With an interdisciplinary planning team of architects, engineers, and real-estate economists, and other experts, SSP AG have found new and innovative solutions afor each project in cooperative collaboration. The resulting concepts are characterized by successful identification, high efficiency and good design. In 2013, after a Europe-wide tendering procedure, SSP AG was commissioned with the overall planning of renovation and construction of extensions and new buildings for the Fritz-Henßler-Berufskolleg in Dortmund. Built in 1908 by the municipal building councillor Friedrich Kullrich, the listed building complex of a former arts-and-crafts and craftsmen school in the Dortmund city centre was in great need of renovation. The task was to satisfy a fixed spatial programme taking into account the building fabric worthy of preservation, both in the existing building stock and through extensions and new buildings. The extension by two building blocks in a strict functional design language and with clearly structured façades allows for an exciting and yet harmonious combination of old and new. Through a sensitive »carry on building« of the existing building stock, a successful new interpretation of the existing fabric was created.
