Premier Lake Travis Waterfront Estate | 3+ Acres | 400+ Ft Main Basin Shoreline

Positioned on over three private acres with more than 400 feet of shoreline along Lake Travis’ main sailing basin, this gated estate represents a rare combination of scale, usable waterfront, and long-term value—an increasingly scarce offering on the lake.

Expansive windows frame panoramic lake and Hill Country views, filling the home with natural light. Open-concept living and dining spaces extend seamlessly to covered terraces, creating a true indoor-outdoor lifestyle designed for both everyday living and elevated entertaining. Soaring ceilings, a stone fireplace, and refined finishes anchor the main living areas.

The chef’s kitchen is equipped with Thermador appliances, custom cabinetry, and a large central island, opening directly to the living spaces and outdoor areas.

Two main-level primary suites offer private retreats with lake views and spa-inspired baths. An elevator connects to a lower level featuring guest quarters with private entry, a fitness space, and a five-car garage—ideal for extended stays or multi-generational living.

The grounds offer a true Lake Travis compound experience, with mature Live Oaks, rolling lawns, resort-style pool and spa, sand volleyball court, multiple firepits, and a private boat dock with deep-water access.

Located in Travis Landing, residents also enjoy access to a 35+ acre waterfront park with private boat ramp.

A rare opportunity to own a premier waterfront estate combining privacy, scale, and lifestyle in one of Lake Travis’ most desirable settings.

At $832/sqft, this home is priced 113% above the Austin active market average of $391/sqft, reflecting premium positioning, typically tied to finishes, lot, location, or view. View Austin market report →
