Money poured into LACMA during the boom years of the 1980s, a reportedly $209 million in private donations during director Earl Powell's tenure.[12] To house its growing collections of modern and contemporary art and to provide more space for exhibitions, the museum hired the architectural firm of Hardy Holzman Pfeiffer Associates to design its $35.3-million,[13] 115,000-square-foot Robert O. Anderson Building for 20th-century art, which opened in 1986 (renamed the Art of the Americas Building in 2007). In the far-reaching expansion, museum-goers henceforth entered through the new partially roofed central court, nearly an acre of space bounded by the museum's four buildings.[14]
