A third addition, known as the North Wing, was designed by Hardwicke Associates, Inc. of Richmond and completed in 1976. It included an adjacent sculpture garden with a cascading fountain, designed by landscape architect Lawrence Halprin. The North Wing was designed as the new main entrance for the museum, with a separate dedicated entrance added for the theater. It provided three more gallery areas – two for temporary exhibitions and one for the Lewis Family's Art Nouveau Collection while also housing a gift shop, members' dining room, and other visitor functions. However, the curved walls of the North Wing's "kidney-shaped" design proved to be functionally awkward and impractical, and it was later replaced. The 1976 wing and sculpture garden were later demolished to make room for the 2010 McGlothlin Wing.
