1 Wall Street (also known as the Irving Trust Company Building, the Bank of New York Building, and the BNY Mellon Building) is a skyscraper in the Financial District of Lower Manhattan, New York City, on the eastern side of Broadway between Wall Street and Exchange Place. 1 Wall Street, designed in the Art Deco style, is 654 feet (199 m) tall and consists of two sections. The original 50-story building was designed by Ralph Thomas Walker of the firm Voorhees, Gmelin and Walker and constructed between 1929 and 1931, while a 36-story annex to the south was designed by successor firm Voorhees, Walker Smith Smith & Haines and built from 1963 to 1965.
The facade, made of limestone, contains slight inwardly-curved bays with fluting to resemble curtains. On the lower stories are narrow windows with mullions, as well as ornate entrances. The massing of 1 Wall Street incorporates numerous small setbacks, and the top of the original building consists of a freestanding tower. The corners of the original building consist of chamfers, while the top of the tower has fluted windowless bays. The facade of the annex is designed in a style evocative of the original structure. Inside is an ornate main lobby with colored mosaics.
1 Wall Street had been constructed for Irving Trust, one of the larger banks in New York City in the early 20th century. At the time of its construction, the building occupied what was then considered one of the most valuable plots in the city. The building replaced three previous structures, including the Manhattan Life Insurance Building, once the world's tallest building. After Irving Trust was acquired by The Bank of New York Mellon (BNY Mellon) in 1988, 1 Wall Street subsequently served as BNY Mellon's global headquarters through 2015. The building was purchased by Harry Macklowe and is undergoing a renovation from 2018 to 2021, which will convert it to a residential building with some commercial space.
The building is regarded as one of New York City's Art Deco landmarks, despite initially remaining ignored in favor of such buildings as the Empire State Building and the Chrysler Building. The New York City Landmarks Preservation Commission designated the original portion of the building as a city landmark in 2001.
