Description

Newly Built Gulf-front Sanctuary with Panoramic Views, Guest and Pool Houses, Luxe Outdoor Living, and a Deepwater Navigable Dock. Set on 3 secluded acres+/- along one of the most protected stretches of the Gulf of America, 57783 Morton Street is a newly completed estate of rare scale, privacy, and modern coastal design. Surrounded by water, sandscape, and tidal ponds alive with marine life, the property offers more than 200'+/- of direct water frontage and uninterrupted views across the open Gulf. Completed in 2025 by builder and developer Alderuccio Corporation, this resilient, elevated retreat is constructed entirely of concrete and impact glass and is designed for effortless indoor-outdoor living. With three distinct finished living spaces totaling approximately 10,000 SF+/-, the estate functions as a private resort offering privacy, recreation, and exceptional access to the best of the Florida Keys. Though private and serene, the estate remains close to everything that defines Keys living. Dining, marinas, and shopping are less than ten minutes away, and the Florida Keys Marathon International Airport lies 4 miles+/- from the property for seamless private aviation access. Deepwater routes, snorkeling coves, and renowned fishing grounds are just moments from the protected 100' dock. The architecture emphasizes clarity, durability, and immersion in water and light. Walls of impact glass capture views of the Gulf, the bay, and the property's own tidal ponds, allowing natural light to animate the interiors throughout the day. Generous room proportions, ceiling heights of 10' to 12', and open circulation reinforce a sense of airiness and connection. Every finish, from porcelain flooring to quartzite counters and exterior of shell-stone, was selected for both resilience and refined coastal style. Smart home systems, solar power with battery backup, and integrated storm protection underscore a commitment to performance and longevity.
