Inland Steel Building

building, Chicago, Illinois, United States

Quick Summary

The Inland Steel Building, completed in 1958 in Chicago, Illinois, is a significant example of mid-20th-century modern architecture. Designed by the firm Skidmore, Owings & Merrill (SOM), it was conceived as two distinct towers: a 19-story office tower with a green-tinted glass curtain wall framed by stainless steel, and a 25-story service unit clad in stainless steel panels. This innovative design removed the need for interior structural columns in the office tower, allowing for unobstructed floor space and exemplifying the concept of universal space. The building is widely considered the first multistory office building to fully manifest the ideas of architect Ludwig Mies van der Rohe.1
