What Ameller Dubois does

Ameller Dubois & Associés is a French architecture and urban planning firm founded in 1989 by Philippe Ameller and Jacques Dubois, headquartered in Paris (8 Impasse Druinot, 75012) with a secondary office in Nantes established around 2021. The firm provides comprehensive architectural services across six verticals: public buildings (schools, colleges, police stations, fire stations), healthcare facilities (hospitals, EHPADs, wellness centers), housing and residential development, cultural buildings (museums, libraries), transportation infrastructure (airports), and urban planning. Core technical methodology centers on case-by-case environmental performance analysis, bioclimatic design, HQE/BBC/RE2020-certified sustainable construction, and a formalized rehabilitation approach for heritage and existing buildings.

The firm operates as a privately held Société d'architecture with registered capital of €300,300 and 101-250 employees. Revenue is generated through professional services fees on a project basis, with mandates secured predominantly via competitive public procurement (concours) with French government entities, regional councils, departments, municipalities, and institutional clients, supplemented by partnerships with private real estate developers (Linkcity, Eiffage Immobilier, BNP Paribas Immobilier) and international airport operators (Hermes Airports, SMABT). The customer base spans France, Cyprus, the Dominican Republic, and Haiti.

In 2022 the firm completed a leadership succession, onboarding five new-generation associate architects (Cedric Baelde, Florian Dubois, Alexandre Guibourt, Laurence Sou, Stéphane Védrenne) to take over alongside the founders. The firm is recognized internationally through awards including the WAN Awards Silver 2020 for the Ecoquartier Victor Hugo, and has launched a sub-brand, Ba|So (Groupe Ameller Dubois), to broaden its service surface. Marketing is driven primarily by award recognition, professional referrals, and direct institutional relationships rather than traditional channels.
