STUDIO D'ARCHITECTURE GALLIOT VANNIER

What STUDIO D'ARCHITECTURE GALLIOT VANNIER does

Studio d'Architecture Galliot Vannier (SAGV) is a French architectural firm founded in 1986 by architects DPLG Jean-François Galliot and Christian Vannier, operating as a Société par actions simplifiée (SAS) and headquartered at 61 Avenue Verdier in Montrouge, France. The firm provides full-service architectural design, urban planning, and landscape design across residential, healthcare, sports, public, and mixed-use programs, with a particular specialization in social and affordable housing, senior residences, student housing, and specialized care facilities for vulnerable populations. SAGV employs Building Information Modeling (BIM) as its core digital design platform, using it for digital modeling, environmental impact evaluation, and to support low-carbon design approaches such as BBCA-certified construction, material reuse, and selective deconstruction.

SAGV's client base is anchored in French public-sector housing operators (including CDC Habitat affiliates, Essonne Habitat, Logis Familial, SEQENS, and Altérité) and private developers (Icade, Groupe Arcade, Coffim, Réside Etudes), with projects acquired primarily through architectural competitions and public procurement tenders. The firm holds a substantial stack of French sustainability credentials (BBCA, RE2020/RE 2025, NF Habitat HQE 6*, BiodiverCity, E+C- Niveau 1, Bâtiment Biosourcé niveau 3) and was awarded the Prix 100 quartiers innovants et écologiques Île-de-France. Active project work spans the Île-de-France region (Montrouge, Choisy-le-Roi, Vitry-sur-Seine, Grigny, Itteville, Bondoufle, Marcoussis) as well as southern France (Ajaccio, Mouans Sartoux, Bénesse-Lès-Dax) and Le Mans in Pays de la Loire.

The firm generates revenue through project-based architectural fees tied to scope, surface area, and complexity, with contracts typically spanning multi-year design and construction phases. With a lean team of approximately 8 professionals including 6 architects and 1 administrative manager, the firm operates as a founder-led boutique practice with an emerging multi-generational succession via founder family members Paul and Benjamin Vannier now on the architectural staff. Marketing is conducted principally through the firm portfolio website, competition participation, and professional network reputation rather than digital advertising channels.
