3 Historic and Architectural Significance First modern glass skyscraper constructed in Chicago Loop. First Chicago skyscraper designed by SOM. First fully air-conditioned office building in Chicago. First use of insulated glass units in a Chicago skyscraper. Designated a Chicago Landmark in Listing on the National Register of Historic Places in process.

4 The Project The Inland Steel Building is being rehabilitated and repositioned as an office building to compete in the 2008 marketplace. Project seeks 20% federal historic rehabilitation tax credits, thereby requiring compliance with Secretary of the Interiors Standards for Rehabilitation. As a Chicago Landmark, changes to exterior and lobby are subject to review and approval by the Commission on Chicago Landmarks. A challenge of rehabilitating the Inland Steel Building for the current market is to preserve significant modern interior features while accommodating the needs of a variety of tenants.

22 Summary The Inland Steel Building is one of the defining commercial high-rises of the Post-War era of modern architecture and a beloved Chicago Landmark. A challenge of rehabilitating the Inland Steel Building for the 2008 market is to preserve significant modern interior features while accommodating the needs of a variety of tenants. The project will retain the Richard Lippold sculpture in the lobby, restore the original system of light panels on the first floor, and reveal obscured marble and textured glass features. The distinctive lighting configuration on the second floor will be restored. Inappropriate partition walls will be removed from office floors to reveal original clear span spaces. Hauserman wall panels will be retained on some floors, and a new modular partition system will be installed on remaining office floors.
