When star-architect Cesar Pelli originally designed the Pacific Design Center¹s (PDC) Red Building, Richard Nixon was president, Elvis was still alive and the Sylmar, not Northridge Earthquake, was a fresh memory. On Thursday, Pelli, PDC owner/developer Charles S. Cohen, PR head Michael Nyman and several California pols broke ground in West Hollywood, with appropriately red shovels, for the 400,000 square foot, red-glass sheathed edifice. Per Cohen, the new building will be "the ultimate creative office space," with floor-to-ceiling glass walls angled to take in Hollywood Hills and city views. The PDC's Green building is already home to major flack firms, including PMK/HBH, Rogers & Cowan and Bragman Nyman Cafarelli. And the Blue Building¹s Silver Screen Theater hosts SAG's screening series. But showbizzers know it best for its many high-profile events like HBO's post Emmy fete and Elton John's Annual Oscar night fundraiser. The new offices will occupy two mid-rise towers, built above a multi-floor parking garage, and linked by an outdoor palm garden. Expect Hollywood's party planners to salivate over the space once it's completed in 2009, wowed by its private valet entry, high-speed elevators and above street, drop-dead views. "I dreamed of this day for many long years; I thought it may never happen but now the three brothers (or sisters) will be complete," Pelli told the assembled crowd who noshed on a Wolfgang Puck catered breakfast.
