In 2009, the museum closed for renovation and expansion, reopening in November 2011. The project restored aspects of the original building designed by Saarinen, made necessary structural repairs, replaced windows, and upgraded mechanical systems. The renovated museum features year-round, changing exhibitions and a new Collections and Education Wing—an additional of storage and classroom space open to visitors by guided tour. Based on an open storage plan, the new wing allows the museum's entire collection to be seen.
