Atelier Didier Dalmas Architectes Associés

What Atelier Didier Dalmas Architectes Associés does

Atelier Didier Dalmas Architectes Associés is a Lyon-headquartered architectural firm founded in 1991 by Didier Dalmas, specializing in the design of public and institutional buildings. The practice operates across seven sector verticals — housing, commercial, sports, culture, healthcare, education, and events — and has completed over 100 projects since inception. Its primary client base consists of French municipalities, regional and departmental governments, social housing operators, and select private-sector developers.

The firm's service offering covers the full architectural lifecycle for public and institutional commissions, including feasibility and programming studies, concours participation, schematic and detailed design, construction documentation, and on-site supervision. Geographic execution spans the Auvergne-Rhône-Alpes region as the home market, with additional delivered projects across other French regions (including Île-de-France and Corsica) and a single disclosed international project in Mongolia. Notable clients include Ville de Lyon, Région Auvergne-Rhône-Alpes, Département du Rhône, ATMB, Cogedim, OPAC du Rhône, and Groupe SERL.

The firm operates as a small practice with 1-10 employees, with Didier Dalmas as founder and lead architect and Sonia Monnier as administrative director. Revenue is generated on a project-fee basis tied to individual architectural commissions. Long-standing collaborative relationships with engineering and design partners — including Garbit & Blondeau, Atelier Anne Gardoni, Atelier Catherine Boidevaix, Arto Architectes, and Léon Grosse — form part of the project's delivery infrastructure on larger commissions.
