1080 Mariner Dr, Key Biscayne FL 33149

At the end of a private cul-de-sac, 1080 Mariner Dr, Key Biscayne FL 33149 is a two-story waterfront home built in 2018. Set on a 12,900-square-foot lot, the residence has six bedrooms and six-and-a-half bathrooms, with sweeping water and mangrove views. A dramatic entry leads into light-filled living spaces framed by floor-to-ceiling glass.

Wide-plank European oak floors and custom millwork give the interiors a consistent, carefully finished feel. The kitchen pairs Italian cabinetry with a marble waterfall island and Miele and Sub-Zero appliances. A separate family room adds another space to gather, apart from the main living areas.

The primary suite includes a private sitting area and expansive custom closets. Its bathroom brings together book-matched marble, a freestanding soaking tub, dual vanities and a glass-enclosed rain shower. The secondary suites each have private bathrooms and bespoke finishes, giving the bedroom layout a sense of privacy throughout the home.

Covered terraces extend the living spaces outdoors, with natural stone flooring and a summer kitchen fitted with custom cabinetry and Wolf appliances. The pool is surrounded by tropical gardens curated by CCLA, creating a landscaped setting for outdoor dining and time by the water. A private dock provides direct access to Biscayne Bay, with ocean access also available.

A two-car garage and paver driveway complete the property. From the detailed interior finishes to the covered outdoor spaces, the home offers distinct areas for gathering and retreating, with the waterfront setting remaining central to its design.
