bathroomsSet 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.
Morton Street occupies one of Marathon’s most discreet waterfront corridors, known for its tranquility and exceptional boating. The estate sits at the end of a 500’+/- private drive, surrounded by native landscape, curated dunes, and the sound of open water meeting the shore. Natural tidal ponds stocked with fish and lobster animate the property’s ecology, while the elevated building platform delivers storm protection and uninterrupted views from nearly every room.
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.
A long private drive winds through tropical landscape before opening to a modern waterfront compound featuring the main residence with its integrated pool cabana and a separate three-level guest house nestled within the trees. Each structure is oriented for Gulf views and privacy, establishing a calm, contemporary environment along the shoreline.
The main residence is wrapped in a continuous glass façade, opening every major room to sweeping Gulf views. At its center, the great room presents a bright, open layout for living, dining, and cooking, anchored by an elegant eat-in kitchen with a waterfall-edge island and a sculptural wood-slatted ceiling feature.
The primary suite occupies its own dedicated wing, offering a quiet sense of separation and direct access to a secluded terrace. Floor-to-ceiling glass frames uninterrupted Gulf views, and a discreet drop-down television retracts from the ceiling to provide entertainment without interrupting the panorama.
Connected yet independent, the attached pool cabana offers approximately 2,000 SF+/- of sun-filled living space with an open layout framed by floor-to-ceiling glass. The living and dining areas overlook the pool, terraces, and outdoor entertainment spaces, creating an easy flow between interior comfort and the surrounding landscape.
The tree house functions as a standalone residence with approximately 3,000 SF+/- across three levels. Elevated among the palms, it offers sweeping views and complete privacy for guests or extended family.
Outdoor living centers around a heated saline pool with a wide sun shelf and an attached spa, all oriented toward panoramic Gulf views. Terraces wrap the water’s edge, while a covered entertainment patio serves as the primary gathering hub with a fully equipped outdoor kitchen and generous dining and lounge areas. A dramatic waterfront bar with seating for fourteen overlooks the pool, gardens, and water beyond.
Beyond the pool terrace, a sculpted sandscape with native plantings, rockwork, and mature trees creates a relaxed coastal retreat. Pathways weave through the soft terrain, offering quiet places to lounge with uninterrupted Gulf views.
At the edge of the sandscape, a 100’ private dock extends into clear Gulf waters, offering exceptional marine access. The private dock features two high-capacity boat lifts, able to support vessels up to 27,000 and 20,000 pounds, making it ideal for serious boating and day trips throughout the Keys.
