Old Chicago Post Office

Chicago’s prominence in the mail-order catalog industry led to the creation of the world’s largest post office in the city in the 1930s, when the old main post office was completed. The Post Office, as it’s called now, fronts the Chicago River and straddles Congress Parkway.

With contiguous floors of up to 250,000 square feet, The Post Office has the largest floor plates in the city, with modern offices, restaurants, shops, entertainment and park space on a roof that is the size of four football fields Designed by the Chicago offices of Gensler, CD+M provided both interior and exterior lighting design for this massive historic re-development project.
