What OECO Architectes does
OECO Architectes is a French architecture and landscape design firm headquartered in Toulouse, founded in 2012 by three female architects — Claire Furlan, Vanessa Larrère, and Coralie Bouscal — operating under the philosophy of "Oeuvre Collective" (Collective Work). The firm delivers project-based architectural services across residential, educational, cultural, healthcare, sports, tertiary, and public infrastructure sectors, with a consistent technical focus on ecological and bioclimatic design using local, biosourced materials (wood, compressed earth blocks, stone) and multiple environmental certifications (RE2020, NF Habitat HQE, Effinature, NoWatt). The practice operates from a single Toulouse office at 10 Rue Bertrand de Born, with a team of approximately 12-15 people including six HMONP-credentialed architects.
The firm operates a pure project-based services business, with no SaaS, software, or platform offering. Customer acquisition is bifurcated: public sector projects (schools, universities, cultural centers, social housing, archives) are won through competitive tenders ("concours") organized by municipalities and regional bodies, while private developer commissions (GREEN CITY, Crédit Agricole Immobilier, SPORTING Promotion, SA HLM des Chalets, Nexity) are negotiated directly. Pricing is fee-based on disclosed construction project budgets ranging from roughly €1M to €70M, with architecture fees ranging from 8-12% of construction cost. Notable landmark projects include the €17.29M Logements Factory (Toulouse, 2021), the €18.8M Tiers Lieu des Halles de la Cartoucherie (delivered 2023-2024), and a 2014 finalist placement in the international competition for the €70M National Museum of Ethnography in Budapest.
Revenue and financial figures are not publicly disclosed, and no funding rounds, acquisitions, or external institutional investment are evidenced. The firm is independently owned by its three co-managing partners (cogérantes), with an active project pipeline running into 2026 and a portfolio of industry recognition including Equerre d'Argent (2011), Pyramide d'Or (2019), WATA (2019), 40 Under 40 (2020), and Fibois Occitanie/Nouvelle-Aquitaine (2023, 2025). Geographic concentration remains in southern France — principally Occitanie and Nouvelle-Aquitaine — with limited international engagement outside the single Budapest competition.

OECO Architectes competitors and assessment
Company assessmentDirect peers
- TETRARC: French architecture firm based in Nantes/Toulouse with similar mix of public and private commissions across education, housing, and culture. Comparable project scale and typology, often competing in the same concours circuits.
- Dominique Coulon & Associés: French architecture firm of similar size and typology, with strong public-sector client base (cultural, education, housing) and a comparable award-winning portfolio. Most directly comparable French peer on scale, sector mix, and design-led positioning.
- Atelier Architecture King Kong: French architecture studio with strong public-sector portfolio (cultural, education, urban regeneration) and a similar design-led, sustainability-sensitive positioning. Competes in adjacent regional concours to OECO.
- Mateo Arquitectura: Independent architecture studio based in Barcelona, comparable in scale to OECO, with strong emphasis on ecological materials, bioclimatic design, and integration of landscape and architecture. Closest non-French peer on design philosophy.
- Lacaton & Vassal Architectes: Paris-based French architecture firm recognized for sustainable design and social housing transformation (2021 Pritzker Prize). Comparable to OECO in its focus on ecological sensitivity, social-housing typology, and material-driven innovation.
Emerging players
- Studio Mumbai: India-based architecture studio comparable to OECO on emphasis of local materials, craft-based construction, and sustainability. Comparable in ethos and project scale for cultural and public commissions.
Broad incumbents
- Snøhetta: Internationally recognized architecture and landscape practice with strong sustainability credentials and cultural/ public typology overlap. Comparable design philosophy and landscape-integration ethos, but at much larger scale and global reach.
- Foster + Partners: Globally established architecture firm with broad public, cultural, and commercial portfolio. Comparable on sustainability positioning for large public commissions, though vastly larger scale and geographic reach.
- Architecture-Studio: Larger established French architecture firm with global footprint across cultural, public, and commercial sectors. Overlaps with OECO in French public and cultural project typologies but operates at materially larger scale and broader geography.
- Renzo Piano Building Workshop: Global architecture firm with significant cultural and museum portfolio (similar to OECO's Budapest museum competition context). Operates at much larger scale and is comparable on design prestige rather than commercial overlap.
