Opened in 1913 and expanded in three stages, it was the headquarters of The New York Times newspaper until 2007. The original building by Mortimer J. Fox of Buchman & Fox, as well as a 1920s addition by Ludlow & Peabody and a 1930s addition by Albert Kahn, are on 43rd Street. Shreve, Lamb & Harmon designed a wing on 44th Street in the 1940s. Columbia Property Trust owns most of the structure as an office building while Kushner Companies owns the lowest four floors as a retail and entertainment complex.

Ludlow and Peabody was an American architectural firm with offices in New York City formed by partners Charles S. Peabody and William Orr Ludlow in 1909. The firm continued in practice under that name until 1935.
