The topic of this thesis is small garden associations in Vienna. Small gardens (also known as allotment gardens or community gardens) are a worldwide phenomenon, but only the city of Vienna took the risk of officially permitting residential use throughout the full year. The ramifications of this decision (both positive and negative) are thus not only of interest for the future development of the city of Vienna, but for all small garden associ- ations in urban areas worldwide. To this, the present thesis contains a theoretical part that deals with the history of small gardens, the laws concerning small gardens, as well as the international situation of small gardens. Over the years, they have provided the city of Vienna with many useful functions: From naturopathic gardens to cultivable land for fruit and vegetables during war time, to flower gardens in post war times, to today´s main function, the private lawn. The laws governing the construction in allotted parcels depend, of course, on the era, and are particularly important nowadays (because of the full-year residency). Finally, there is a brief subsection about the international development of small gardens, which I could track as far as Japan. In the practical part of the thesis, I investigated the small garden association "Wasserwiese" in Vienna. This section contains a photographical documentary, empirical data, and their analysis. The main conclusion I am drawing is that, because of a missing urban development concept, the small gardens have changed into uncontrolled housing development areas that do not share much with the original concept of a small garden anymore. The final section is a project work, in which an urban development concept was devised. This concept is based on the conclusions from the practical part and aims to create a new form of small garden area at the location "Wasserwiese";. This new form is designed with the intent of synergy between the increase in population density, caused by full-year residency, and the positive aspects of small gardens. To give an impression of how the new structures could look like in the future, I did a design study on three of them.
