330 North Wabash is a skyscraper in downtown Chicago, Illinois, United States, at 330 N. Wabash Avenue, designed by famed architect Ludwig Mies van der Rohe . A small bust of the architect by sculptor Marino Marini is displayed in the lobby. The 52-story building is situated on a plaza overlooking the Chicago River. At 695 feet, 330 North Wabash is the second-tallest building by Mies van der Rohe, the tallest being the Toronto-Dominion Bank Tower at Toronto-Dominion Centre. It was his last American building.The building's original corporate namesake no longer owns nor has offices in the building. IBM sold IBM Plaza to the Blackstone Group in 1996. IBM all but completed its move out of IBM Plaza as of early 2006, taking up space in the new Hyatt Center building closer to Union Station. Current major tenants are the American Medical Association, Langham Chicago managed by Langham Hotels International, and law firm Latham & Watkins.The former IBM Plaza has several design features that are rare in an office building but understandable given its original owner. The building's electrical system, environmental system, floor strength, and ceiling height can support large raised floor computing centers. Also, the "banked" intelligent elevator system is a model of efficiency and rarely keeps anyone waiting for service. IBM Plaza stayed dry during the 1992 Chicago Flood.
