The building of the "Badische Kommunale Landesbank" -listed for preservation - was to be expanded and augmented by social facilities. The expansion forms an axial continuation of the old palatial building and supplements the marginal block development in the Augusta grounds. Distinct features of the design are the levels which were to be adopted from the existing building, the storey height of 3.38 m allowing little space for carcass construction, air conditioning and electrical double floor.
