Grand Bay Residences is a 13-story bayfront condominium completed in 1996 at 445 Grand Bay Drive on Key Biscayne, a GB/JT Hotel Partners development with architecture by Cohen, Friedman and Encinosa. The building carries 138 residences in a layout that runs from two-bedroom plans up through five-bedroom penthouses, and it sits adjacent to the Grand Bay community of bayfront condominiums and the Ritz-Carlton Key Biscayne. The mid-1990s build positioned Grand Bay Residences as one of the earliest contemporary luxury towers on Key Biscayne, predating the island's later cycle of Arquitectonica-designed projects by nearly two decades. The 445 Grand Bay Drive address sits inside the Village of Key Biscayne off Crandon Boulevard, the island's spine, with the Ritz-Carlton, the Crandon Park Beach, and the Crandon Park Tennis Center within a short drive. Bill Baggs Cape Florida State Park, the historic Cape Florida Lighthouse, and the island's bayside community of single-family homes sit at the southern end of the island, while Hobie Beach and the Miami Marine Stadium meet the causeway entrance to the north. Downtown Miami and the Brickell financial district are 15 minutes by car via the Rickenbacker Causeway, and Coconut Grove is reachable in 10 minutes from the bridge ramp. Grand Bay Residences faces Biscayne Bay rather than the Atlantic, so units carry city-skyline and bay views rather than ocean exposure. Residences at Grand Bay Residences run two-bedroom through five-bedroom penthouse layouts with marble baths, gourmet kitchens, balconies oriented toward Biscayne Bay, and full-floor or half-floor configurations on the upper levels. The amenity program centers on a bayfront pool deck, a fitness center, tennis courts shared with the Grand Bay community, a sauna and steam room, a residents' lounge, and 24-hour security with valet and concierge. The Grand Bay Residences Key Biscayne position pairs the island's village ordinances and limited inventory with a bayfront orientation, putting Brickell and Downtown skylines in direct view across the water.
