Roosevelt Road, and Michigan Avenue. Many of Columbia's buildings were built in the early 20th century and were acquired by the school as it expanded.

Alexandroff Campus Center Located at 600 S. Michigan Avenue, Columbia College's Main Building was built in 1906–07 by Christian A. Eckstorm, an architect popular for his industrial and warehouse designs, to serve as the headquarters of the International Harvester Company. 600 S. Michigan was a modern skyscraper of its era, built with a steel skeleton, high-speed elevators, electric light, the most advanced mechanical systems available and a floor plan designed to maximize natural light for all of its interior office spaces. The 15-story brick-clad building with classical stone detailing has an Art Deco lobby that retains much of its original marble. In 1937 the building was purchased by the Fairbanks-Morse Company, makers of railroad locomotives, farm equipment and hydraulic systems. It was acquired by Columbia College in 1975. In its early years as the home of Columbia, it was adaptively reused to house classrooms, the library, darkrooms, studios, and an auditorium.
