It will be 1,556 feet (474 m) tall.^[6] If completed as planned, it will become the fifteenth tallest building in the world^[7] and the tallest in New York City by roof height,^[6] surpassing the nearby Central Park Tower by about 6 ft (2 meters).

In April 2025, Macklowe sold part of the proposed Tower Fifth site at 12 East 52nd Street for $15 million.^[8][9]

Facade

The facade of Tower Fifth is designed by Gensler and would feature a closed cavity system that reduces solar heat gain by 70 percent. The massing of the structure is consistent for the bulk of the rise until it reaches a cantilevering observation deck consisting of multiple floors at the top.^[1]
