Founded in 2001 by Nicola Delon and Julien Choppin, Encore Heureux claims a general practice for designing buildings, installations, games or exhibitions. Winner of the New Albums of Young Architects in 2005, the agency designed and delivered several cultural and tertiary buildings, public and private (concert hall, cinema, museum, innovation center). In 2014, the architects curated the exhibition Matière Grise at the Pavillon de l’Arsenal in Paris on the theme of the reuse of materials in architecture. In 2015, the agency won the scenic design concept for the Paris-Le Bourget site for COP21 and created the Pavillon circulaire, an experimental architecture demonstrating re-use possibilities. Since 2016, Sébastien Eymard has joined the adventure as a third partner and the agency has settled in CENTQUATRE-PARIS. The team is now composed of about twenty architects and develops about fifteen projects throughout France..
