About This Home
Set behind private gates along a protected stretch of open water on constant-level Lake LBJ, 507 Sandy Mountain Drive captures the rare balance of expansive lake views and calm waterfront living. Positioned just off the main body of the lake in a quiet enclave of Sunrise Beach, the property enjoys panoramic water vistas and a peaceful waterfront setting ideal for kayaking, swimming, and relaxed lakeside enjoyment. The Mediterranean-inspired Savant smart home blends timeless stone architecture, arched passageways, and limestone accents across 3,617 sq. ft. The main living area centers around a dramatic limestone fireplace and opens to a covered patio overlooking the lake, while the kitchen features granite countertops, custom cabinetry, a professional-grade range, and wine alcove. The main-level primary suite offers private patio access and a spa-like ensuite bath with a whirlpool tub and walk-in shower, while upstairs, two private guest suites each feature fireplaces and private patio access. Outdoor living unfolds beneath a canopy of mature oaks with multiple patios, an outdoor kitchen, and custom lakefront water feature. The oversized dock with Trex decking features a covered gathering space, large boat lift, and dual PWC lifts with touchless covers, delivering a refined waterfront retreat in the heart of Sunrise Beach.
