550 Harbor Dr, Key Biscayne | Waterfront Single-Family Home

550 Harbor Dr, Key Biscayne

At 550 Harbor Dr, Key Biscayne, this Mediterranean-style waterfront home sits on a double lot on Hurricane Harbor, overlooking Manatee Lagoon. Built in 2003, the residence offers seven bedrooms and seven full bathrooms plus a half bath, with live-in staff quarters included in the layout. Expansive living areas open to large covered porches, extending the home's gathering spaces outdoors for dining and relaxing by the water. An elevator serves the home, while an open balcony provides another outdoor setting. The layout brings together generous shared spaces and separate accommodations for staff or extended family.

The 13,302-square-foot property has a pool and a professionally landscaped yard with room for outdoor entertaining. Its waterfront setting includes frontage on a canal at least 121 feet wide, with ocean access and no fixed bridges—an important consideration for buyers who want a home connected to the water. A four-car garage offers substantial enclosed parking, complemented by a paver driveway, golf cart parking and additional parking spaces. The combination of covered outdoor living areas, landscaped grounds and direct water access gives this home a distinctly waterfront focus, with space to spend time both inside and out.
