A Propos Architecture

What A Propos Architecture does

A Propos Architecture is a privately-held French architecture firm founded in 1984, headquartered in Vertou (Loire-Atlantique) with a secondary office in Cholet (Maine-et-Loire). The firm provides architectural design services across the full project lifecycle — from feasibility studies through to construction oversight — for both new construction and the renovation/restructuring of existing buildings. Its four formalised service lines are Éco-Construction (sustainable new builds using HQE principles, bioclimatic design, and biosourced or geosourced materials), Restructuration Éco-Responsable (building adaptation for new uses under the AGEC circular economy law), Rénovation Énergétique (thermal upgrades, HVAC, ITE, and facade works aligned with RE2020), and Faisabilité (urban planning and budget pre-project analysis).

The firm’s underlying technical approach rests on life-cycle material analysis, low-carbon construction methods (low-carbon concrete, timber frame, earth brick, rammed earth, hemp insulation, algae-based paints), and expertise in managing construction on occupied sites. It holds LABEL Lucie 26000 RSE certification (since 2022) and previously maintained AFNOR ISO 9001 certification (2010-2022).

Commercially, A Propos operates a project-based professional services model, earning architectural mission fees tied to construction commissions awarded primarily through French public procurement (marchés publics) and direct engagement. Projects range from ~€224K to ~€9.95M in construction value. The customer base is dominated by municipalities, departmental councils, and public institutions across at least six departments in the Pays de la Loire and neighbouring regions, with additional private-sector and social-enterprise clients in retail, industry, and specialised facilities. Distribution is direct, via the two offices and the firm’s portfolio website, with no intermediary channels.
