About Smurfit-Stone Building
Smurfit-Stone Building is a 41 story, 582 foot (177 m) skyscraper located at 150 North Michigan Avenue in downtown Chicago, Illinois. It was also known as the Stone Container Building and was formerly called the Associates Center. It is popularly referred to as the Diamond Building. Construction began in 1983 and was completed in 1984. The building, noted for its unusually slanted roof, was designed by Sheldon Schlegman of A. Epstein and Sons. The building has 41 floors of tenant space and the two spires at the top cover the main roof and HVAC equipment. Although the building looks as though it is split down the middle, the two sides are only slightly disjointed until nearing the top, where there is a gap between them. At times, its slanted roof—which has been likened to a skyscraper slashed with a knife—displays local sports slogans on its face, such as "GO BEARS" and "GO SOX". It also displayed "VOTE 2008" during the 2008 election day rally at Grant Park. At the time of its construction the Smurfit-Stone Building was considered to be a smart building, with sophisticated environmental and security controls.
