After years of complaining about the lack of a premier architectural site for orchestral music, Parisians will have a new $260 million Jean Nouvel-designed hall in which to appreciate each timpani thump and bowed string. They'll have to wait a little longer, however, as the Philharmonie de Paris is slated to open in the Parc de la Villette in 2012. The Philharmonie's 2,400-seat auditorium will be sheathed in aluminum and topped with a 170-foot-tall sail-like structure. Nouvel is also making waves with the "waterfall" facade he has designed for a $150 million, 23-story condo complex in New York. Using windows in a variety of sizes and tilted at various angles, the ultraluxe building will catch light and shimmer like running water. As asking prices for the new residences reach as high as $22 million, the view might be best afforded from the outside.
