ARCHITECTURE PATRIMOINE

What ARCHITECTURE PATRIMOINE does

Architecture Patrimoine is a Bordeaux-headquartered architecture firm founded in 1995 that specializes in the restoration and conservation of French Monuments Historiques. The practice is anchored by three associated partner-credentialed heritage architects — Denis Boullanger, Philippe Leblanc, and Delphine Gramaglia — each holding the Architecte du patrimoine diploma from the Ecole de Chaillot, supported by four collaborators (two DE/HMONP architects, one architect collaborator, and a technical secretary) for a total headcount of seven. The firm delivers services across civil, religious, private (castles, mansions), industrial and viticultural, urban, and military heritage categories, with end-to-end engagement spanning preliminary studies, project management, and construction supervision.

The firm's core service is the production of regulatory-compliant restoration architecture for buildings classified or inscribed as Monuments Historiques, an activity governed by French heritage law (ABF and DRAC oversight). Underlying capabilities include structural consolidation, facade and material restoration, historical authenticity preservation, and — as evidenced by the 2020-onward Chantier Médiéval de Guyenne engagement — experimental medieval-construction methodology. The practice executes these services either directly or as co-traitant in groupements with engineering partners, as demonstrated by its 2024 selection within the ETPO/BRLi/Architecture Patrimoine consortium for the €31M Fort Boyard protection and restoration project. There are no software products, APIs, or technology-platform components to the offering; the deliverable is professional services against project-based fees.

The business model is project-based professional services delivered on multi-year contracts. Revenue is generated through design, project-management, and technical-consulting fees negotiated per project based on scope, complexity, and client type (public vs private); no public pricing exists. Clients are split across three horizontal segments: government/municipal entities (e.g., Mairie de Mazion €518k church restoration, Département de la Charente-Maritime, Région Nouvelle-Aquitaine for the €1.6M Domaine de Malagar), private property owners (e.g., Château de Fargues €4.48M, St Emilion medieval-to-guesthouse €3.1M), and religious institutions. Go-to-market is enterprise field sales through competitive public tenders, direct private-owner relationships, and partner-led referrals; the firm actively leverages earned media (Sud Ouest, Le Moniteur, France 3) as a top-of-funnel awareness channel. Operating footprint spans southwestern France — anchored in Nouvelle-Aquitaine — with active projects in Charente-Maritime, Dordogne, Landes, and Bassin d'Arcachon.
