Manhattan's Tallest Residential Tower Tops Out

One57 held its official topping-out ceremony on Wednesday. New York by Gehry, downtown at 8 Spruce Street, has passed the torch and One57, at 1,004 feet, will be the tallest residential building New York City—at least for a little while. It will eventually be overtaken by 432 Park Avenue - which will be the tallest residential structure in the western hemisphere - with a planned height of 1430 feet.
