Purpose: Parameter identification of the quality improvement of engineering redevelopment; identification of the main parameters of improvement; theoretical aspects of landscaping.   Methodology: Terminological and semantic analysis; theoretical comparative analysis.   Originality: Identification of comfortable environment parameters in terms of engineering redevelopment.   Research findings: The territory improvement is important for creating the environmental space, the quality environment is characterized by the improvement components such as visual perception, durability of elements, safety, presence of vital objects with regard to the needs of citizens. The quality environment is affected by spatial microparameters and engineering support parameters.   Practical implications: The results can be used for assessing the quality of life, since engineering redevelopment creates conditions for achieving the vital environment.
