There were several workshops in the house, a locksmith's, a painter's and a cardboard factory, and a tavern and a shop towards the street.
The house also provided emergency accommodation and food for Jewish refugees from Galicia and Bukovina, who did not return to the new nation-states established on the territory of these former Austro-Hungarian provinces after the First World War. Poland, Romania and Hungary, unlike the old empire, introduced anti-Jewish regulations restricting educational opportunities.
Part of the ground floor of the house was converted into production workshops and a shop for the Sigma-Radio company of the engineer Szatmáry.
