The Oliver Building is located at 159 N. Dearborn Street in Chicago within the Loop. It was built for the Oliver Typewriter Company from 1907-1908 by Holabird & Roche. When two floors were added in 1920, Holabird & Roche were hired for the expansion. The cast iron exterior features typewriter-related motifs. It was declared a Chicago Landmark on May 9, 1984. The windows above the second floor are known as "Chicago windows," and are wide window panes bracketed by narrower double-hung windows. The windows also include the name of the company below the central pane.
