This 30-acre exurban site 30 miles west of downtown Chicago was planned for office, commercial, cultural, and hotel development, including a new headquarters office building for Calamos Investments. In addition to designing the new Calamos headquarters, improvements included a speculative office building and the Hotel Arista projects. The master plan was later revised to include residential buildings on one of the former office building sites.
