Since buying the Chateau Marmont hotel in Los Angeles in 1990, André Balazs has built a hospitality empire that includes the new Chiltern Firehouse in London and the Mercer in New York. The 58-year-old’s hotels are narrative-driven spaces that integrate design and storytelling in a refreshingly effortless way. Next on the horizon for Balazs is a Standard hotel in London, which will join Standards in New York, L.A.,and Miami.
