As a typical “tenement palace“ of the Ringstrasse era, Palais Epstein comprised not only the residence of the family of its builder, Gustav Ritter von Epstein, and the offices of the L. Epstein Bank and Wholesale Company, but also contained several apartments and business premises offered for rent.

Class distinctions among the inhabitants of the palace were clearly reflected in the way in which space was allocated both horizontally and vertically: the first floor - the bel étage - provided the Epstein family with a sumptuous living environment, while the rented apartments on the second and third floors were less richly appointed. The servants, in their turn, were accommodated at the rear of the building, in poorly equipped rooms on all floors or in low-ceilinged dwellings on the mezzanine floors.
