 According to plans by architect Theodor Fischer, the foundation stone for a new building with three wings was laid at the corner of Wilhelmstraße/Rheinstraße in 1913.Previously, the banker's mansion Mons had stood there, in which the reception building of Ludwigsbahnhof was housed until 1906.The interior design of the three houses was influenced to a large extent by the three directors and the curators, as there were different needs.
