Between 2001 and 2012, the 1958 and 1983 additions were demolished. A new wrap-around building, and east and west wings were constructed. Designed by Rafael Viñoly, this $350 million project doubled the museum's size to . To integrate the new east and west wings with the Breuer building to the north, a new structure was built along the south side of the 1971 addition, creating extensive new gallery space on two levels, as well as providing for a museum store and other amenities. Viñoly covered the space created by the demolition of the 1958 and 1983 structures with a glass-roofed atrium. The east wing opened in 2009, and the north wing and atrium in 2012. The West Wing opened on January 2, 2014.
