About Grand Bay Key Biscayne
Grand Bay Key Biscayne is three oceanfront condos on Grand Bay Drive, among them the Ritz-Carlton Key Biscayne suites. Grand Bay Residences came first in 1996 and Grand Bay Tower in 1999, and the Ritz-Carlton followed in 2001 on a 17-acre site with about 600 feet of beach. GB/JT Hotel Partners developed the buildings, and Cohen Freedman Encinosa drew them. The resort's 20,000-square-foot spa and tennis center of ten clay courts are part of the setting, and Gencom is carrying out a renovation of more than $100 million with Hart Howerton.
