What l'AUC does
l'AUC is a Paris-based architecture and urban planning studio founded and led by Djamel Klouche, operating from offices at 47 rue de la Chapelle in the 18th arrondissement. The firm provides professional design services spanning urban masterplans, building transformations, public space and landscape design, housing developments, and cultural facilities. Its practice is organised around the 'non-plan' methodology, an incremental and adaptive approach to city-making that favours transformation of existing built fabric over demolition, exemplified by projects such as Les Courtillières (Pantin), Tour des Poissonniers (PARIS HABITAT, 2021-2025), Babcock, and Base Aérienne 217.
The firm's revenue model is professional services fees earned project-by-project from public and private sector clients. l'AUC acquires work primarily through national and international architecture competitions (e.g., Tirana masterplan, Singapore PLAB, National Archives extension at Pierrefitte-sur-Seine) and direct commissions from French ministries, municipalities, regional authorities, and private developers (Immobel, Lamotte, Quadral Promotion, PARIS HABITAT). On large projects the firm serves as mandataire within multidisciplinary consortia, partnering with landscape architects (Mosbach Paysagistes, Bureau Bas Smets), engineers (Bollinger+Grohmann, ARCADIS), and other architecture practices (51N4E, Office KGDVS, Baukuh, Jaspers-Eyers). Pricing is not publicly disclosed and is negotiated per engagement.
l'AUC's client base is dominated by French public-sector entities (Ville de Paris, Ministère de la Culture/OPPIC, Région Île-de-France, SPL Lyon Part-Dieu, Lille Métropole, EPAU), supplemented by private developers and a growing portfolio of international public clients across Belgium, Switzerland, Albania, Singapore, the Czech Republic, and China. The firm is internationally recognised through the Grand Prix de l'Urbanisme 2021 (France's highest urban planning honour) and the UIA 2023 Patrick Abercrombie Prize, and codifies its practice through publications including 'Grand Paris Stimulé' (2009), 'Augures' (2022), and 'How to Not Demolish a Building' (2023).

l'AUC competitors and assessment
Company assessmentDirect peers
- 51N4E: Belgian architecture and urbanism practice of comparable scale with an identical focus on adaptive transformation, public space, and European masterplanning. Direct consortium partner on multiple l'AUC projects (How to Not Demolish a Building, Tangram, Cityzen) and the closest like-for-like peer in the market.
- Agence Ter: French landscape/urbanism practice operating at the intersection of public space, landscape, and masterplanning. Comparable in scale and methodology, frequently competing for the same Grand Paris and EU sustainable-city commissions.
- KCAP (Kees Christiaanse): Rotterdam/Düsseldorf/Zurich urban planning and architecture practice of similar size, with a comparable track record of large European masterplans (Zürich, Wien, Helsinki) and a similar focus on transformation over demolition.
- TVK (Trévelo & Viger-Kohler Architectes Urbanistes): Paris-based architecture and urban planning practice of similar size, competing for the same Ville de Paris, EPA, and French public commissions. Strong overlap on metropolitan-scale masterplans and competition-driven GTM.
Broad incumbents
- MVRDV: Dutch architecture and urbanism practice with a strong track record in European masterplans and mixed-use transformations. Operates at significantly larger scale but competes for the same international public and developer-led commissions.
- Dominique Perrault Architecture: Paris-based architecture practice with a strong portfolio of public buildings and European masterplans. Comparable in positioning and Parisian base, but materially larger and more focused on signature cultural architecture.
- BIG (Bjarke Ingels Group): Copenhagen/New York architecture and urbanism practice with a strong track record in masterplans, adaptive reconversion, and large mixed-use projects. Larger scale and global brand but overlapping client base in Western European public tenders.
- OMA: Rotterdam-based global architecture and urbanism firm with deep public-sector masterplan credentials. A frequent competitor on the largest international tenders (Tirana-style civic projects) and an aspirational reference point for any European urban planning practice.
- Lacaton & Vassal: French architecture practice (2021 Pritzker Prize) known for transformation and social-housing reconversion, directly overlapping l'AUC's Tour des Poissonniers and Cergy UP 70's typology. Larger team and higher public profile but same French anchor.
- Architecture-Studio: Larger French architecture practice with significant international presence (Shanghai, Paris, Dubai). Competes for the same cultural, civic, and large mixed-use commissions as l'AUC, with a broader portfolio and bigger in-house resources.
