What archi5 does

archi5 is a French architecture and urbanism studio founded in 2003 and headquartered in Montreuil, near Paris. The firm operates as a private limited company (SARL d'architecture) controlled by its partners — including Anne Pezzoni, Laurent Boudrillet, Jacques Sebbag, and a broad bench of 24+ named associates — and employs approximately 40 people across architecture, landscape, project management, tendering, and administration functions.

Its core service offering comprises three integrated lines: Architecture Services (full design through construction supervision for schools, housing, sports facilities, cultural centers, and offices), Landscape Design (biodiversity-focused urban green spaces, courtyards, and ecological landscaping integrated into building projects), and Urban Planning / Master Planning (district redevelopment and neighborhood-scale design). Technical differentiation centers on passive building design that exceeds current French environmental standards, low-carbon construction using wood framework, bio-sourced materials, and low-carbon concrete, and the in-house integration of landscape architects alongside building architects — a combination the firm highlights as distinctive. Projects are documented with explicit environmental objectives (e.g., 14 environmental goals on the Wilma Rudolph sports hall).

The business model is professional services revenue, with fees set either through architectural competitions (the primary acquisition channel) or direct commission negotiations. Pricing is project-specific and not publicly disclosed. Clients are predominantly French public-sector bodies — municipalities (Cities of Châtillon, Antony, Aubervilliers, Saint-Denis, Romainville, Nevers, Bobigny, Villiers-le-Bel), regional governments (Région Normandie), and public training institutions (BTP-CFA Île-de-France) — supplemented by private developers and public housing operators (RATP Habitat, Terralia, Vinci Immobilier, Pierreval, Interconstruction, Foncière Logement). Service delivery relies on a recurring consortium model with technical partners including Ingérop, EPDC, Oasiis, MATHIS, Mutabilis, and Tecnova Architecture. The firm maintains geographic reach across six French regions (Île-de-France, Normandie, Grand Est, Bretagne, Occitanie, Nouvelle-Aquitaine) with no disclosed international activity.
