Atelier Novembre Architecture

What Atelier Novembre Architecture does

Atelier Novembre is a Paris-based architecture firm founded in 1989 by Marc Iseppi and Jacques Pajot, specializing in public cultural, educational, and infrastructure buildings across France. The firm employs approximately 27–30 staff, including three associate architects (Natacha Fricout, Marine Guitton, and Charles-Elie Mathais) integrated into the partnership in 2023. Its portfolio spans heritage rehabilitation of Monument Historique-classified buildings (Musée Dobrée, Inguimbertine, Quadrilatère des Archives for the Ministry of Culture), cultural and educational facilities (CentQuatre, Lycée international de Palaiseau, Conservatoire de Pantin), urban master planning (Quartier du Palais de Poitiers), and transport infrastructure, where the firm holds a unique position as the only architecture practice designing 5 Grand Paris Express metro stations across Lines 15, 17, and 18.

The firm operates an exclusively B2G business model, generating revenue through project-based design fees on commissions won via French public procurement competitions (concours) and direct government mandates. Project values range from €8.5M (Cité administrative Briançon) to €70M (CentQuatre Paris 19e), with design fees typically a percentage of construction value. Distribution is single-country (France) across 10+ regions, with no retail or self-serve channels. GTM is sales-led, driven by competition participation, Bpifrance accelerator selection (December 2025), and recurring engineering partnerships (Oteis, ARTELIA, Benthem Crouwel Architects, Bouygues IRIS groupement). Differentiation rests on three decades of heritage rehabilitation expertise, sustainability credentials (BEPOS Effinergie 2017, E+C- standards, low-carbon concrete, biosourced materials), and a strong media profile (Venice Biennale 2018, Eiffel de l'Architecture 2025, AMC 100 Bâtiments de l'Année).
