About This Home

430 Grand Bay Dr #801

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. Originally a three-bedroom, five-and-a-half-bath home, it has been masterfully reimagined into a grand two-bedroom, three-and-a-half-bath layout, enhancing scale and flow for refined entertaining and effortless daily 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 a private guest quarters—an increasingly rare and coveted amenity at Grand Bay—as well as two storage units. 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.
