The Robotron Canteen is understood as a significant example of East German modernism – a building of spatial clarity and collective memory. The proposal treats the existing structure as a resource and reactivates it through precise, minimally invasive interventions. Roof and façades are repaired, non-load-bearing walls removed, and the original openness restored. Two reversible service boxes function as “plug-ins,” integrating essential facilities without altering the historic fabric. A flexible system of lightweight, modular elements structures the interior and enables diverse uses ranging from exhibitions to workshops.
The climate strategy follows a consistent low-tech approach based on thermal zoning, natural ventilation and selective heating of core areas. The aim is cost-efficient, sustainable and climate-resilient transformation grounded in sufficiency and circular construction. Outdoor spaces are activated as climate buffers and areas for public use. A mobile “Mini-Canteen” operates as a circular architectural element and urban catalyst.
The jury praised the respectful handling of the listed structure, the clear orientation toward Lingner-Allee and the flexible floor plans. The low-tech strategy, energy awareness and reuse of materials were positively highlighted. Critical remarks concerned the restrained façade expression, aspects of natural ventilation and the proposed solar air collector. Overall, the project überzeugt through its process-oriented, resource-conscious approach and strong spatial quality.
