Woodruff matched by $20 million raised by the museum. The building contains 135,000 square feet with about of gallery space. In 2005, Renzo Piano designed three new buildings which more than doubled the museum's size to , at a cost of $124 million. The Piano buildings were designed as part of an overall upgrade of the entire Woodruff Arts Center complex.
