Stoa

What Stoa does

Stoa is a French architecture and urban planning agency founded in 1992 and headquartered in Marseille at 7 rue d'Italie. The firm delivers integrated design services across public space development, mobility infrastructure, and civil engineering works — including tramway systems, pedestrian bridges and footbridges, urban development zones, and active transport infrastructure. Its service portfolio is organized around three core programmes: Projets Fondateurs (foundational urban projects such as the Le Quai Rauba Capeu waterfront in Nice and the ZAC des Hibiscus master plan in French Guiana), Ouvrages d'Art (art and crossing structures including the Saint-Estève Janson footbridge shown at the 2016 Biennale de Venise), and Mobilité (tramway, bus rapid transit, cable transport studies, and parking/mobility hubs). Core technology is conventional architecture and urban design practice — there is no proprietary software platform, no AI component, and no digital product layer; the offering is professional services rendered through drawing, modeling, and project management from concept through delivery.

The firm's business model is project-by-project fee-for-service engagement with public-sector clients via competitive tendering and direct commissions. Pricing is not publicly disclosed. Customer base is exclusively French municipal, metropolitan, and public development agencies (Marseille Provence Métropole, Métropole Aix-Marseille Provence, EPAG Guyane, Ville de Nice, Ville de Strasbourg, Communauté d'agglo Arles Crau Camargues Montagnette), and the firm collaborates with engineering and construction partners (Bouygues, SMM, Setec, Sitétudes, Rudy Ricciotti) under consortia structures typical of French public infrastructure procurement. Geographic coverage spans mainland France, French Guiana, and selective international projects in Karlsruhe (Germany) and Geneva (Switzerland). A parallel Théorie and Enseignement activity, led by founding principal Pascal Urbain, produces published architectural theory and teaching content that supports the firm's intellectual positioning but is not a separately monetized product.
