Numerous studies have confirmed the importance of blue and green infrastructure in urban areas, as well as the potential of water elements in built-up space and their climatic, ecological, sociological and economic impact. The Bajer lakes in Soblinec settlement in Sesvete form a complex of a total of four lakes interconnected by embankments. With the exception of minor interventions by the local fishing society, the area of the lake has never been completely revitalized or landscaped. In the thesis, the existing features and elements of the space were inventoried and analysed, a survey was conducted with users and visitors, relevant literature was researched on the revitalization of similar brownfield areas and water systems in cities and their impact. The results showed that there is a large unused potential of the area, a lack of public accommodation and sports and recreational facilities, and desire to arrange the area of the lake. Based on the results of the survey and analysis of the space, a project program and a conceptual proposal for the arrangement of the lake were built. The new proposal includes the retention of quality vegetation and habitat quality created by succession, as well as sports and fishing content, along with the introduction of new residential, educational and sports content.
