Construction is anticipated to begin at the beginning of 2027. An exceptional opportunity to own a stunning contemporary residence overlooking the Atlantic Ocean. Situated on a 60' wide oceanfront lot, this thoughtfully designed home will offer 5 bedrooms, 4.5 bathrooms, spacious open-concept living areas, and an abundance of outdoor space to enjoy the Florida Keys lifestyle. Featuring modern coastal architecture, expansive windows, generous covered porches, and multiple balconies, the home is designed to embrace its beautiful oceanfront setting. Highlights include an open-concept design seamlessly connects the spacious kitchen, dining area, and great room. Expansive covered porches extend the living area outdoors, offering plenty of room to relax, dine, and enjoy the ocean breeze. Additional highlights include an elevator, generous garage and storage space, and a swimming pool. For those looking to create their own coastal retreat, the oceanfront lot is also available for purchase separately for $895,000 prior to the start of construction. The adjacent oceanfront lot is also available for sale, offering the rare opportunity to combine both properties for a total of 120' of Atlantic Ocean frontage!
