On 8 October 2007, the European Central Bank (ECB) presented the outcome of the detailed planning phase for its new premises. The design was submitted to the relevant authorities of the City of Frankfurt for planning permission. On 22 October of the same year, the City of Frankfurt gave the go-ahead to start the preliminary construction work in the first quarter of 2008.
On 6 May 2008, Petra Roth, Lord Mayor of the City of Frankfurt am Main, handed over the building permit for the entire new premises project to Jean-Claude Trichet, President of the European Central Bank.
Among other things, the preliminary construction work included the demolition of the two annexe buildings to the east and west of the Grossmarkthalle and the construction of the pile foundations
Analyses on original building elements and materials of the Grossmarkthalle were also carried out in order to develop suitable restoration methods. The overall concept for the interior, including the materials and surfaces, was defined, and various installations were built in order to test both the functionality and quality of the materials chosen.
