This building block numbers 1-5 between Bartensteingasse, Doblhoffgasse, Auerspergstraße and Schmerlingplatz is the largest of its kind in the Rathausviertel. It was built in 1873-1874 by Josef Hudetz and Moritz Hinträger on an irregular ground plan. Striking features of the building are the building blocks on the upper floors, atlases on the ground floor of the Risalite, hermene in the attic storey, column portals and corner trusses with pyramid roof trusses. The entrances are designed in different ways, such as spandrels, friezes or stucco ceilings.
