ARCHITECTURE ET HERITAGE

What ARCHITECTURE ET HERITAGE does

Architecture Et Heritage (legal entity: Architecture & Héritage, SAS d'architecture) is a French heritage architecture firm founded in 2021 and headquartered in Villeurbanne with a secondary office in Arles. The firm specializes in the conservation and restoration of historic buildings, including protected monuments historiques and unprotected heritage structures, serving French municipalities, public bodies, and select private owners across Auvergne-Rhône-Alpes and Provence-Alpes-Côte d'Azur. Services span diagnostic studies, complete MOE (Maîtrise d'Œuvre) missions, emergency consolidation work (notably post-seismic stabilization), and OPC coordination, with specialized techniques including laser cleaning of sculptures, dynamic anoxia treatment for xylophagous insects, micropile buttressing, and H-BIM digital documentation on the Parc archéologique de Fourvière project. The team of approximately five to seven comprises President Renzo Wieder, five architect collaborators with credentials from the Centre de Hautes Etudes de Chaillot and ENSAs, an art historian for documentary studies, and an administrative manager.

The business operates as a professional services firm acquiring projects through direct engagement and public procurement, with project budgets typically ranging from €132K to €1.8M for standard municipal mandates and reaching €11.8M for the Ville de Marseille Eglise des Réformés campaign. Notable engagements include the Basilique Sainte-Marie-Madeleine (St-Maximin-la-Ste-Baume), Abbaye Notre-Dame de Sénanque (Gordes), Eglise Saint-Bruno (Lyon), Co-cathédrale Notre-Dame (Bourg-en-Bresse), Eglise des Réformés (Marseille), Hôtel d'Arlatan (Arles), and the Parc archéologique de Fourvière (Lyon). Pricing is project-based and quote-driven rather than published; the firm delivers via multidisciplinary partnerships with restoration contractors, structural engineers, economists, and digital specialists such as ABIME.

Revenue mechanics rely solely on professional services fees tied to individual restoration project budgets, with no subscription, product, or recurring revenue component. The customer base is concentrated in French public-sector heritage owners, and the firm operates exclusively within France with no disclosed geographic expansion plans or external capital. The competitive positioning rests on credentialed heritage architecture expertise (HMONP, Chaillot training), a portfolio of completed protected-monument projects functioning as a procurement credential, and early adoption of H-BIM documentation methodology for complex archaeological and heritage sites.

Direct peers

• Studio Milou Architecture: Paris-based heritage architecture firm specializing in restoration of historic monuments, museums, and cultural institutions. Comparable in scope (churches, châteaux, cultural venues) and uses similar MOE/OPC mission structures for public clients.
• Pierre-André Lablaude: Senior ACMH chief architect specializing in religious heritage and historic monuments. Comparable clientele (DRAC, municipalities, dioceses) and similar scope of cathedral, church, and palace restoration projects.
• Atelier Roland Schweitzer: Long-established Parisian heritage architecture practice (Roland Schweitzer) renowned for major monument restorations and Louvre-related works. Directly competes for the same Monument Historique tenders from French municipalities and the Ministry of Culture.
• Pierre Bortolussi Architecte: Independent French heritage architect (ACMH-trained) operating on church, abbey, and château restorations across France. Same niche, similar MOE-mission delivery model, and comparable public-sector client mix.
• Jean-François Lagneau: ACMH chief architect with extensive experience in major French monument restorations including UNESCO-listed sites. Same competitive set for the largest heritage tenders.
• Architectes en Chef des Monuments Historiques (ACMH): The professional body of France's chief heritage architects, holding the monopoly on state-commissioned monument historique restorations. Direct competitor for high-profile public heritage tenders, with substantially deeper bench strength and decades of ministerial relationships.
• Frédéric Didier Architecte du Patrimoine: Independent heritage architect with Chaillot training, focused on restoration of historic religious and civic buildings. Closely comparable in team size, training pedigree, and project typology.

Others

• Centre des Monuments Nationaux: Public agency that owns and operates many of France's most visited historic monuments. Acts as both a potential client (commissioning restoration studies) and a peer ecosystem participant in shaping heritage practice standards.

Broad incumbents

• Bouygues Bâtiment Centre Sud-Ouest / Heritage: Large general contractor with a heritage restoration practice. Competes indirectly as a turnkey alternative to MOE-led architect-led delivery for major monument restoration projects.
• Vinci Construction France - Patrimoine: Major French construction group with a heritage/restoration division that competes on the same nonresidential heritage projects but from a contractor rather than architect perspective. Far larger scale with broader geographic and capability footprint.
