Onyx served as an advisor to the City of Riverside to determine the feasibility of restoring and rehabilitating the theater, originally designed as a vaudeville and movie house. The structure was largely intact, although the stage and stage house didn’t meet contemporary standards for performing arts. Creative solutions were developed to modify the stage, while retaining the audience chamber. Onyx also completed a conceptual site master plan for the adjacent city block. The theater occupies a quarter of a block and, in an attempt to address the adjacent sites, complementary structures which housed vertical circulation and other functions for the theater — as well as retail — office uses and a parking structure option were designed. The design incorporated other significant historic structures on the block into the block-wide conceptual design.
