C+2B ARCHITECTURE

What C+2B ARCHITECTURE does

C+2B Architecture is a privately-held French architecture firm structured as a SARL, headquartered at 129 route de Blagnac in Toulouse, France. The practice was founded in 2013 by Julien Coutineau and Julien Bellart, and took its current form in 2018 after merging with Claude Branger's team. It operates as a full-service architectural design practice with a multidisciplinary team of approximately 15 — architects, draughtsmen-projectors, a site manager, a technical and works manager, and an administrative and financial manager — and serves both public and private clients across the Occitanie region and adjacent departments.

The firm's core offering is one-time project-based architectural design services spanning new construction, rehabilitation, and extension work across education (schools, colleges, lycées), healthcare, cultural and sports facilities, collective and individual housing, and urban planning. Its technical positioning centres on low-carbon, sustainable construction: mixed wood-concrete structural systems, biosourced materials (wood, straw, compressed earth blocks), bioclimatic and passive solar design, and BIM Level 3 methodology. The practice holds a dense portfolio of recognised certifications — Bâtiments Durables Occitanie (BDO) Silver and Gold, E+C- levels E2C1 through E4C2, NF Habitat Excellent, Coq Vert membership — and has accumulated multiple regional awards.

C+2B generates revenue through one-time architectural fees negotiated per project, sourced primarily from public procurement competitions (concours) and supplemented by direct private commissions. The firm typically acts as lead architect (mandataire) and frequently operates in consortia with peer firms, most notably V2S Architectes and KOZ Architectes. In 2024 it created LOSKAN, a wholly-owned digital engineering studio specialising in numerical modeling, extending its offer beyond traditional architectural services. Pricing is not publicly disclosed and no tiered structure exists; project acquisition is driven by competition track record and prior client relationships, particularly with municipalities, the Région Occitanie, and multiple Conseils Départementaux.
