What Atelier PHILÉAS does

Atelier PHILÉAS is a privately-held French architecture practice founded in 1993 and headquartered in Paris, Île-de-France, with a stable team of 14 employees. The firm provides full-service architectural design and project management across eight typologies: residential (Lieux à Vivre), workplaces (Lieux de Travail), educational facilities (Lieux d'Enseignement), cultural and leisure (Culturel & Loisirs), mobility (Mobilité), memorial/ceremony (Mémoire/Cérémonie), restructuring, and mixed-use developments. Its core competencies lie in sustainable-design delivery against HQE (Haute Qualité Environnementale) and BBC (Low Energy Building) certifications, complex urban insertions, multi-phase construction in occupied environments, and the integration of landscape, structural innovation, and material detailing (polycarbonate facades, photovoltaic roofs, ETFE, green roofing) into architectural identity. Notable projects include the Historial de Vendée museum (Roux Dorlut Award 2006), the Rennes Métropole Crematorium (Prix spécial d'architecture de Bretagne 2010, Mies van der Rohe contender 2009-2010), and the Centre Aquatique Olympique for the 2024 Paris Olympics.

The firm is a core member of the PLAN.01 architecture collective alongside Atelier du Pont, Ignacio Prego Architectures, Jean Bocabeille Architecte, and Koz, a partnership structure that allows it to bid on large-scale public commissions exceeding its solo capacity. Revenue is generated through professional services contracts (architectural design, project management, and construction supervision) negotiated project-by-project with clients; fees are not publicly disclosed. The go-to-market is primarily through French public-sector architectural competitions (marchés publics), supplemented by direct engagement for private enterprise mandates and government-to-government channels for the international French Diplomatic Campus project delivered in Bamako, Mali across three phases (2002-2005). The client base is heavily skewed to French public and parapublic entities — Ville de Paris, RATP, Aéroports de Paris, Conseil Général 92, Conseil Général de la Vendée, Rennes Métropole, Ville de Versailles, Paris Habitat, SANEF, SAPN — with a secondary roster of private enterprise clients (Gaz de France, EURO RSCG/Havas, Cell Network). The firm operates an active bilingual website and maintains a presence on LinkedIn, Instagram, and Facebook; it has no patents, no external funding, and no disclosed M&A activity.
