What rhb | architectes does

rhb | architectes (legal entity: rouby hemmerlé brigand architectes) is a Strasbourg-based architecture and urban planning firm founded in 2009 and co-managed by three partners — Julien Rouby, Julie Hemmerlé, and Nicolas Brigand — with a team of approximately fifteen collaborators. The firm provides full-service architectural design spanning competition entries through construction delivery, with a portfolio oriented toward public equipment programs, educational facilities, sports complexes, residential buildings, and public spaces. Core technical capabilities include Building Information Modeling at LOD 350 level, environmental performance analysis using RE2020-aligned Lifecycle Assessment criteria, and material reuse consulting encompassing circular-economy methods such as furniture repurposing and reclaimed-tile terrazzo.

The firm operates an exclusively public-procurement-led go-to-market, winning architectural competitions (marchés publics) issued by municipalities, communes, universities, and government agencies primarily in the Alsace and Grand Est regions, with project budgets ranging from approximately €262K to €18.4M. Notable commissions include the INSA Strasbourg School of Architecture extension and rehabilitation (€18.4M, 9,600 m²), the Université de Strasbourg Institut de Géologie renovation (€5.37M), the Groupe scolaire Finkwiller for the Ville de Strasbourg (€4.56M), and the Willgottheim Salle Multifonctions (€1.8M). Revenue is generated through professional services fees tied to project-based, multi-year contracts awarded via competitive tenders, with no standardized pricing tiers.

Strategic positioning rests on dual-credentialed architect-engineer talent trained at INSA Strasbourg, sustained teaching commitments at that institution, and a stable network of recurring specialist partners (SIB ETUDES, ECHOES, PROJEX, Solares Bauen, Kubler). The firm has accumulated reputational capital through the Prix Europe 40 under 40 (2018), Trophée Eiffel 2020, Palmarès CAUE 2016, and Palmarès du Prix National Construction Bois 2015, and it has begun extending its geographic footprint into Lyon, Dijon, and the Paris region while developing specialized environmental research and material-reuse services.
