Experience the pinnacle of waterfront luxury on Siesta Key's prestigious Grand Canal. This meticulously reimagined residence at four thousand nine hundred thirty-eight Commonwealth Drive offers a rare blend of modern sophistication, structural integrity, and complete peace of mind. Extensively transformed both structurally and aesthetically, the home welcomes you into an expansive open-concept design filled with natural light. The newly expanded kitchen serves as the heart of the home, offering abundant cabinetry and storage, a double oven, generous pantry storage, striking custom beam detail, an open breakfast bar, and direct access to the wraparound decking—creating seamless indoor-outdoor living and effortless entertaining. A stylish powder room has also been thoughtfully added. New hurricane-impact windows and sliding glass doors frame the interiors, while designer flooring flows beautifully throughout both levels. Major system upgrades elevate the home's value and efficiency, including a brand-new roof and a comprehensive solar power system with battery storage. A fresh, contemporary interior palette enhances the clean architectural lines and airy coastal feel. The lower level adds over one thousand three hundred square feet of legal non-conforming living space with its own private entry, garage access, and elevator connection to the main living areas leading directly to the pool deck. Redesigned for modern functionality, this space features a spacious family entertainment area, custom bar, and an additional guest suite with a walk-in closet and full bathroom—ideal for extended family, guests, or a private retreat. Outdoor living is equally impressive. The private backyard sanctuary showcases a heated pool and spa with a new heater and filtration system, sleek updated decking, professional landscaping, and premium artificial turf for effortless maintenance. For the boating enthusiast, the deep-water dock and boat lift provide direct access to the Intracoastal Waterway and open waters of Sarasota Bay delivering the ultimate waterfront lifestyle.
