In 1962, E. Stewart Williams designed the new 75,000-square-foot (7,000 m 2) building in the Modernist architectural style, for the third location of the ever growing Art Museum. It continues as the location of the architecturally dramatic and innovative Art Museum and Annenberg Theater in downtown Palm Springs, at 101 Museum Drive just west of North Palm Canyon Drive, with a commanding presence at the base of Mt San Jacinto. 

The Steve Chase Art Wing and Education Center, also designed by E. Stewart Williams, opened in November 1996. The expansion included 25,000 additional square feet of art galleries, a mezzanine, a sculpture terrace, four classrooms, two art storage vaults and a 90-seat lecture hall. The entire Museum complex now encompasses 124,435 square feet (11,560.4 m 2) and is an institution poised to greet the 21st century with exciting new educational opportunities for the region and for its national and international visitors.

In 1974, architect E. Stewart Williams was commissioned to design the current building for the museum. Further growth resulted in the construction of the Doris and Walter N. Marks Administration Building and the 1996 completion of the Steve Chase Wing and the Education Center.
