448 Harbor Dr

Teak screens filter the low island sun across this 2021 residence on Harbor Drive, a short walk from the beach and the village center of Key Biscayne. The house offers 4,190 square feet of interior space on a 13,000-square-foot lot (0.3 acre), with six bedrooms, six full baths and one half bath. White stucco volumes and full-height glass sliders face a 50-foot lap pool that runs the length of the garden, with impact glass throughout.

Warm white oak and honed travertine carry through an open main level of living room, dining area and kitchen, where a travertine island overlooks the pool. With the sliders open, the covered terrace and pool deck become part of the room, and a guest suite completes the ground floor. Upstairs, the primary suite looks over the garden through its own teak screen, with a travertine bath and a walk-in closet; each remaining bedroom has its own bath.

A stair continues to the rooftop terrace, a teak-decked platform above the palm canopy turned west toward the sunset. Royal and coconut palms, sea grape and silver buttonwood give the garden depth and privacy, and a two-car garage keeps the street side clean. The villa is offered for sale with beach paths, cafes and the island’s parks within walking or cycling distance.
