Kalle Neukoelln Department Store Revitalization / Max Dudler

The "Kalle Neukölln" project revitalizes the former Quelle department store on Karl-Marx-Straße in Berlin. This large-scale building, including a 1970s parking garage, is a key Neukölln landmark. Berlin-based developer MREI is transforming the site into a creative hub, while Max Dudler is redesigning the façades. The concept follows the principle of "rethinking instead of demolishing," preserving the building's embodied energy. The result is a contemporary space for work, culture, and social interaction—serving as a model for the sustainable repurposing of retail properties.
