One Astor Plaza, also known as 1515 Broadway and formerly the W. T. Grant Building, is a 54-story office building on Times Square in the Theater District of Midtown Manhattan in New York City, New York, U.S. Designed by Der Scutt of Ely J. Kahn & Jacobs, the building was developed by Sam Minskoff and Sons. One Astor Plaza occupies a site bounded by Broadway to the east, 45th Street to the north, Shubert Alley to the west, and 44th Street to the south. The building is named after the Hotel Astor, which had occupied the site from 1904 to 1967. SL Green Realty and Allianz own One Astor Plaza, which served as the corporate headquarters of Paramount Global until 2025. The building still serves as a major office for Paramount Skydance.
The building consists of a low base that occupies most of the site, as well as a 745-foot-tall (227 m) tower section with smaller floor areas. The facade is designed in glass and stone, with large signs. The upper stories have dark glass windows, with stone mechanical shafts on all sides of the tower. The lower stories contain a public passageway and retail at ground level, as well as a lobby and Paramount Global's Studio 1515 at the second story. The building was constructed with two theaters: a Broadway house called the Minskoff Theatre on the third floor, as well as a cinema in the basement (now an event venue called Palladium Times Square).
