Description for 398 Harbor Dr, Key Biscayne, FL 33149

For Sale> Miami-Dade County> Key Biscayne> 33149

Truly a trophy property ready to be developed.The original cottage on this unique 20,933 sq. ft. lot, is nestled among some of the most coveted stately homes of Key Biscayne. It may be lived in while your new house project is ready. Watch the endless parade of boats as they cruise the shimmering waters of Biscayne Bay, or simply enjoy the spectacle of the always changing color palette of Miami Sunsets and night lights. Watch an assortment of marine life stop by to greet you while you lounge in your bayfront backyard.The Key is a short ride away -10 to 15 minutes – from the excitement of Downtown Miami and the Beaches, as well as a 20 minutes ride to Miami International Airport and Miami Executive private airport, yet the Key feels so far away.
