What SAS Croisée d'Archi does
SAS Croisée d'Archi is a privately held French architecture firm (Société par Actions Simplifiée) founded in 2000 and headquartered in Saint-Chamond, Auvergne-Rhône-Alpes, between Lyon and Saint-Étienne. The firm specializes in the conservation, restoration, rehabilitation, and reconversion of buildings protected under France's monuments historiques regime, as well as feasibility and programming studies for heritage, tourism, and cultural sites. Its 9-person team includes three architects du patrimoine trained at the École de Chaillot in Paris, plus complementary specialists in HMONP architecture, urbanism, and construction economics, supported by an in-house administrative director.
The firm's core service portfolio is structured across five interconnected practice areas: Conservation et Restauration, Études Patrimoniales (diagnostic and heritage studies), Ingénierie Culturelle (cultural-site programming), Urbanisme (heritage-focused urban planning), and Patrimoine et Architecture Contemporaine (contemporary interventions within historic contexts). Its distinguishing technical capability is the use of 3D laser scanning, photogrammetry, and point cloud modeling for precise heritage documentation and analysis. Projects are delivered through multidisciplinary teams that include external structural engineers, MEP consultants, economists, scenographers, landscape architects, and specialist consultants in petro-archaeology and mineral materials.
Commercially, the firm operates exclusively in the French public sector, generating revenue through architectural and engineering service contracts awarded via competitive public procurement. Project budgets publicly disclosed on the firm's communications range from approximately €371K to €4.19M (e.g., Loos-en-Gohelle Fosse 11/19 at €4,185,000 HT, Annecy Église Saint-Maurice at €1,970,000 HT, Vertaizon church at €1,107,241 HT, Rumilly church at €670,000 HT, La Chaise-Dieu abbey cloister at €371,000 HT), typically structured as multi-year contracts spanning preliminary study, maîtrise d'œuvre, and phased restoration.

The firm has national reach across Auvergne-Rhône-Alpes, Île-de-France, Hauts-de-France, Nouvelle-Aquitaine, and PACA, despite its single Saint-Chamond office.
