During its first 15 years, Atelier Aconcept has been able to hone its methods while relying on its good humour to encourage the creativity of its multidisciplinary team. Thirty collaborators with complementary profiles (architects, urban planners, economists, graphic designers) compare their experiences for a decompartmentalised approach and the emergence of innovative urban projects. What do they have in common? To feed off the latest trends and to constantly challenge themselves, in particular by mastering new technologies such as BIM.
