See Inside the World’s Skinniest Skyscraper

Kelly Behun could not help but think of music. The ELLE DECOR A-List designer was given the opportunity to design an apartment at New York’s 111 West 57th Street and found herself drawn to the history of the site’s original occupant, Steinway Hall, a concert space intended to showcase the sound of the piano-maker’s instruments. Today, the Manhattan address is topped by a new 1,428-foot-tall tower designed by SHoP Architects—the second tallest residential building in the Western Hemisphere. With a sense of the building’s history, Behun created the interiors for a 4,500-square-foot, three-bedroom, three-and-a-half-bathroom apartment known as 34 Tower Residence on the 34th floor.
