Notable buildings S. R. Crown Hall, erected in 1955, was considered by Mies to be one of his greatest architectural achievements. To provide for a flexible, columnless interior, he suspended the roof from four steel girders supported by eight external columns spaced 60 feet apart. S. R. Crown Hall, home to Illinois Tech's College of Architecture, has been described as an "immortal contribution to the architecture of Chicago and the world." S. R. Crown Hall was granted National Historic Landmark status in 2001. A $15 million renovation, completed in August 2005, modernized the structure with energy-saving mechanicals and windows, along with needed technology upgrades for computers and the Internet—all while carefully preserving the architectural integrity of the building, inside and out. Additional improvements were completed in 2013.IIT Archives/2004.051/S. R. Crown Hall Collection-Historic Structure Report; IIT Archives/2012.028.02/Campus Building Blueprints.
