It is typical of stone buildings in the Jugendstil that the wall face is divided up into sections that are treated in different ways, in order to achieve a moulded effect by simple means. In the case of Skolegata 42, the outer walls have been polished smooth in the main part of the house. The ground-wall, corners and details around the windows have a rougher and more rustic polished surface, which is also a slightly darker colour than the main wall. The flat curve, here visible over the windows, is also a Jugendstil characteristic. However, Skolegata 42 lacks typical Jugendstil windows, with their combination of small and large panes.
