Henning Larsen has been selected to expand and transform the French Opéra Bastille, the largest opera house in Paris. Designed with collaborators Reichen et Robert & Associés, dUCKS Scéno, Peutz & Associés Acoustic Consultants and CET Ingénierie, the proposal includes a redesigned and extended public foyer that will open to street-level activity, as well as expanded infrastructure and workshop facilities, and the addition of a new 800-seat auditorium for use as rehearsal and performance space.
