What OSLO Architectes does

OSLO Architectes is a French architecture and urban planning firm founded in 2011 in Strasbourg by three co-founders — Laurent Fleury, Josselin Lutz, and Nicolas Parent — and now operating as a 65-person collective with 9 associates across Strasbourg and Paris. The firm delivers architectural services spanning residential housing (collective, student, senior, and mixed-use), educational facilities, tertiary offices, public buildings (sports arenas, schools, civic infrastructure), hospitality, healthcare, and urban brownfield reconversion, with a cumulative portfolio of approximately 15,000 housing units delivered over 15 years. Its practice is distinguished by a non-dogmatic, context-driven design philosophy, a "collective atelier" model rather than a star-architect signature, and systematic leadership on environmental and circular-economy methodologies — including RE2020, BBCA, Passivhaus, HQE Excellent, BREEAM Excellent, Effinergie+, E+C-, and NF Habitat HQE certifications, alongside off-site/hors-site prefabrication (FOB 2D timber facades, bathroom pods) and on-site material reuse (e.g., 3,800 tonnes of crushed concrete reused at Collège François Villon).

The firm serves three primary client segments: (1) major French property developers — VINCI Immobilier, Bouygues Immobilier, Icade Promotion, Eiffage Immobilier, Nexity, and Promogim — for residential and tertiary projects; (2) public-sector clients including the Ville de Strasbourg, Collectivité Européenne d'Alsace, and Grand Est region for educational and civic infrastructure; and (3) corporate/industrial clients such as Endress+Hauser France (Nexus campus, Cernay, delivered January 2026). Projects are won through architectural competitions and direct mandates, with construction values typically ranging from €4M to €58M and fees structured as a percentage of construction cost or lump-sum professional service fees.

Commercially, OSLO Architectes generated €8M of turnover in FY2025 (+10% year-over-year), making it a mid-sized French player. Distribution is entirely direct sales, with no intermediaries or marketplace channels. Marketing relies on competition wins, architectural press coverage (Business Immo, Batiactu, Le Moniteur, Archistorm), a portfolio-rich website, and active social media (Instagram, LinkedIn, Facebook, YouTube). The firm is privately held by its three co-founders with no external investors, no funding rounds, and no acquisitions. Recent strategic moves include the 2022 Paris office opening, the 2025 inauguration of a 1,243 m² low-carbon headquarters rehabilitated from an industrial building, the Pyramide d'Argent 2024 award for Osmose, and the March 2026 competition win for the École Européenne in Strasbourg.
