Originally proposed as a twelve-story office tower in downtown Minneapolis by local architect Ed Baker, the project eventually grew to 57 stories with the addition of Investors Diversified Services (IDS) and the Dayton Hudson Corporation as anchor tenants. Architects Philip Johnson and John Burgee of New York joined the project and designed the steel and glass skyscraper’s signature stepback form and its 23,000 square foot atrium. Dubbed the Crystal Court, the atrium was a public space modeled after an Italian piazza set under a dramatic glass roof and featuring a 105-foot high ceiling-to-floor water feature, potted trees, and park-like benches and chairs. On the second floor, which overlooks the Crystal Court, acts as a major node or hub for the city’s extensive skyway system of covered pedestrian walkways.
