Beyond the gates lies an oceanfront estate whose finest qualities extend far beyond what you have seen! From its protected private marina offering 6 boat slips and fully integrated smart-home technology to its rooftop observation deck, private sandy shoreline, and resort-caliber outdoor living, every element has been designed to deliver an exceptional waterfront lifestyle. Welcome to 16 Seaside Avenue. From the moment the private gates open, a fully integrated smart home system seamlessly controls the estate--from the front entrance and security system to interior lighting, climate, surround sound, and even the dock lighting--creating a level of convenience rarely found in waterfront homes. A commercial elevator services all three levels, while a whole-house generator provides peace of mind year-round. With everyday living in mind, the home features 2 dedicated laundry rooms for the upmost functionality. Every bedroom serves as a private retreat, complete with its own spa-inspired ensuite bathroom, spacious walk-in closet, and custom built-in closet system. Expansive open living areas are filled with natural light and thoughtfully designed to maximize breathtaking Atlantic Ocean views. Outdoor living rivals that of a private resort. The spectacular oceanfront pool, spa and waterfall, covered gazebo, outdoor kitchen, and integrated indoor and outdoor surround sound create the perfect setting for entertaining. A private sandy beach and pier provide an idyllic place to enjoy spectacular sunrises over the Atlantic, while the rooftop observation deck captures sweeping panoramic ocean views of both the ocean and bay. Best of all this property offers the ability for short term 7-Day rentals! This is a rare opportunity to own an estate designed to deliver the very best of the Florida Keys!
