Live BeachesMLS listings matching this search in Key Biscayne, Florida, updated throughout the day.

Penthouses on Key Biscayne belong to a short list of buildings, most of them on Crandon Boulevard and Ocean Drive. The Ocean Club supplies several, from the top floors of Ocean Tower One near the beach to the low rise Lake Villa buildings set around the community's lake, with ocean and bay views. Oceana Key Biscayne on Ocean Drive and the Grand Bay Residences on Grand Bay Drive count among the newer luxury addresses on the island. Each building sets its own fee, reserves and rules, even within one community, so compare what the last penthouse in the same Key Biscayne building sold for, how the roof and terraces have been maintained and what the association has set aside for both.
