The presence of a large number of undeveloped areas within the city - now inactive enterprises - creates a negative impact on the urban environment. Since these territories are depressed spaces, the design of new residential areas with characteristic high-rise buildings seems to be a logical path for the development of the city. However, uncontrolled urbanization and dense multi-storey buildings represent a fundamental change in the human environment. The consequences of this approach lead to a deterioration in the air exchange of areas and contributes to the formation of “heat islands” that affect air pollution. This contributes to the deterioration of the environmental and social situation and the emergence of a negative perception of the environment among the population. The worsening of this problem may cause a deterioration in the social climate in large cities. The article analyzes the impact of dense high-rise buildings on the environment located on the territory of non-operating enterprises. Methods for solving this problem are indicated. The results of field observations and studies of the interhouse space are presented, on the basis of which the role of convective flows of thermal origin in the air exchange of urban space is revealed. A comparative analysis of projects for the development of the territory of a former house-building plant with complexes for various functional purposes is presented.
