The ideas of humanism, which have been present in Europe for more than five centuries, today face a number of still unresolved problems. The most important of them are the problems of structuring the population and personalising the architectural environment of housing estates. Different groups of residents try to reconcile the built environment with their own priorities, requirements as well as artistic and aesthetic tastes in processes of self-organisation and harmonious, i.e. sustainable, development of the housing estates. In some national and international studies on contemporary architecture and urbanism, attention was paid to solving the problems of harmonising the built environment. This led to creating projects, forecasts and utopias. Less attention was paid to the socio-psychological, mental, spatio-temporal, artistic and aesthetic issues of urban communities and the conditions for their harmonious coexistence. The authors of this article seek to fill this gap in their own research on urban synergetics and the theory of harmonisation of the architectural environment, the results of which can be combined within the concept of harmonisation of the urban environment. This concept combines different models for shaping a comfortable and aesthetic living environment, taking into account the mentality and psychology of different groups of residents. New ideas about the personalisation of urban communities, the structuring of the environment and the cyclical nature of social development formed the basis for the unification of the models developed. The proposed concept can provide a theoretical and methodological basis for further research, as well as a basis for implementing the developed models into the practice of harmonising the architectural environment of the housing estates.
