Lord Rogers’s Tower 3 at 175 Greenwich Street, between Dey and Cortlandt Streets, is a flat-topped building with asymmetrical shoulders and the diagonal beams of the exoskeletal framework seem to echo the rooftop of Tower 2. The building will rise 1,155 feet, reaching the higher pinnacle at the antennas. It will have five trading floors, three retail floors, nine mechanical floors and 54 floors of offices, for a total of 71 stories.
Cortlandt Street will be kept open between Tower 3 and Tower 4. The Port Authority had originally proposed constructing a shopping arcade that would join the buildings’ bases, but city officials objected to the loss of an open corridor between the memorial and the rest of Lower Manhattan.
