In the next few decades a great need for additional homes will be given in Vienna as a result of above-average population growth, the trend towards small households and the desire for more proportionate space. Although the demand on the Viennese housing market already exceeds supply, requirements and subjective expectations of the customers increase and affect more and more the architectural concept and the economic success of a project. Therefore, the sustainable use of residential buildings requires the analysis of criteria in line with the market and demand previous to the design, in order to ensure a specific focus on the needs of future users. Accordingly, in addition to the design of an urban housing project, the corresponding basis for decision for the achievement of a sustainable project design are brought up for discussion in this diploma thesis. In a preceding feasibility study, the comprehensive analysis of location, market, use concept and competitive projects forms a basis for the following design and, together with the draft idea, allows for both competitiveness and uniqueness of the housing project.
