Developer Bill Davies has engaged Philip Johnson/Alan Ritchie Architects to investigate possibilites for the Old Main Post Office Building on West Van Buren, according to a report in the Sun-Times. Davies aquired the massive structure from the city at auction, and speculation has been rife as to what could be done with the building, which is built over several north/south rail lines. Ritchie declined elaborate on the plans. In addition to the future of the Post Office, we were left wondering how long Johnson’s name will remain attached to the firm. He passed away in 2005.
