445 Grand Bay Drive # PH-1A, Key Biscayne, FL 33149

About This Home

High above the turquoise waters of Key Biscayne rises a penthouse that simply cannot be replicated. Once featured in Architectural Digest, this legendary corner residence at Grand Bay is a statement of scale, design, and presence. From sunrise over the Atlantic to glittering sunsets across Biscayne Bay and the Miami skyline, the views are cinematic in every direction, offering endless blue water, golden light, and exceptional privacy. Spanning an extraordinary 8,435 square feet under air and 2,825 square feet of terraces, totaling 11,260 square feet as per the developer’s floor plan, the residence is defined by soaring 12-foot ceilings and grand proportions throughout. A dramatic foyer leads to a spectacular Grand Room designed for both intimate living and large-scale entertaining. The formal dining room is separate and elegant, while the completely remodeled kitchen and family room provide comfort and functionality. The fully renovated private library and custom bar enhance the home’s entertaining appeal. The primary suite is serene and expansive. All the bathrooms have just been completely remodeled, offering a fresh spa-inspired experience finished to today’s highest standards. Four (4) additional en-suite bedrooms ensure comfort and privacy. The terraces offer expansive outdoor living in the sky, perfect for sunrise mornings and sunset evenings overlooking the water and skyline. This is not simply a penthouse. It is a landmark residence, rare and impossible to duplicate.
