Investigating the development of an urban agglomeration in general primarily leads to the following conclusion: forces affecting space and spatial transformation, which provide room to maneuver, will not be found in the city-center but rather everywhere. This urban development experienced during the last 150 years around all historical city-centers (real as well as artificially constructed), building links between them, and progressing into the central areas is potentially best described in "ZWISCHENSTADT" by Thomas Sieverts. This study elaborates on "Zwischenstadt" as a general phenomenon and illustrates it at a specific Viennese location. Dependencies between different perspectives observed as well as alternative levels of abstraction cannot be easily explained. A suitable architectural concept can, therefore, only be constructed by considering the overall context and less by viewing it as a reaction to the location-specific situation.
