Property Description

Dominating the Key Biscayne skyline, this Geoffrey Bradfield–designed penthouse is a rare display of power, prestige, and absolute luxury. Encompassing 13,630 sq. ft. with 10,421 sq. ft. under air and 3,000+ sq. ft. of oceanfront terraces, it commands 100 feet of unobstructed beachfront with sweeping sunrise and sunset views. Directly adjacent, the $100M+ newly reimagined Ritz-Carlton and its brand-new Beach Club sit at your footsteps, elevating exclusivity to a world-class level. Inside, soaring ceilings showcase a showpiece chef’s kitchen, grand dining, four-private en-suites, a refined executive office, staff quarters, and couture-caliber closets. Includes five premium parking spaces and five oversized private storage cages. A true trophy residence at the apex of coastal luxury.
