What A6A does
A6A is a Bordeaux-based architecture firm founded in 2013 by Roberto de Uña, Michel Hardoin, and Antoine Ragonneau, operating as a SARL with three offices in southwestern France (Bordeaux, Royan, Anglet) and approximately 10-12 employees. The firm delivers architectural design services across residential, educational, cultural, healthcare, and mixed-use typologies, with a portfolio of 50+ projects and cumulative construction value exceeding €100M. Its signature offering is the proprietary 'Volume Capable' housing concept — developed in collaboration with architect Youssef Tohmé — a modular evolutive system in which units are sold as unfinished shells with 5m ceilings, allowing owners to progressively expand from 18m² to 90m² over time. The firm's design philosophy centers on 'Matérialité, Rationalité, Réversibilité' (materiality, rationality, reversibility), emphasizing raw, honest materials, bioclimatic passive design, and reversible construction.
The firm generates revenue through professional architectural fees, typically structured at 8-12% of construction cost, sourced through architectural competitions, public tenders, and direct commissions. Its client base spans French private real estate developers (Eden Promotion, NHOOD, Icade, Adim), social housing providers (Office 64, Domofrance, In Cité), and public institutions (municipalities, Région Nouvelle-Aquitaine), with a mix of large mixed-use urban projects (e.g., €28M Ilôt Counord) and smaller private commissions. The firm is a recognized leader in French contemporary architecture, with prestigious awards including the Équerre d'Argent 2023, Pyramides d'Or 2020, and AJAP 2020, and has been featured in leading international architecture publications including Wallpaper, A+U (Japan), and AMC. A6A is privately held by its three founding partners, with no institutional investment or external shareholders.
