One Vanderbilt

 office building, under construction

www.onevanderbilt.com/

1,401-foot, 58-story Neo-modern office building completed in 2020. Designed by Kohn Pedersen Fox for S.L. Green, it takes up the full block bounded by Vanderbilt Avenue, 42nd Street, Madison Avenue, and 43rd Street. Four buildings on the block were demolished to make room for the project, the tallest of which was the 18-story Vanderbilt Avenue Building. Formally, the building’s massing comprises four interlocking and tapering volumes that spiral toward the sky. The sloping, obelisk-like walls of the tower end in a roof line at 1,301 feet, topped by a 100-foot spire. The building has extra-tall ceiling heights compared to most office towers.

One Vanderbilt's facade and design is intended to integrate with Grand Central, across the street. It is set 10 feet back from the street to allow better views of Grand Central, and the open spaces in One Vanderbilt will span up to 105 feet high. Its silvery-blue glass facade is described as having terra-cotta in the design, in the form of spandrels separating each floor. Within the spandrels there is a diagonal pattern. On the bottom few floors, the top section of the facade slopes upward, while the bottom section slopes downward, creating a "diagonal wedge" so that the lobby area on Vanderbilt Avenue (facing Grand Central) has a ceiling sloping from 50 to 110 feet from west to east. One Vanderbilt's upper floors contain an observation deck called the Summit.
