Description

Welcome to 16 Seaside, an extraordinary oceanfront estate showcasing the perfect balance of modern design, functionality, and refined coastal living. This newly constructed residence is situated on a protected private basin offering the rare, secure deep-water dockage with a sandy peninsula. The private basin provides parking for up to six vessels, each equipped with shore power and water, making it a boater's dream. Spanning 6,585 square feet under air, the home features seven bedrooms, seven en-suite baths, and two half baths, including dual primary suites designed for multi-generational living or guest privacy. The interior exudes modern luxury with a custom chef's kitchen, climate-controlled wine cellar, multi-level elevator, four-zone AC system, and comprehensive smart-home automation managing lighting, audio, climate, pool, and security. Every detail was curated for seamless living and entertaining, from the expansive third-floor entertainment suite overlooking the ocean to the open-concept living spaces lined with glass doors and terraces capturing panoramic views. Outdoors, enjoy a resort-style pool and spa, covered summer kitchen, and a tiki hut on your private sandy beach framed by lush landscaping and privacy fencing. Seven balconies provide stunning vantage points, while an automatic entry gate and approximately 2,500 square feet of covered parking offer security and convenience. Built to last with reinforced, poured concrete construction, impact glass, and a whole-home generator, this residence combines elegance with durability. Set on a .48-acre double lot with flexible suburban/commercial zoning ideal for events and vacation rentals, 16 Seaside delivers unmatched versatility and long-term value. Located just one hour from Miami, this exceptional Key Largo waterfront estate embodies the essence of a Florida Keys lifestyle, where oceanfront serenity, modern craftsmanship, and world-class boating converge in one remarkable private estate sized property
