Um Bock School - Retrofitting with Purpose and Participation

The retrofit and extension of the Um Bock School in Differdange preserves far more than a building — it preserves identity, memory, and community connection. Originally built in the 1950s, the school’s concrete structure and interior brick walls were consciously retained, maintaining their material authenticity and aged patina. Instead of replacing damaged areas with new materials, the project embraced an unconventional, community-driven approach. Where bricks were missing or broken, a participatory artistic process was initiated. In collaboration with local artists, children — the future users of the school — were invited to design their own bricks during workshops held on site. These colorful, imaginative pieces were then integrated directly into the interior walls, becoming an integral part of the architecture. This act gave each child a sense of pride, authorship, and legacy — their creativity now literally embedded into the school they will inhabit. Architecturally, the project moves away from a traditional corridor layout. A series of offset, interlocking volumes generate generous, light-filled circulation spaces, which double as informal social and learning zones. Square classrooms allow for maximum flexibility, supporting evolving pedagogies and inclusive educational practices. The extension introduces new functions — including a sports hall, climbing wall, and dance space — that open the school to the wider community. Through careful conservation, social inclusion, and participatory design, Um Bock demonstrates how retrofit can regenerate not only architecture, but also collective belonging.
