This work proposes a theoretical and practical study of environmental design. The aesthetic image in design is created by involving several special mechanisms that ensure the integrity of the design concept. The study highlights the most important principles of plastic and semantic realization, following the clear and concise presentation of the image. In this process, the most responsible and important issue addressed in design is identified - aesthetic formulation. A special role in the beautiful realization of the design project, is assumed by the coloristic effect, which manifests various actions in relation to human psychology. Following them, the basic criteria in the harmonious realization of the artistic image are identified, taking into account some legalities and norms of aesthetic beauty. The new practices of environmental design include the realization of ecological projects, smart house projects, open space projects and of course various stylistic achievements, of which the most requested today is the minimalist style. Overall, environmental design is an effective means of shaping and recreating the human environment.
