Now recognized as one of America's preeminent architectural firms, Hardy Holzman Pfeiffer Associates first appeared on the scene in the late 1960s with a series of highly innovative designs that took the profession by storm. During the twenty-five years of HHPA's practice, the firm has maintained their spirit of collaboration and experimentation while expanding into larger-scale and more ambitious projects. This monograph spans Hardy Holzman Pfeiffer's entire history, including their restorations of distinguished older buildings and their designs for distinctive new structures. Among the forty-nine projects presented in depth are such renovations as the Cooper-Hewitt Museum, the Brooklyn Academy of Music Majestic Theatre, the Rainbow Room at Rockefeller Center, and the Los Angeles Central Library, as well as new buildings such as Orchestra Hall in Minneapolis, Boettcher Concert Hall in Denver, BEST Products Headquarters, and the Robert O. Anderson Building at the Los Angeles County Museum of Art. Detailed descriptions and numerous illustrations accompany the built work, significant unrealized projects, and commissions now in progress. A catalogue of work and a bibliography complete the volume.
