The husband and wife team of George and Evelyn Kosmak worked with the Berkeley Plywood Company on the design of two pavilions housing exhibits at the San Francisco Arts Festival in 1957. The two pavilions were conjoined and composed of shallow, 11-foot-wide vaults composed of plywood. The two pavilions measured 40 feet in length, each with an 8-foot roof cantilever. A band shell designed by the Kosmaks also used the same shallow plywood vault motif, this time composed of five smaller vaults, each 8 feet wide and 24 feet long. This collection of vaults reflected sound off of a 16-foot by 32-foot stage. The Berkeley Plywood Company marketed these plywood vaults at the time under the brand name, "Plyvault." The Los Angeles structural engineering firm, Mackintosh and Mackintosh, assisted on the design of these vaulted structures.
