The aim of the work is to design a residential building in a Viennese Block, which reacts to its neighborhood by using a fractal analysis and can by this means act integrative on the existing urban ensemble. With the help of fractal measurement methods, parameters for the architectural design concept are determined. The hypothesis is stated that with these parameters, which are incorporated, inter alia, into the facade design, a contemporary architectural style can be better integrated into the existing urban ensemble. Therefore, the design result should lead to a facade design, which corresponds to the urban ensemble. In addition, great emphasis is placed on incorporating a forward-thinking, urban-oriented quality in the architectural design, developed from fractal geometry. The main idea of the work is not to distinguish oneself as an architect at the expense of the environment, but to find ways to enrich your own design style with the factor integration to the existing buildings by using fractal methods. As an introduction to the work, the urban ensemble and its impact on surroundings is dealt with. Furthermore, the design, done in this paper, is based on a research on the topic of fractals, their measurement methods and analysis.
