Kaiser Center

Kaiser Center, also called the Kaiser Building, is a 28 story office building located at 300 Lakeside Drive, adjacent to Lake Merritt, in downtown Oakland, California, designed by the architectural firm of Welton Becket & Associates of Los Angeles. The property is bounded by Lakeside Drive, which terminates and joins Harrison Street at the site, 20th-, 21st-, and Webster-streets. When completed in 1960, it was Oakland's tallest building, as well as the largest office tower west of the Rocky Mountains. A three-story office/retail building adjacent to the main tower was completed in 1963. Kaiser Center was the headquarters of Kaiser Industries, a Fortune 500 conglomerate that was headed by industrialist Edgar F. Kaiser at the time the building was constructed.The building's roof garden was designed by San Francisco-based landscape architecture firm, Theodore Osmundson & Associates, and was the first built in the United States after World War II. While legend has it that Henry J. Kaiser resided in a penthouse apartment on the 28th floor, by 1960 the elder Kaiser had turned over the Oakland-based company to his son, and pursued projects based in Honolulu. It is much more likely that his son Edgar, who was in charge of Kaiser industries and a major power broker in the Bay Area by the time the building was commissioned, was the person who occupied any residential apartments. According to a National Park Service study, Edgar commissioned the architecturally significant rooftop garden after the building had been designed, inspired by the gardens of Rockefeller Center in N.Y.
