The private boat dock and lift at 4407 Island Cove puts Lake Austin directly at your fingertips, a rare luxury that transforms waterfront living from concept to daily reality. Situated within the gated Austin community in Austin's 78731 zip code, this 8,286-square-foot residence sits on its own cul-de-sac with 0.527 acres of landscaped grounds that screen you from neighbors while opening entirely toward water views and the constant, meditative presence of the lake itself.
The 2006-built masonry home was comprehensively remodeled and now functions as a personal sanctuary designed for both privacy and entertaining. Two primary bedroom suites provide flexibility for multi-generational living or guests who need true privacy. A separate casita with its own bath offers a guest wing that feels genuinely independent. The main residence includes a chef's kitchen with dual islands, convection and double ovens, and sightlines directly to the pool deck and water beyond. A game room with sunken bar overlooks the canal. The master suite and multiple living areas are positioned to capture water views from multiple angles. Stone and wood flooring throughout anchor the interior to natural materials that complement the outdoor setting.
Outside, a heated pool, spa, and outdoor kitchen occupy the carefully terraced backyard. Medium and small mature trees provide canopy coverage while preserving lake sightlines. The private boat dock and lift eliminate the need for off-site moorage. A 4-car garage and secondary 2-car structure manage the vehicles and water toys. Home automation, a wine cellar, elevator, and gym address the practical requirements of 8,286 square feet of living.
The location delivers genuine geographic isolation despite proximity to Austin's urban center. Andrews Elementary, Lamar Middle, and McCallum High serve the property through Austin ISD, all within reasonable distance of Mount Bonnell Shores. The neighborhood itself maintains strict architectural and density standards that preserve the sense of retreat. At $959 per square foot, the asking price of $7.95 million reflects both the waterfront position and the comprehensive renovation scope.
This is ownership of actual water access in an increasingly landlocked city. The dock and lift aren't amenities listed on a pamphlet. They function daily, transforming the property from a house with a view into a lakefront lifestyle that most Austin residents can only imagine.
