Without falling into a specialization that might narrow architecture down to a routine, our firm developed over time its expertise in six broad areas. Offices and business premises have been our primary activity, with the development of Eurotunnel headquarters in Paris, and the design of Motorcycle Center in Trappes. Then, in 1990, Philippe Ameller and Jacques Dubois - guests and winners of their first common public competition (a kindergarten) - initiated more than two decades of designing educational buildings, from early childhood to university. Chosen by the Assistance Publique-Hôpitaux de Paris for the restructuring of the geriatric hospital René-Muret, the firm addressed the health sector, which is now an important skill of its architects. Police and fire stations acquainted us with the very specific practice of safety facilities. The range of our regular activities encompasses a thousand apartments in various regions, from the Atlantic Coast to the French Alps and the heart of Paris. In addition, the design of culture and tourism facilities in France and abroad is our most recent growth axis.
