The bold architecture and overwhelming scale of the Pacific Design Center, designed by Argentinean architect Cesar Pelli, aroused controversy when it was erected in 1975. Sheathed in gently curving cobalt-blue glass, the seven-story building houses more than 750,000 square feet of wholesale interior-design showrooms and is known to locals as "the blue whale." When the property for the design center was acquired in the 1970s, almost all of the small businesses that lined this stretch of Melrose Avenue were demolished. Only Hugo's Plating, which still stands in front of the center, successfully resisted the wrecking ball. In 1988, a second boxlike structure, dressed in equally dramatic Kelly green, was added to the design center and surrounded by a protected outdoor plaza.
