What KOZ does

KOZ is a Paris-based architecture firm founded circa 2004, employing 106 people and operating as a single integrated practice specializing in sustainable, low-carbon timber construction. The firm's core technical expertise spans CLT (Cross-Laminated Timber) high-rises, post-and-beam wood structures, hybrid timber-concrete systems, and bioclimatic design adapted to varied climates — including tropical adaptations for the Gabonese Ministry of Eaux et Forêts. KOZ's portfolio includes more than 40 projects: from micro-houses (~€91K) to landmark commissions such as the SENSATIONS R+11 timber tower in Strasbourg (ranked among the top 10 tallest timber buildings globally per CTBUH), the Paris 2024 Olympic Athletes Village in Saint-Ouen-sur-Seine (8,049 m² at €22.3M HT), the X24 Rectorat de Créteil (20,700 m² at €50M HT, one of France's largest public timber buildings), and the largest all-wood sports complex in Paris (L'ATALANTE).

The firm serves three primary customer segments: public institutions and government bodies (municipalities, metropolitan authorities, public housing agencies, educational institutions and ministries); private real estate developers (Bouygues Immobilier, Nexity, Eiffage Immobilier, ALTAREA COGEDIM, Demathieu Bard Immobilier, Soprema, WELT Desarollos); and individuals / small commissions for bespoke timber homes and experimental pavilions. Projects have been delivered across most French régions and internationally in Mexico City, Quebec, Gabon, and Hungary.

Revenue is generated through project-based commissions for architectural design, urban planning, and project management services, with fees negotiated per project. Go-to-market combines competitive bidding for public procurement (municipalities, rectorates, ministries), direct commissions from private developers, and participation in high-visibility architecture competitions such as 'Inventons la Métropole du Grand Paris'. In 2025, KOZ joined AAGROUP, embedding its entire team into the AAGROUP Paris office at 12, impasse Mousset to deploy its wood and low-carbon expertise within a collective of regionally-rooted agencies, expanding delivery capacity without altering its specialist positioning. Pricing is project-specific and not publicly disclosed; individual project budgets range across roughly two orders of magnitude (€91K to €50M HT).

Direct peers

• Atelier du Pont: Paris-based sustainable architecture firm and member of the Plan01 collective alongside KOZ (collaborating on Historial de la Vendée and SILENCE). Directly comparable in its French footprint, sustainability-led design approach, public-sector and cultural building portfolio, and similar scale.
• Waugh Thistleton Architects: UK-based architecture firm recognized as a global pioneer of mass timber construction (e.g., Murray Grove, world's first tall timber residential building). Directly comparable to KOZ in its specialization in CLT and engineered timber systems for residential and public buildings, with a comparable focus on sustainability and tall-timber innovation.
• Dominique Perrault Architecture: Paris-based architecture firm led by Dominique Perrault, who authored the urban plan for the Paris 2024 Athletes Village in which KOZ coordinated 7 lots. Directly comparable to KOZ in its French-based sustainable architecture practice, public-sector client base, and involvement in landmark Paris projects, though typically larger in scale.
• Studio Gang: US architecture firm with significant mass timber and sustainability work (e.g., Arkansas Museum of Fine Arts, projects in Chicago). Comparable to KOZ in its emphasis on bio-based materials, low-carbon design, and landmark civic/cultural buildings, though Studio Gang operates at meaningfully larger scale.
• Shigeru Ban Architects: Japan-based architecture studio globally known for innovative timber and paper-tube structures, including disaster relief and cultural buildings. Comparable to KOZ in its use of timber as a structural and expressive material, advanced construction innovation, and a portfolio spanning residential, public, and humanitarian typologies.
• Haptic Architects: Norwegian architecture firm specializing in timber construction and sustainable design for public and residential projects in the Nordics. Directly comparable to KOZ in its timber-focused design practice, mid-sized firm scale, and portfolio of mid-rise residential and civic timber buildings.
• Michael Green Architecture (MGA): Canadian architecture firm widely credited with advancing North American mass timber practice (T3 Bayside, etc.). Directly comparable to KOZ in its focus on engineered timber for mid- to high-rise buildings, bioclimatic design, and cross-border commissions — including presence in Quebec, one of KOZ's active international markets.

Broad incumbents

• BIG (Bjarke Ingels Group): Denmark-based global architecture firm with notable mass timber projects (e.g., H17 in Stockholm, timber concept buildings). Comparable to KOZ in its pursuit of innovative, sustainability-led architecture, but BIG operates as a much larger, multi-disciplinary global incumbent spanning many building types beyond KOZ's timber/low-carbon niche.
• Henning Larsen: Nordic architecture firm (now part of Ramboll) with deep expertise in sustainable, low-carbon, and timber-forward design across Northern Europe. Comparable to KOZ in its bioclimatic and sustainability-led practice, but functions as a much larger multi-disciplinary incumbent serving public and private clients across geographies.
• Lacaton & Vassal Architectes: Paris-based architecture firm and 2021 Pritzker Prize laureate known for low-cost, low-carbon, socially-minded residential and public architecture. Comparable to KOZ in its French public-sector focus and sustainability ethos, but operates at a larger, more internationally celebrated scale and broader typology.
