Welcome to 21936 Briarcliff Drive — a rare, gated estate on a coveted deep-water cove of Lake Travis, designed for both grand entertaining and relaxed everyday living. The 4,352 sq ft main residence offers 4 bedrooms, 3.5 baths, and an open floor plan filled with natural light. Walls of windows frame panoramic lake views, while the refreshed chef’s kitchen—finished in Taj Mahal quartzite—flows effortlessly into the living area with fireplace and onto a dual-level patio perfect for coffee at sunrise or wine at sunset as boats glide by. The main-level primary suite is a true retreat with dual walk-in closets, spa bath, and private access to a covered patio overlooking the lake. Upstairs, a large game room with deck and three guest bedrooms provide comfort and flexibility. Over the detached four-car garage sits a 1,144 sq ft guest apartment with full kitchen, living room, bedroom, and bath—ideal for multigenerational living or long-term guests. Outdoor living shines with multiple terraces, mature landscaping, and a two-slip dock topped by a party deck with swing. With remarkably deep water, the dock remains usable year-round, even in low lake levels. An additional parcel extends from the bluff nearly to the lake’s midline, and the entire property is enclosed by wrought-iron fencing with a private gate. Offered furnished and turnkey, this home is ready for its next chapter. Neighborhood amenities include nature trails, a disc-golf course, family park, dog park, and community center. Located within Lake Travis ISD and near Briarcliff Marina and Pedernales Golf Club, this property perfectly blends privacy, prestige, and the Lake Travis lifestyle.
