In a report to the Budget Committee of the German Bundestag, the Court of Auditors specifically opposes the realisation of the planned construction project. This envisages a 3,300 square metre museum building with 2,500 square metres of permanent exhibition space and 800 square metres of special exhibition space. Together with the "Peking" and the existing Hamburg Harbour Museum in the Hansa Harbour, the ensemble would serve as a German Harbour Museum the status of a national museum.
The federal government had therefore already approved funds totalling 120 million euros in 2015 to fully finance both the renovation of the "Peking" and the construction of the museum building. While the windjammer could actually be completed at the Peters shipyard in Wewelsfleth on the Stör in 2020, the general rise in construction and energy costs is now threatening to thwart the land-based part of the project: According to the Federal Audit Office, the financial requirements could increase compared to the original planning to such an extent that there would be a funding gap of an estimated 100 million euros.
The responsible Hamburg cultural authority also assumes that additional costs will be required, but emphasises that the plans had already been adjusted to the cost explosion in the construction sector before the Federal Audit Office's report. Discussions are currently being held with the Senate of the Free and Hanseatic City of Hamburg regarding cost sharing. The Hamburg Historical Museums Foundation, which will be responsible for operating the museum, expects the German Harbour Museum to open in 2029.
