Karolinger Höfe is situated within Düsseldorf’s historic Gründerzeit belt, an inner-city area known for its 19th-century urban development, and to the north it borders the verdant course of the Düssel River, a tributary of the Rhein. This project presented a significant and rare opportunity to reimagine nearly an entire city block. Our approach involved learning from the existing structures, embracing sustainable practices, and incorporating modern enhancements. We followed the urban design of closed perimeter blocks that is characteristic of the surrounding neighborhood, with buildings rising to a maximum of five to six stories. We integrated three openings into the urban fabric, so the development does not simply break off but grows into the surrounding quarter. This interconnected design fosters a density that contributes to a contemporary urban feel. However, we view the green spaces between the buildings as the social glue: three squares with different characters, gardens, open spaces, and playgrounds that bring the neighborhood to life. To ensure that cars do not occupy valuable outdoor space, all parking is underground at Karolinger Höfe. Additionally, we provided 960 bicycle parking spaces to support sustainable transportation options.
