From the mid-1990s until 2005 the IMA focused on the next phase of development, the "New Vision", or what became known as the "New IMA".[23] After four years of restoration, the Oldfields mansion reopened to the public in June 2002[23] and was designated a National Historic Landmark in 2003.[24] In 2005 the museum completed a three-year, $74 million renovation and expansion project that added three new wings and 50 percent more gallery space to the building.[25] In all, the construction added 164,000 square feet (15,200 m2) to the museum, in addition to the renovation of 90,000 square feet (8,400 m2) of existing space.[25] Renovations included the Hulman and Clowes Pavilions, which house the museum's European collection, as well as the addition of the Allen Whitehill Clowes Gallery.[25] The expansion aimed to unify the building and campus while creating a more welcoming atmosphere for visitors.
