What Bourdet Rivasseau Architects does

Bourdet Rivasseau Architectes is a Rennes-based architecture firm founded in 2011 by Hermine Bourdet and Rachel Rivasseau, operating as a French SARL with €141,660 in capital and a six-person team. The firm provides architectural design services across collective housing, participatory housing, intermediate housing, public facilities (social centers, nurseries, youth and disability housing, EHPAD senior care facilities), and tertiary office buildings, primarily in the Rennes metropolitan area and broader Brittany region with selective projects in Normandy and elsewhere in France. Its technical differentiator is a rigorous bioclimatic design methodology emphasizing natural light, structural efficiency, low-carbon and biosourced materials (timber frame, Douglas fir, tinted concrete), and systematic integration of French environmental standards including RE 2020, RT 2012/2020, NF HQE Habitat, Passiv'Hauss, Label E+C-, BBC, Label Biosourcé, and Label Bâtiment Bas Carbone.

The firm's business model is professional services revenue through project-based fees, sourced from two channels: competitive public tendering (marchés publics) for institutional clients and direct commission from private property developers and housing cooperatives. Pricing is custom-quoted per project and not publicly disclosed. Customer segments are split horizontally between residential developers/property developers (both public social housing operators and private developers) and public institutions/local government. The firm has secured multiple industry recognitions in 2024 (Prix Terre Cuite 2024 National First Prize ex aequo, Prix d'architecture 2024 from 10+1 D'Architectures, Prix Fibois 2024 Bretagne) and national publication features in D'Architectures and AMC in 2025. The company is registered with the Ordre des Architectes under number S16075 and operates without external investment, parent company, or subsidiary relationships.
