Conversion of the former Karstadt building House B into a public center for education, culture and services based on a mixed-use concept at Königstraße 52, 23552 Lübeck. A former retail space (Karstadt Sport) is to be revitalized as an essential part of an innovation process in Lübeck's old town by focusing on education and culture. Demand areas for the four old town grammar schools are to be accommodated, as well as space for the TH-Lübeck, Musikhochschule, University of Lübeck, Lübeck Technical Centre, Open Channel (Radio) and other services are to be created. In the course of the discussion about the future and attractiveness of Lübeck's city centre, in the light of the structural change of city centres in general, accelerated by the pandemic and the associated need for new, innovative concepts for future-proof, sustainable and resilient city centres, the building is to be put to a meaningful subsequent use.
Against the background of the planned mixed-use use, there are challenges, which are particularly evident in the interfaces of the different planning trades. Planning services must be provided much more closely interlinked in this project than would be the case with less urban development sensitive projects.
Thus, the decision was made to tender the planning service as a general planning service, resulting from the considerably increased complexity of this construction task (inner-city environment, technical interlocking, etc.) as well as the large number of stakeholders involved. The user community plays a central role here, as their requirements and needs must be reflected in the named interfaces across disciplines.
The Hanseatic City of Lübeck is also an EEA partner municipality with an award for its high level of commitment to climate protection. With this in mind, the Hanseatic City of Lübeck is striving for EEA Gold status and therefore relies on high efficiency standards for all new buildings and renovation projects. For this building, this means achieving the Efficiency House Standard 55 (according to BEG). This standard is given if the primary energy requirement is 45 percent and the transmission heat loss is 30 percent below that of a new GEG building (reference building according to GEG of 08.08.2020).
In addition, additional goals are planned for this project, oriented towards the federal program "Rehabilitation of municipal facilities in the fields of sports, youth and culture", which are as follows:
- Sustainable material extraction: climate- and resource-saving construction
- On-site natural hazards: Assessment of on-site natural hazards and taking appropriate adaptation measures in terms of resilience
- Implementation of comprehensive accessibility measures: involvement of the person responsible for the interests of persons with disabilities
For the development of an innovative and cross-use space requirement concept, the city of Lübeck is working with a team of project developers (FAR, Baupiloten and Metrum) in the form of phase 0 until spring 2024. The aforementioned offices are not excluded from the proceedings. In order to ensure equal opportunities for all participating offices, existing documents will be made available with the notice as well as other documents, including Phase 0 results, with a call for proposals. The documents will be published via subreport. This serves to ensure the equivalence of the conditions of participation and to create a solid basis for the processing of the solution outline/planning task in the second stage of the procedure.
The VgV procedure and the project management for the project are supported by Bureau Veritas Construction Services GmbH.
