ACAU Architectes

What ACAU Architectes does

ACAU Architectes (legally ACAU — Agence Coopérative Architectes Urbanistes) is a cooperative architecture and urban planning firm founded in 1985 and headquartered in Rouen, Normandie, France. The firm operates with approximately 19–21 staff, including two associates (Vincent Dubillot and Flavien Blondel), 16 specialized collaborators, and administrative support, delivering architectural design services to French public sector clients. Its core offering encompasses architectural conception, rehabilitation, extension, and new construction across educational facilities (schools, collèges, crèches), cultural centers, market halls, municipal buildings, and tier-lieu conversions.

The firm specializes in sustainable construction, deploying biosourced materials (timber frame, hemp concrete, wood fiber, raw earth), geothermal heating systems, solar production, and bioclimatic design features (winter gardens, natural ventilation). Technical certifications achieved include E3C2 and E+C-. The firm operates through French public procurement competitions and direct contracting with municipalities, departments (e.g., Conseil départemental de l'Orne), regions, and public institutions (notably EPFN — Établissement Public Foncier de Normandie).

Revenue derives from project-based architectural fees, with project construction values ranging from approximately €1.35M to €11M (e.g., €11M Collège Arlette Hée-Fergant Vimoutiers, €8.5M Groupe Scolaire Marot Rouen, €10.5M Ferme du Breuil Mézidon-Canon). Missions span DIAG, BASE, EXE, and OPC phases with multi-year contract cadence. Geographic scope is primarily Normandy (Eure, Seine-Maritime, Calvados, Orne) with recent expansion into Île-de-France and Hauts-de-France. The firm holds a 40+ project portfolio and has accumulated industry recognition through Palmarès de l'Architecture, Rubans du Patrimoine, AMC's '100 bâtiments de l'année', and ArchiDesignclub awards.
