In China’s capital city, Zaha Hadid Architects has completed the Leeza SOHO tower, a 45-story skyscraper that boasts the world’s largest atrium at 194.15 meters in height. Designed to anchor the new Fengtai business district in southwest Beijing, the futuristic tower is wrapped in a double-insulated unitized glass curtain wall system that curves around its twisting, sculptural form.
