aquatic park when it opened in 1954. Luckman, who had known Disney for years, recounts hearing Disney describe his concept of Disneyland during lunch in April 1952. He came back with a preliminary design for a seven-acre Disneyland but Disney rejected the concept for being "too small". Luckman said, "I called a halt. Building that Disneyland that big, or bigger, would not only require a larger site than the one on Riverside, it would also require money that Walt Disney did not have." Despite his rejection, Disney hired Pereira and Luckman to design the Disneyland Hotel, which originally consisted of a two-story guestroom complex with shopping, dining and recreational facilities. In 1958, Pereira and Luckman designed the Union Oil Center (now the Los Angeles Center Studios) for the Union Oil Company of California. The Miesian-style hexagonal tower includes a rectangular inner courtyard, two low tower wings, a large subterranean parking garage, and elevated pedestrian bridges connecting to an auditorium and cafeteria building. The tower has distinctive angled front and rear façades covered with a grid of thin aluminum louvers protecting the offices within from the sun. Upon its completion, the Union Oil Center became the highest building in downtown Los Angeles at the time. In a disagreement over approaches to architectural and marketing practices, Pereira and Luckman split in 1958. Charles Luckman Associates After parting ways in 1958, Luckman went on to establish his own firm, Charles Luckman Associates. The firm soon had offices in Boston, Chicago, and Phoenix, in addition to Los Angeles, and by 1968 was one of the country's five largest architectural practices. In April 1960, a $50 million overall revamp project of the airport, known as the "Los Angeles Jet Age Terminal Construction Project", began at the Los Angeles International Airport. Luckman, along with his former partner, Pereira, and Welton Becket of Los Angeles, were contracted to design the Theme Building. The Theme Building was a concept that Luckman had in mind since 1953. In the original conception, the Theme Building was to be a much larger structure that would have consisted primarily of a glass dome that was meant to be LAX's main ticketing area and terminals. However, the plan was scaled back dramatically before construction even began. The Theme Building would have also hosted a revolving restaurant, giving patrons a 360-degree view of the surrounding area. The mechanism soon proved to be too costly
