Rapidly increasing population, societal change, and increasing development and technological progress create new requirements for urban development. The term ‘Quartier or ‘neighbourhood is often chosen as an answer to the resulting challenges. Quartier has gained popularity in the recent years and the term is now often associated with ‚socially sustainable and ‚inclusive‘. On the one hand, this thesis deals with the theoretical foundation of this concept and on the other hand analyzes existing Quartiere. With the help of a matrix which was developed for this purpose, three Quartiere are evaluated. In order to provide a glimpse into the future, social and technological change are discussed and tendencies of future development, with which a Quartier also has to deal with, are shown. Moreover, the perception of a new urban area as a Quartier is examined in this thesis. A part of the 44ha large urban development area of the ‚Nordwestbahnhof‘ in Vienna, a former freight station, is used as a test field. Its prime location and well developed accessibility are challenged by connecting the area to existing neighbourhoods as well as to parts of the district currently separated by the former station. The findings of the theoretical discussion, the evaluation of existing Quartiere, as well as the analysis of the area of the Nordwestbahnhof result in a ‚learning‘ ruleset. These rules, which are constantly improving through the ability to ‚learn‘, are responsible for the performance of urban structures. Translated into a conceptual design, the Quartier represents a viable level of action for social urban development and integration into the existing environment and neighbourhood structure of the Nordwestbahnhof.
