The Leo Burnett Building, located on 35 West Wacker Drive at North Dearborn Street in the Chicago Loop, is a 50 story, 635 foot (193 m) tall skyscraper above the Chicago River's Main Stem on the southern bank. When built in 1989, it was the 12th tallest structure in Chicago. It was designed by Kevin Roche-John Dinkeloo and Associates and Shaw & Associates. It is a postmodern design made with granite, masonry, glass, steel and concrete. The windows are divided by stainless steel bars, which is typical of "Chicago windows."
It houses advertising agency Leo Burnett Worldwide, owned by Publicis, from which it derives its name. The building is also home to the law firm of Winston and Strawn and the restaurant Catch 35. Media services agency Starcom Worldwide, also owned by Publicis, has its headquarters located in the building.RR Donnelley moved its corporate headquarters to this location in May 2015.
