400 Madison Avenue is a 22-story office building in Midtown Manhattan in New York City. It is along Madison Avenue's western sidewalk between 47th and 48th Streets, near Grand Central Terminal. 400 Madison Avenue was designed by H. Craig Severance with Neo-Gothic architectural detailing. The building was constructed from 1927 to 1928 by the George A. Fuller Company. Despite being relatively narrow, the building attracted businessmen who sought small, imposing offices. The New York City Landmarks Preservation Commission designated 400 Madison Avenue as an official landmark in 2016.
