Ateliers A+. Founded in Montpellier in 1988 by Denis Bedeau (1954 - 2007) and Philippe Bonon (1956), the firm initially emerged as BBA and was consolidated in 1995 as A+Architecture SARL. Over time, other partners such as Philippe Cervantes, Gilles Gal, and Christophe Aubailly joined the team, contributing to the firm’s expansion and diversification. In 2024, the merger of A+Architecture with Arteba, L’Echo, and Celsius Environnement gave rise to Ateliers A+, a name intended to reflect the firm’s multidisciplinary approach and the evolution of contemporary architecture.
With offices in Montpellier, Toulouse, Nîmes, and Paris, Ateliers A+ develops projects both within and beyond France, covering a wide range of typologies in the fields of culture, tertiary sector, housing, healthcare, and urban planning. Its team of over 100 professionals combines knowledge, experience, and enthusiasm to collaboratively design projects at all scales, integrating eight disciplines: architecture, urban planning, landscape, environment, design, engineering, economics, and management.
The firm has carried out numerous projects that contribute to the heritage of Montpellier and its surroundings, including the Arena, the Altrad Rugby Stadium, the Jean-Claude Carrière Theatre at Domaine d’O, the urban redevelopment of Port Marianne, the Saint-Jean Clinic, the Liner office building, and the expansion of Montpellier Airport. However, the majority of its activity takes place outside the region, with notable projects such as the redefinition of the entrance to Cap d’Agde, the construction of a casino and convention center (Hérault), the Ada Lovelace College in Nîmes (Gard), a call center for emergency services and firefighters in Nîmes-Garons (Gard), the expansion of a hospital in Villefranche-sur-Saône (Rhône), nursing homes in Pomarez, Gimont, and Lantosque, a housing and commercial complex in Villeneuve-Tolosane, student residences for the CROUS in Aix-en-Provence and Marseille, and a cultural events center in Mende (Lozère).
