The aim of the study was to transfer the existing building into contemporary architecture with a few targeted interventions and additions. In doing so, the characteristic features of the ensemble are preserved and supplemented with new elements. The concept includes the complete design up to the interior of the building. Based on an analysis of customer requirements for the bank of the future, it will be completely reorganized and optimally adapted to work processes. A modern working environment with New Work elements replaces the previously classic branch design.
