What Chatillon Architectes does

Chatillon Architectes is a privately-held French architecture firm founded in 1986, structured as a SARL (Société à Responsabilité Limitée) and headquartered in Paris with a registered office in Ferney-Voltaire and an international office in Geneva. The firm specializes in the transformation, restoration, and adaptive reuse of historic and heritage buildings, including listed monuments, UNESCO sites, museums, cultural institutions, sports facilities, educational campuses, and luxury hospitality venues. Its portfolio includes landmark projects such as the Grand Palais renovation in Paris, the Carnavalet Museum, the Piscine des Amiraux, the Bains Municipaux de Strasbourg, the Quadrilatère de Beauvais, the École des Beaux-Arts de Paris, and the Red Sea Museum in Jeddah, Saudi Arabia.

The firm employs approximately forty multidisciplinary collaborators under the leadership of François Chatillon, chief architect of historical monuments, and Simon Chatillon (HMONP licensed architect). Its technical approach combines heritage-specific expertise with digital diagnostic tools, including Building Information Modeling (BIM), point-cloud data capture, and synthesis models for heritage analysis — capabilities recognized by the 2022 BIM d'Or award for the Nouveau Grand Palais project. The firm uses these digital tools as part of a domain-specialized heritage diagnostic workflow rather than as a software product offering.

Chatillon Architectes generates revenue exclusively through professional services fees tied to project-based commissions, primarily acquired via public architecture competitions, government tenders, and direct commissions from institutional clients. Its client base is overwhelmingly composed of government and public-sector entities (municipalities, DRACs, Centre des monuments nationaux), cultural institutions and foundations (Le Corbusier Foundation, Royaumont Foundation, Musée Carnavalet), educational institutions (Sciences Po, École des Beaux-Arts de Paris), and selected private luxury/hospitality clients (Domaine Clarence Dillon). Pricing is project-specific and not publicly disclosed. Marketing and demand generation occur primarily through an award-laden public portfolio, publications in architecture media, conference speaking (e.g., RELEASE [AEC]), and Instagram/LinkedIn presence — not through a direct sales force.
