Designed by Sloan & Robertson in the Art Deco style, with the assistance of Chanin's own architect Jacques Delamarre,The Chanin Building was constructed in 1927–1929, and was almost fully rented upon opening. Over the years, the upper floors have contained a movie theater, observation deck, and radio broadcast station, while the lower floors were used as offices and a bus terminal. The building was designated a New York City landmark in 1978, and was added to the National Register of Historic Places in 1980.
