Abstract
Friedensreich Hundertwasser is one of the participants in the process of transforming the original modernist postulates into a more flexible, humane and open system of rational architectural thinking. His objects, including architectural ones, look like a challenge to rationalism, show a new form of creativity in which the ecological (natural) aspect is a priority. At the present stage, architectural solutions aimed at improving the environmental friendliness of residential complexes are of key importance for the formation of the concept of sustainable urban development. Thus, the analysis of the works of F. Hundertwasser, will contribute to the transformation of the applied methods of designing residential structures.
