This used to be an smithy in the 20th century. It has now been torn down and 2 new (1 newly built + 1 completely redone) multi-apartment houses are now constructed at "Auf Den Steinen" numbers 15+16 which use the space where this smithy once was as garden with underground parking. The OSM data does not have any of the new buildings included yet.
