Exndo Architectures

What Exndo Architectures does

Exndo Architectures is a Lyon-headquartered architecture and urban planning practice founded in 2006 by principal architect Etienne Fradin. The firm specializes in urban renewal, eco-district development, social and affordable housing, heritage building rehabilitation, and mixed-use programs, serving real estate developers, social housing organizations (HLMs), and municipal authorities primarily across the Auvergne-Rhône-Alpes and Bourgogne-Franche-Comté regions. Its service portfolio spans full architectural design from concept through completion, urban planning for large-scale district reconversions, building rehabilitation (including thermal retrofit), and senior living facility design, with notable projects such as the Walden ecoquartier in Cognin, the Tour Guillot and Îlot Bourdeix reconversion, the CERA Lyon Part-Dieu project with Sou Fujimoto Atelier and Dream, and the Dardilly Esplanade.

The firm operates as a traditional project-based architecture atelier, earning revenue through custom fee quotations tied to project scope, complexity, and client requirements rather than standardized pricing. Its go-to-market relies on direct engagement with enterprise and public-sector clients, active participation in architectural competitions, professional referrals, and visibility through industry publications. Headcount is limited to 1–10 employees, and the firm has not raised external equity capital beyond a 2006 AGORANOV incubation; growth is dependent on the founder's capacity and on ad hoc multidisciplinary teams assembled with named engineering consultancies, landscape architects (Wabi Sabi, Base, Canopée), and peer architecture firms (Encore Heureux, Atelier Martel).
