Situated on 2+ acres within gated Costa Bella, this waterfront estate offers year round Lake Travis enjoyment-an increasingly rare combination of acreage, privacy, & consistent water access. A private path to the observation deck & tram lead to a two-slip boat dock in a protected deep-water cove, navigable even during drought conditions. The dock accommodates a 23'+ boat & jet skis with HydroHoist lifts, providing immediate access to open water while shielded from heavy boat traffic. Designed to maximize panoramic lakeviews, the home features nearly 2,000 square feet of terraces and balconies with windows framing the lake from the grand foyer, dining, primary suite, library, and main living areas. The main residence includes 4 bedrooms, 4 full baths, and 2 half baths. A separate casita with private entry & kitchenette is ideal for guests, multigenerational living or poolside entertainment. Architectural details include soaring ceilings, wood beams, stone accents, & custom millwork. The refreshed gourmet kitchen features updated countertops, backsplash, redesigned island, and Janska range, opening to cozy patios for alfresco dining. The primary suite offers terrace access, fireplace, coffee bar, spa bath, and sweeping water views. Resort-style outdoor living includes a heated pool, expansive terraces, and sunset views across the cove. Recent improvements include HVAC (2024), retaining wall/foundation enhancements (2024), pool updates, Tesla solar system with three Powerwall batteries, and smart lighting integration. Residents enjoy access to the Costa Bella waterfront clubhouse with pool, fitness center, lighted tennis & basketball courts, and event space. Located in highly acclaimed Lake Travis ISD, minutes to Bee Cave, Lakeway, Hill Country Galleria, & ~30 minutes to Downtown Austin, this deep-water Lake Travis property offers gated privacy, resort amenities, and rare proximity to the city.
