What Rougerie Tangram does

Rougerie+Tangram is an international architecture, urban planning, and landscape design agency headquartered in Marseille with a secondary office in Paris, founded by Jacques Rougerie and operating as a privately held SAS (RCS Marseille 344 311 808). The firm is structured around three verticals — Earth, Sea, and Space — and runs a dedicated research arm, Le Lab R+T, focused on biomimicry, bio-climatic design, bio-sourced materials, 3D printing, BIM, and applied AI in architecture. Its work spans cultural and scientific venues (museums, aquariums including Europe's largest, NAUSICAA), aquatic and Olympic sports facilities (Marina du Roucas Blanc for Paris 2024), urban requalification (Marseille Vieux-Port), educational and tertiary buildings, and specialized marine and underwater infrastructure such as habitats, vessels, artificial reefs, and underwater lounges for cruise ships (Ponant's Blue Eye).

The firm competes for projects primarily through international architecture competitions and direct commissions, serving government agencies, municipalities, large institutional bodies, and private developers across more than ten countries (France, China, India, Japan, UAE, Egypt, Monaco, French Polynesia, Myanmar, USA). Notable contract values include the €8 billion Monaco marine urbanization, the €150 million Shenzhen International Maritime Museum, the €120 million La Marseillaise Tower, the €85 million NAUSICAA, and the €72 million Vieux-Port project. Co-development relationships with Foster+Partners, Ateliers Jean Nouvel, Michel Desvigne, and research partners such as NASA/NOAA, the Mediterranean Institute of Oceanology, COMEX, and UNESCO extend technical reach beyond the firm's internal ~80 professionals.

Revenue is generated through professional services fees, typically structured as a percentage of construction cost or fixed project fees on multi-year engagements; pricing is not publicly disclosed. Customers are concentrated among public-sector and large institutional clients (Boulonnais Conurbation, Government of Guangdong, Government of Kerala, Supreme Council of Antiquities, Brest and Cherbourg Urban Communities, Métropole Aix-Marseille-Provence, UNESCO), with selected private clients including Barwa, Minami International, the Bin Laden Group, SAS La Marseillaise – Constructa, and Ponant. Ownership rests with three partners — Jacques Rougerie, Sophie Rougerie, and President Emmanuel Dujardin — with no external venture or institutional capital.
