About This Home

481 21st Avenue S

Views, Views, Views! An unparalleled expression of coastal grandeur, this extraordinary waterfront estate showcases luxury living in the heart of Aqualane Shores, one of Old Naples prestigious neighborhoods, just minutes to the Gulf of Mexico, a short distance to the beach and downtown's historic Third Avenue South. Positioned along one of the community's widest canals, this architectural masterpiece captures the essence of Old Naples elite lifestyle, where timeless design, masterful craftsmanship and effortless elegance converge. A boater's and car collector's dream, the 6,130-square-foot residence seamlessly blends old Florida charm with refined sophistication, highlighted by exquisite millwork, rich hardwood flooring, shiplap accents and tranquil water views throughout the home. Designed for grand entertaining and intimate gatherings, the open-concept layout features a dramatic two-story great room, a gourmet kitchen with dual islands, and a spacious family room flowing naturally to a covered lanai with outdoor kitchen, pizza oven and fireplace. The primary suite, on the main level, affords the utmost privacy and elegance, featuring dual dressing areas and an adjoining study that easily transitions into an additional guest suite when desired. A separate guest residence, reached by private elevator, offers a full kitchen and living area, ideal for extended stays or hosting with complete independence. Among the home's many refined appointments are a temperature-controlled 500-plus bottle wine room, a stylish wet bar, a secure safe room and an impressive 12-car garage designed for the connoisseur of fine automobiles. Outside, the resort-inspired grounds unfold with a waterfront vanishing-edge pool, spa, putting green and a private boat slip with a 34,000-pound lift offering seamless, bridge-free navigation from your backyard to the open Gulf of Mexico, where turquoise waters and endless horizons await, completing this extraordinary tropical retreat.
