Abstract. In the era of progressive technological and social development, housing environment should respond to actual demands of modern society, with the idea of flexibility and adaptability as the key parameters of sustainable living. Application of the flexible elements in the interior provides a variety of spatial interpretations of the residential unit that can be determined by an architect or by users, depending on the applied design concept. The degree of achieved spatial flexibility will depend on the degree of independence of moveable elements within the unchanging structure of the apartment. Appropriate selection and analysis of the certain number of projects and realizations in the field of flexible housing, points to the diversity of motives of flexible elements application and considers the impact of applied design approach on the interpretation of residential environment. Different social, political and economic circumstances in which the individual examples emerged are also taken into consideration.Key words: housing interior, flexible elements, open plan
