DSA is an architecture workshop based in Lille and created in 2003, with around a hundred projects in all fields: public facilities (school, sports, cultural...), technical, tertiary, individual or collective housing, outdoor facilities, furniture, signage. The workshop works on projects that are rooted in their local context. These small facilities contribute to the sustainable transformation of the territory. The issues raised by the workshop are multiple and all raise the same question: how to integrate contemporary architecture into our territory?
