ATELIER CARRE D'ARCHE

What ATELIER CARRE D'ARCHE does

Atelier Carré d'Arche is a private French architecture partnership (cabinet d'architectes) founded in 1990 and headquartered at 200 rue de Lazenay in Bourges (Cher, Centre-Val de Loire). The firm provides full-service architectural design across diverse building typologies — sports facilities, educational institutions, cultural venues, healthcare and social facilities, social and private housing, office/commercial/industrial buildings, and urban planning — for public-sector clients (regional and departmental councils, municipalities, ministries, public hospitals, social housing operators) and private developers. Project delivery follows the French Loi MOP framework for public commissions and direct negotiation for private mandates, with mandates won predominantly through architectural competitions (concours).

The practice operates as a collective model with 6 architects, a designer/plastician, an economist, and two administrative assistants, led by founding associates Donatien Senly (DPLG, Paris UP9, 1993) and Olivier Audebert (DPLG, Paris UP6, 1991). Core technology relies on BIM methodology, full 3D numerical mockup, image synthesis, virtual/immersive reality, and CAD, with digital tool investment dating to the early 1990s. The firm holds expertise in environmental certifications — HQE, BEPOSS (energy-positive), BBC, E+C-, and RT2012 — applied across both new-build and heritage rehabilitation projects, including UNESCO-adjacent and Napoleon III-era sites.

Revenue is project-based professional services income from architectural fees, with no published rate cards; pricing is negotiated per project under Loi MOP or private commission. Geographic reach is centred on Centre-Val de Loire with extensions into Yonne, Allier, Nièvre, Loir-et-Cher, and Île-de-France (via the 2015-created CARRE D'ARCHE GRAND PARIS association with Anne-Laure Pozzo-Deschanel). A Public-Private Partnership with Bouygues secures recurring collège mandates for the Département du Loiret, and the firm collaborates with scenographers, urbanists, and other regional architecture practices on a project-by-project basis.
