What GPAA Architectures does

GPAA Architectures is a French architecture firm founded in 1994 and headquartered in Nantes, Pays de la Loire, with a secondary office in Paris. The firm operates as a SARL with approximately 21 employees and €150,000 in share capital. Governance rests with four managing partners — Renaud Tudoret, Thierry Méchineau, Delphine Coriou, and Sylvain Lerays — succeeding the founder Gaëlle Pénneau. The practice has delivered more than 60 projects across France.

The firm specializes in public-sector architecture, with project typologies spanning educational facilities, healthcare buildings, sports complexes, cultural venues, and social housing. Technical emphasis is on wood construction, biosourced materials, and HQE (Haute Qualité Environnementale) environmental standards. Notable commissions include the Paris Dauphine University Campus (project budget reported at approximately €104M), the Roland Garros Tenniseum renovation, and the École de Design Nantes Atlantique, which was preselected for Archdaily's Building of the Year 2024. The firm also pursues collaborative models with international architects, including Cruz y Ortiz and Joao Luis Carrilho da Graça, on larger concours.

Revenue mechanics are derived from public-sector architectural commissions secured through competitive tenders (concours). The firm serves a client base of municipalities, hospitals, universities, and government agencies across France, with active project sites including Nantes, Paris, Marseille, and Montpellier. Architect fees are tied to project budgets that range from modest civic commissions to flagship institutional projects, yielding a fee revenue profile consistent with a small-to-mid-sized French architecture practice.
