Atelier11 architectes

What Atelier11 architectes does

Atelier11 architectes is a private, independent architecture practice headquartered in Boulogne-Billancourt, France, operating with a team of approximately 12 employees. The firm delivers architectural services across the full project lifecycle—from diagnostic through work acceptance—focused on building rehabilitation and maintenance for property owners, businesses, and developers in the Paris and Île-de-France region. Its service catalog spans office transformation, office renovation, roofing renovation (including specialized zinc work), real estate agency fit-out, and consulting/AMO (Maître d'Ouvrage Assistance) project management.

The underlying technology stack is conventional professional services delivery rather than a software platform: BIM-based architectural design, on-site project supervision, and direct client advisory. There are no proprietary software products, no APIs, no AI capabilities, and no patents or certifications disclosed in the input data. Marketing and client acquisition rely on a single LinkedIn company page and the firm's WordPress-hosted website at atelier11.fr, which functions as a portfolio and inquiry channel.

Commercially, the firm operates a direct-to-client, professional services model with project-based, quote-driven engagement. Revenue is generated from architecture fees, renovation supervision, and consulting engagements, denominated in euros and reportedly in the low millions (specific figure not disclosed). The ownership structure appears to be a partner-led private practice with no parent company, no institutional investors, and no disclosed funding history. Geographic scope is single-country and limited to the Île-de-France metropolitan region.
