Built as an extension to the existing Orange County Performing Arts Center, the Renée and Henry Segerstrom Concert Hall is the 2000-seat home for the Pacific Symphony Orchestra. It also features a smaller 500-seat auditorium, a restaurant, a music library and a 60-foot tall sculpture by Richard Serra in front of the building. "I wanted to design a very Southern California building", Pelli said. "The undulations of the walls reflect for me a number of things: the waves of the Pacific Ocean as well as the waves of sound that will be emanating from the performers. There is a certain fluidity and ease of life that is so very typical of Southern California, and the buildings reflect that in the sense that they are elegant but not uptight. I wanted to create welcoming, friendly buildings that were very open".
