Directly behind Sibley, the OMA/Rem Koolhaas and Shohei Shigematsu-designed Milstein Hall (named after Paul Milstein) is a prominent cantilevered structure housing studio space that extends over University Avenue. The LEED-certified building provides an array of features such as a stepped auditorium space for presentations and meetings, crit space, galleries, and a sunken garden. Design for the building was a grueling process, with several architects and a constantly delayed schedule. The unfinished building opened to students in the Fall of 2011, with the ceremonial completion scheduled the following Spring. In January 2013, the American Institute of Architects (AIA) gave Milstein Hall the Honor Award, its highest award. Designed by OMA, Milstein Hall was among 11 buildings in the United States and Canada that received 2013 AIA Honor Awards for Architecture.
