L’atelier DEV is a collaborative architecture studio operating at the intersection of disciplines, scales and territories. Based in Brussels, Berlin and Paris, the practice approaches space as both a physical and political matter, exploring how architectural projects can respond to contemporary societal, cultural and urban challenges.
At the core of its work lies a strong expertise in sustainable and circular construction, rooted in a genuine culture of architectural reuse. L’atelier DEV advocates an architecture based on restraint, the valorisation of existing assets, the use of low-impact materials and a commitment to limiting land consumption while maximising the use of available space. Its projects rely on robust, adaptable and repairable structures, designed to last and developed with and for their users.
Bringing together complementary backgrounds in research, professional practice and education, L’atelier DEV considers architecture not only as a discipline of construction but also as a framework for critical reflection and dialogue. The studio employs research-based methodologies and intercultural perspectives shaped by academic work, cultural initiatives and field investigations.
Its practice encompasses architectural and landscape design, urban studies, exhibition design, interior architecture, research and teaching.
