A short-term extension of the existing school became necessary due to the restructuring of the European Central Bank. The new building could only be approved as a temporary structure and was realised within a period of 17 months, from the planning request to the start of use. The timeframe of the public building project was made possible by an innovative contracting model with functional tendering. 400 pupils are taught here in preschool and primary school, each in their own zone. The design already provided for the extension of the primary school on the northern side, which was realised in the meantime.
