What tg·a does
tg·a (Tubiana Gaussuin Architectes) is a Paris-based boutique architecture firm founded in 2023 by Martin Tubiana and Bérénice Gaussuin, both 2011 graduates of the École Spéciale d'Architecture. The practice offers a consolidated suite of architectural services spanning heritage diagnosis, historical monument restoration, interior architecture, scenography, cultural-equipment design, and architectural synthesis for complex multi-stakeholder projects. Its service portfolio draws on Gaussuin’s heritage specialization (doctoral thesis in architecture, training at École de Chaillot, ten years practicing with heritage architect Jean-Paul Mauduit) and Tubiana’s prior direction of Bunker Palace, where he led cultural-facility commissions including Centre Pompidou, Maison de la Radio, the Paris Conservatoire, and the Lausanne Olympic Museum.
Revenue is generated on a project-based professional-services model, with fees negotiated per engagement based on scope, complexity, and client type. The go-to-market is enterprise field sales driven by portfolio reputation, direct relationships with cultural institutions and public authorities, and competitive participation in public tenders. Two offices (Paris 75010 headquarters at 52 rue Bichat and a secondary site in Hyères 83400) support a French operational core, with a first international engagement documented in Vilnius, Lithuania. Select clients include Centre Pompidou (CNAC/OPPIC), Radio France, Ville de Paris, Conservatoire National Supérieur de Musique et de Danse de Paris, Paris 2024, Musée des Arts Décoratifs, Ville de Chennevières-sur-Marne, Bénédictines Notre-Dame du Calvaire, Morabito SA, Emeis, and Ritualas Funeral Home.
The firm has no external funding, operates as an equal partnership between the two co-founders, and staffs roughly five employees in addition to the founders. Delivery is structured around consortia with engineering partners (EGIS Batiment, Elioth, WSP, Cle Millet, AcoustB) and design collaborators (Domino Architects, Scenarchie), with the firm typically serving as architect of record or associate architect rather than lead consortium manager on the largest mandates. No software product, proprietary technology platform, or AI/ML capability is present in the offering.
