960 Mariner Dr, Key Biscayne | 2025 Waterfront House

960 Mariner Dr, Key Biscayne

Newly completed in 2025, 960 Mariner Dr, Key Biscayne offers 7,742 square feet under air on a 15,381-square-foot lot. With 106 feet of private waterfront, canal frontage and a seawall, the home puts waterfront living at the center of its design. A private dock with a ski-boat crane and direct Bay access supports time on the water.

Inside, the open-concept layout combines floor-to-ceiling glass with an easy connection to the outdoor living areas. The kitchen includes a cooking island, gas range and pantry, while a separate family room provides another place to gather. A den offers space for a home office or library, and maid or in-law quarters add flexibility to the layout. Closet cabinetry, walk-in closets, a storage room and a dedicated laundry room provide practical space throughout the home.

A private four-person elevator connects all levels, including the third-floor terrace, where 360-degree views take in the water and Miami skyline. An entrance foyer, French doors and custom mirrors add detail to the interiors. Outside, the pool and summer kitchen create a setting for meals and entertaining at home, with a built-in grill, outdoor shower and open balcony extending the outdoor amenities.

Parking includes a three-space attached carport, a driveway, guest parking and golf cart parking, along with electric vehicle charging. Energy-efficient construction incorporates doors, windows, insulation, roofing, lighting and HVAC systems. The home is offered unfurnished, leaving room to furnish the interiors to suit your own style.
