Midtown wasn't planned. It simply escaped...any coherent city planning, zoning, or vision. Some say it was Phoenix's attempt at Los Angeles' Wilshire Boulevard, the nearly 16-mile avenue from downtown LA's financial district to Santa Monica. Maybe. But Phoenix never had the economic power or urban assets to support its version of Museum Row on the Miracle Mile, Century City, Koreatown, Beverly Hills, Westwood with UCLA, and subway lines. Wouldn't want to become another LA.
The two are comparable in that both were the sites of a majority of post-1960 skyscrapers. In Phoenix, it began with the building above. A turquoise-skinned International-style box, the Guaranty Bank Building opened in March 1960, designed by architect Charles Polacek and built by contractor David Murdock (who lived a remarkable life). At 252 feet, it dethroned the Hotel Westward Ho as the tallest building in Phoenix and the Southwest. On the top floor the Cloud Club offered a spectacular view.
Over the next thirty or more years, this was the heart of city. For better and for worse.
The Camelback Towers was also complete in the photo (a mile north at Pierson). Park Central Shopping Center had replaced the Central Dairy in the late 1950s. Del Webb's Phoenix Towers at Central and Cypress Street, one of the few co-ops in the city, opened in 1957 (built in two phases). Twin mid-rise office buildings were opened two blocks south of Thomas; they eventually included U-Haul's headquarters. Midtown, still unnamed was coming together haphazardly. The central business district, including most shops and department stores, were still downtown (Fillmore to the railroad tracks, Seventh Avenue to Seventh Street).
