What Co-Architectes does
Co-Architectes is a privately held French architecture firm (SARL) founded in 2005 by Nicolas Peyrebonne and headquartered in Saint-Pierre, La Réunion, with a satellite office in Longoni, Mayotte. The firm provides full-scope architectural services — design, conception, and construction supervision — across residential, educational, sports, cultural, and public-administration building typologies. Its core technical differentiator is a domain-specialized practice in tropical bioclimatic architecture: designs that establish passive climatic, urban, landscape, and cultural integration, reducing reliance on energy-intensive cooling, and are delivered through a participatory co-design methodology that engages clients, partners, and end-users from project inception. The firm also experiments with local and sustainable materials, including compressed earth bricks (BTC), regional wood species, and a newly initiated bamboo construction filière in Mayotte.
The firm's revenue model is professional-services-based, with fees calculated as a percentage of construction cost or as fixed fees tied to mission scope (complete or partial missions), and contracts typically span multi-year project horizons from design through construction supervision. Pricing is project-based and not publicly disclosed; documented project sizes range from a €177,000 private residence (Case O-I, 140 m²) to social-housing programs with construction budgets of €1M to €55M. Go-to-market is enterprise field sales: direct participation in public tenders and direct commissions for private clients, supplemented by a portfolio website, social media channels (Facebook, Instagram, LinkedIn, YouTube), and editorial publications (Matière Péi, Piya News, Atelier Ya'Hazi) hosted on Issuu.
The customer base is dominated by the public sector — French overseas municipalities (Commune de Sada, Ville de Sainte-Rose), departmental and state bodies (Vice-Rectorat + DEAL Mayotte), and social-housing operators (SIDR, SEMADER, SODEGIS) — with a smaller private residential segment. The firm operates as a partnership-style SARL with no external investors, parent company, or institutional backing; ownership is concentrated with the founder and named associates (Philippe Bayard, Marine Martineau, Pascale Mkadara). Approximately 15 staff are distributed across the two offices, including multiple HMONP-qualified architects, and the firm partners with a deep bench of specialty engineering consultancies on each project.

Co-Architectes competitors and assessment
Company assessmentDirect peers
- WOHA Architects: Singapore-based architecture practice globally recognized for tropical, bioclimatic, and green-integrated design. Directly comparable to Co-Architectes in applying passive cooling, vegetation, and tropical climate strategies to public and residential typologies.
- Encore Heureux: Paris-based architecture firm specializing in sustainable, low-cost, and participatory design, and a known strategic partner of Co-Architectes on flagship Mayotte public projects. Highly comparable in tropical/sustainable methodology and public-sector focus.
- Lacaton & Vassal: French architecture firm (Pritzker Prize 2021) renowned for sustainable social housing and the adaptive reuse of existing structures. Comparable to Co-Architectes in delivering social housing and publicly-commissioned architecture in the French system.
- Atelier Bow-Wow: Tokyo-based practice focused on contextual, site-specific architecture and behavioral urban studies. Comparable to Co-Architectes in participatory methodology and in treating local context as the central driver of design decisions.
- Studio Mumbai: Indian architecture practice known for contextually rooted, materially-driven design using local crafts and resources. Comparable to Co-Architectes in emphasizing local materials, participatory process, and site-specific tropical architecture.
- Kengo Kuma and Associates: Tokyo-based practice emphasizing natural and locally-sourced materials and contextual design. Comparable to Co-Architectes in material experimentation (bamboo, local woods) and a regionalist approach to contemporary architecture.
Broad incumbents
- BIG (Bjarke Ingels Group): Global architecture practice working across cultural, civic, residential, and commercial typologies with sustainability integrated into design briefs. Comparable in typological breadth and sustainability orientation but at vastly greater scale.
- Shigeru Ban Architects: Global practice recognized for innovative structural systems, material innovation (including paper and timber), and humanitarian/disaster-recovery work. Comparable in material experimentation and socially minded public commissions.
- Snøhetta: Global architecture and design firm with a strong sustainability and contextual design ethos. Comparable in design philosophy but operates at much larger scale and across many geographies, making it a broad incumbent rather than a direct competitor.
- Foster + Partners: Large global architecture firm with a long-standing commitment to sustainability and notable experience designing in tropical and hot-climate contexts. Comparable in sustainable design intent but operates at a much larger scale across all major building typologies.
