In 1855, the Corn Exchange Bank moved into an existing building in New York City at the northwest corner of William and Beaver Streets in Manhattan.

[1] In 1894, the bank completed its new headquarters, an 11-story building designed by Robert Henderson Robertson located at 11-15 William Street.

After Chemical Corn merged with New York Trust Company in 1959, the words "Corn Exchange" were dropped, creating the Chemical Bank New York Trust Company.

[2] As late as 1928, photographs show that the Corn Exchange Bank had a branch in a building on Grove Street, approximately 50 feet east of Seventh Avenue South in Greenwich Village.

The enlarged building's exterior appearance is virtually unchanged since 1954, likely due to the creation of the New York City Landmarks Preservation Commission in 1965 in response to the mounting losses of historically significant buildings in New York City, most notably the old Pennsylvania Station.
