The bold architecture and overwhelming scale of the Pacific Design Center, created by Argentine architect Cesar Pelli, aroused controversy when it was erected in 1975. Sheathed in gently curving cobalt-blue glass, the six-story building houses more than 750,000 square feet of wholesale interior-design showrooms and is known to locals as "the Blue Whale." 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. The long-delayed Red Building towers are scheduled to finally open in the summer of 2011. Visitors are welcome during regular business hours and one designated Saturday each month (except June-August). There are two casual Wolfgang Puck restaurants, Red 7 and Spectra.
