MAKE NO SMALL PLANS. Amtrak now seeks rental income from Chicago Union Station.

As originally conceived and designed, Chicago Union Station was to be a high-rise structure, but was never completed. The station was initially designed by famed Chicago architect Daniel Burnham and completed by Graham, Anderson, Probst and White, the successor to D.H. Burnham & Co. after Burnham’s death. The building is an historically significant element of Chicago’s transportation heritage and the project would restore, refurbish and enliven a building envisioned by Burnham.

The plan by Jones Lang LaSalle and its partner calls for the preservation of the exterior elevations, rooflines and Great Hall - including the 300-foot-long barrel-vaulted skylight that soars 115 feet over the room - and adds an 18-story tower in a project totaling approximately $250 million.
