Waterfront condos on Key Biscayne are mostly beach buildings, and choosing among them is less about the water than about the association. The South and West buildings of the Commodore Club, the Towers of Key Biscayne and Casa del Mar share the Atlantic side with the Key Colony and Ocean Club communities, and Grand Bay Tower rounds out the page. Views change within a single community: Key Colony units look over the ocean, the gardens or the Miami skyline across the bay, and the Ocean Club sets its towers and villas around a lake. Private slips are rarely part of these listings, so a Key Biscayne condo owner who wants a boat nearby usually looks at a marina, such as the one in Crandon Park, or at a canal house instead.
