Equilibre Architectes

What Equilibre Architectes does

Equilibre Architectes is a privately held French architecture firm (SARL) headquartered at 1 place de Verdun in Mably, near Roanne in the Loire department, operating continuously since 1991 under its current legal form since July 2016. The firm provides architectural design, project management, and construction supervision services across four principal segments: public sector infrastructure (schools, hospitals, fire stations, municipal buildings), private residential construction, social/collective housing, and commercial/industrial projects. Three co-managing partners — founder Bernard Rivolier, Isabelle Garnier (Architect DPLG), and Julien Chabry (Économiste de la construction) — lead an 8-person multidisciplinary team that also includes two additional architects, a construction site conductor, a CAD/DAO designer, a construction economist, and administrative staff.

The firm's technical platform is built on Building Information Modeling (BIM) using Allplan AEC software for 3D project modeling and lifecycle data management, enabling all project stakeholders to consult and interact with the building model from conception through construction and utilization. Equilibre Architectes has differentiated technical credentials in energy-efficient and sustainable design, including Passive House (Passivhaus) expertise achieving approximately 90% lower energy consumption than existing buildings, and proficiency in BBC Effinergie, BEPOS (positive energy building), and HQE (high environmental quality) certifications. Two partners hold CEPH (Concepteur Européen Bâtiment Passif) certifications, supporting both residential and public-sector energy performance mandates.

The firm operates a professional services revenue model, charging project-based fees scoped to construction cost, complexity, and contract duration. Revenue is generated through three primary channels: public procurement (competitive bidding for government and social-housing projects), direct client engagement from the Mably office (for individual residential clients), and professional referrals within the Roannais economic basin. Disclosed project values range from approximately €660,000 to €3.4 million, with notable public-sector clients including Roannais Agglomération, Centre Hospitalier de Roanne, SDIS de la Loire, Roanne Habitat, and Loire Habitat, alongside enterprise clients in pharmacy, veterinary, and industrial logistics. Geographic reach is intentionally limited to the Roannais region of Auvergne-Rhône-Alpes, where the firm maintains 25+ years of local stakeholder relationships.
