Waterfront isn’t an accurate description of this $24.9 million home on Key Biscayne, Fla. The 11,500-square-foot home is practically a private peninsula basking on more than a half-acre surrounded on three sides by the azure Atlantic. Built in 1981, the 6-bed/8.5-bath home is surrounded by a manicured yard that highlights a private dock with a boat host and a swimming pool. Marble, tile and wood floors are mixed throughout the two-story house, which has unrestricted ocean views from every room and was designed for family gatherings and entertaining. [via realtor]
