The thesis deals with the issue of Viennese urban development, with the local restriction to the area between "Erdberger Mais" and "Simmeringer Haide". The city of Vienna is currently facing the opportunities and risks of a rapidly growing metropolitan area. The demand for affordable housing is very high, the individual traffic approaches a problematic size as well as the need for high - quality open spaces is increasing. Moreover, regional issues need to be discussed within the urban context. The city as a built agglomeration cannot exist without ist surroundings. Both, energy required for electricity and heating, as well as basic needs such as food and water mostly need to be imported. Additionally, cities also have to cope with problems such as global warming, the shift from fabrication to services, outsourcing to the virtual space and many more. All these issues have an impact on the cities-future development. In this particular area, southeast of the former city walls, development has been slowly accelerated only during Vienna's "Gründerzeit"-period. Industrialization and the rise of the bourgeois led to building on former agricultural areas, which still exist today - yet in a transformed way, though. The planned World Expo which was supposed to take place in 1995 and the following extension of the U3 to Simmering, as well as the renovation and conversion of the Gasometer lead to the site's first major changes. In recent years, development has been accelerated mostly by the increasing number of population. This thesis should offer a variety of strategies, which should mark a contribution to current urban discourses.
