The authors of the study used statistical from statista.com concerning the number of LEED certified projects during 2018 to 2021. Statistical indicators of countries is used to select houses for research, an assessment of a group of experts of photo-interview methods is used to determine the main trends in visual environmental design. <b>Results:</b> It was possible to systematize the world experience in designing private homes using an ecological approach. They categorized the basic principles of visualization of functional-planning, technological and artistic-esthetic solutions in the interior design of a private residential building; compliance with appropriate esthetics; functional design solutions of the interior space, modularity, compactness, responsible and rational architecture; and interior design, preferably with the possibility of moving housing to another place in case of forced relocation. <b>Conclusions:</b> The results obtained can be used in the framework of theoretical and practical design of private residential buildings.
