Oliver Building

Address: 159 N. Dearborn St. Year Built: 1907 top addition 1920 Architect: Holabird & Roche Date Designated a Chicago Landmark: May 9, 1984

Constructed as the corporate headquarters of the Oliver Typewriter Company, this building is an excellent representation of the principles of the Chicago School of architecture.

The building's internal steel frame is clearly expressed on the facade, which is further enhanced by cast-iron ornament that subtly advertises the company's name and product. The top two floors were added in 1920 by the original architects.
