Commanding breathtaking Atlantic vistas from its privileged eighth-floor setting at Grand Bay Tower, this residence is a rare offering on Key Biscayne. Enjoying an unusually private setting with unobstructed ocean views and minimal visibility from neighboring residences, the home offers a level of seclusion seldom found in oceanfront condominium living.

Spanning approximately 3,950 square feet, the living and dining areas, a cozy family room, and a bright kitchen with breakfast area are complemented by three terraces totaling approximately 595 square feet, seamlessly integrated to capture sweeping Atlantic views from every room. Custom woodwork by renowned designer Juan Montoya enriches the interiors, while the serene primary suite offers a secluded sitting room, bespoke closets, and a spa-inspired bath, creating a private sanctuary within this singular home. The sale includes one storage unit. Combining exceptional scale, refined finishes, remarkable privacy, unobstructed Atlantic views, and desirable ancillary spaces, this residence represents a unique opportunity within one of Key Biscayne’s most prestigious oceanfront buildings.
