This thesis is concerned with the building of settlements by Franz Schuster (1892-1972) in Vienna's post-war, based on analyses of the settlement "Siemensstraße" (1950-1954) in Floridsdorf and the settlement "Am Schöpfwerk" in Atzgersdorf (1951-1957). After a brief overview of the housing construction during the interwar period, the thesis is going to analyse the housing during post-war period in more detail.The two settlements by Franz Schuster will be compared with other settlement constructions of the same period (housing complex Stadlau by Michel Engelhart / Fritz Judtmann, 1950 and the Per Albin Hansson settlement by Franz Schuster / Eugen Wörle / Friedrich Pangratz / Stephan Simony, 1947-51 and 1954-55).The settlements are examined in terms of location, structure, types of housing, layout, space reference and common spaces. A key question is, to which extent Franz Schuster coined the post-war settlement construction from Vienna. Of particular interests are the implementation of his quick construction programme, his concept of "Duplex apartments" and his interior and furniture designs. Primary sources for this thesis are the drawings of the settlements "Siemensstraße" and "Am Schöpfwerk" also typescripts and manuscripts of Franz Schuster from the archives of the University of Applied Arts and the drawings of the -Baupolizei- MA37.
