The aim of the study was to document the changes in residential construction in Vienna using examples from the last 20 years. The focus of the analysis is on the changes since the introduction of property developer competitions in 1995, since which there has been a general increase in the quality of subsidized housing. In this context, the influence of the amendment to the building regulations in 1996, which resulted in some changes with regard to the necessary spaces within the apartment, is also assessed. 32 projects were selected and analyzed according to the same criteria.
