About this home
Brand-new construction on a 14,900 SF lot with 100 feet of water frontage on Cape Florida Drive, one of Key Biscayne's most coveted addresses. Over 7,000 SF under air is organized around a central living volume where glass, stone and light do the work — soaring ceilings, no wasted space, no borrowed style. The custom Ernesto Meda kitchen pairs Italian craftsmanship with fully integrated appliances and an oversized island, while a complete summer kitchen anchors the covered terrace and is built for how the island actually entertains. Smart-home integration runs lighting, climate, shades, audio, security and cameras from a single interface. Resort-style pool, expansive entertaining terrace and a private dock. Impact glass throughout. Minutes to the Village, Crandon Park, tennis and the beach.
