A refined coastal contemporary waterfront residence, this light-filled 2013 custom home is gracefully positioned within the coveted Siesta Key Baypoint neighborhood. Thoughtfully designed and meticulously maintained, the property presents a rare opportunity to enjoy the benefits of modern construction and recent capital improvements without the cost, uncertainty, or extended timelines of new development. The residence features solid concrete block construction across all levels, impact glass throughout, three zoned Trane HVAC systems, and a tankless water heater replaced in 2024. Interiors are both elegant and enduring, highlighted by engineered hickory flooring, wood plantation shutters, Hunter Douglas easy-lift window treatments, and Minka Aire ceiling fans creating a sophisticated coastal aesthetic with timeless appeal. The open-concept kitchen and family room form the centerpiece of the home, appointed with premium appliances including a Sub-Zero refrigerator, Wolf induction cooktop, Bosch and Fisher & Paykel dishwashers, and refined finishes throughout. Four generously proportioned bedroom suites each feature en-suite baths, offering comfort, privacy, and flexibility for family and guests. Outdoor living is exceptional. The deep saltwater pool is electrically heated and supported by recently updated equipment, while professionally maintained grounds and well-fed irrigation enhance the lush, resort-style setting. The waterfront experience is truly distinguished. A 30-foot AZEK dock pairs with a new seawall completed in 2023, delivering approximately 270 feet of water frontage. The existing 10,000-lb Alumavator lift is in place, with an additional lift location already plumbed and wired. This protected sailboat-water setting offers deep water, no bridges to the bay, and effortless boating access. Other highlights include 1,200 square feet of finished, air-conditioned ground-level space ideal for a gym, media room, or flex area providing valuable additional functionality not reflected in the reported living area, a three-car garage, central vacuum system, fireplace, and a comprehensive security and camera system. The exterior was just freshly repainted. 750 Siesta Key Circle represents a rare convergence of substantial waterfront infrastructure, modern mechanical systems, and timeless coastal design set within one of Siesta Key’s most sought-after neighborhoods. A truly turnkey waterfront estate, perfectly suited for the most discerning buyer.
