British architect David Chipperfield has been chosen to design a major expansion of the St. Louis Art Museum. The expansion will increase space by 40 percent. “The St. Louis Art Museum is bursting at its seams. Strategic acquisitions by the Museum and gifts from local benefactors have created a great collection that cannot be properly shown. Major works by such artists as Matisse and Picasso are confined to storage, and entire collections can only be viewed on a rotating basis. Chipperfield was chosen after a 10-month search.”
