Happiness is beeing broadly discussed in many scientific branches. Philosophy, neurobiology, sociology, theology,... -all have ideas about what makes people happy or at least unhappy. In a time where even politicians begin to differentiate between economic progressand the well-being of the population the question arises, what ideas, what thoughts or approaches could be translated into architecture and into the tools of urban planning. The thesis is concerned with the increase of the grossdomestichappiness in the Felberstraßein Rudolfsheim-Fünfhaus, the 15th district of Vienna. Compared to other districts, Rudolfsheim-Fünfhaus currently is ranked last in many aspects. Based on the ideas from the various sciences on the topic of happiness, and the increasingly important political happiness indicators, urbanistic happiness indicators are introduced. These urbanistic happiness indicators are then examined through interviews, media research and examination of the Felberstraße and its surroundings. Finally, the design responds to selected deficient urbanistic happiness indicators. The proposed measures aim to improve the quality of urban space for people living and working in the area, thus increase the grossdomestichappiness in the Felberstraße.
