home
This luxurious Santa Barbara-style home boasts a private boat dock, stunning lake views, and multiple living areas.
Set behind dual gated entries along one of the most coveted stretches of Lake Austin, Butterfly Beach is a Santa Barbara inspired estate offering exceptional privacy, scale, and craftsmanship. Positioned on nearly three acres with over 250 feet of waterfront, the property features a grand, level arrival, tranquil pond, and a courtyard framed by gardens and flowering vines. The residence spans more than 7,500 square feet, designed to live in harmony with its surroundings, with nearly every room opening to the landscape and lake beyond. Interiors are defined by hand troweled Venetian plaster walls, custom ironwork, bespoke lighting, and a refined material palette throughout. A dedicated wine room and a flexible theater room, which can serve as a bedroom or exercise studio, add versatility. At the center of the home, the chef’s kitchen features custom cabinetry, marble and granite surfaces, and a Lacanche French range. Supporting spaces include a butler’s pantry, additional refrigeration, and generous storage. A central reverse osmosis system services five locations, including the kitchen, butler’s pantry, coffee bar, wet bar, and outdoor kitchen. Outdoor living offers expansive terraces, a negative edge pool, and a private two slip boat dock with upper entertaining deck and automated screens. Surrounded by nearly eight acres of protected wildlife preserve, the property provides a rare sense of privacy. A separate guest casita with private access includes a bedroom, full bath, and flexible living space. Additional features include a five car garage configuration with climate controlled workshop, glass show garage, and a fire suppression system. Rare opportunity to own a premier Lake Austin estate.
