What arx architecture does

ARX Architecture is a private architecture firm headquartered in Strasbourg, France, founded in 2004. The firm provides full-lifecycle architectural design and project management services — from esquisse (concept) through EXE (execution oversight), OPC (project management), and specialized missions including HQE environmental quality consulting, BIM coordination, fire safety (SSI), signage (SIGN), and wood construction (MOB) — for educational, religious/cultural, residential, and civic buildings. Its technical capabilities center on sustainable, high-performance construction: passive house standards (PASSIF), positive-energy buildings (BEPOS), BBC Effinergie, HQE certification, E+C- labeling, and bio-sourced materials, with documented proficiency in occupied-site phased construction and heritage building interventions under ABF oversight. ARX was selected by Région GRAND-EST as the REGIO.BIM pilot practitioner.

The firm operates a professional services model, generating revenue through architectural design fees — typically structured as a percentage of construction value under French public procurement — secured via competitive architectural competitions (Concours) for public mandates and direct appointments for private clients. Project values in the portfolio range from approximately €500K to over €20M HT, with the largest mandates (Lycée Professionnel Dominique Labroise at €20.9M, Nouveau Collège Mentelin at €19.7M, IFPS Besançon at €15.7M, Collège Alice Daul at €10.1M) coming from regional government bodies. Customer segments span public administration, educational institutions, religious organizations, residential developers (including social housing operators CUS Habitat and HABITAT 25), and commercial/hospitality clients, with education as the dominant vertical.

Geographically, ARX is anchored in Alsace (departments 67 and 68) and has expanded into the broader Grand-Est region (Moselle 57, Meurthe-et-Moselle 54) and Bourgogne-Franche-Comté (Besançon, Montbéliard 25), with 60+ completed projects over a 20+ year operating history. The firm collaborates with peer architectural practices as either mandataire (lead) or associate architect on larger public mandates, partnering with firms including RAL1023 Architecture, TRACE Architectes, DGH Architectes, and Art'Ur Architects, while project-owner delegations (SOLOREM, S.E.R.S, S.C.A.E.B) handle client-side coordination on government commissions.
