Abstract
This paper presents the methodology and results of the research aimed to identify the current and potential functions of open public spaces in post-Soviet modernist urban districts in the context of sustainable urban development. The research is based on the sociotope mapping methodology facilitating the identification and interpretation of functional characteristics of urban open public spaces. The data for this research has been collected in three selected pilot multi-apartment modernistic districts of Kaunas city (Lithuania) using two sociological research tools – site observation protocols and user questionnaires. The research results show the need for actors involved in planning and (re)development of modernistic districts to incorporate a larger diversity of space elements enabling different local area users (individuals, families, organizations) to use and experience more natural, social, economic and other values available locally at different time (year, day) periods.
