This diploma thesis focuses on the issue of unused urban land within the settlements. The unused urban land is here defined as building land within cities that remains unused while the cities expand outwards – often without a proper plan. In the beginning of the thesis, characteristics of urban settlements in Slovenia, the living habits of Slovenian people and some of the reasons for the current state are described. Here, dispersed settlements, dispersed construction and illegal construction concepts in Slovenia are introduced. Furthermore, the basic procedures of urban planning in Slovenia are presented, with the emphasis on local (municipality level) planning. The concepts of land use, urban land and urban development planning are presented, followed by an overview of relevant legislation and certain instruments guiding land use and spatial development in general. In the second part of the thesis, the results of unsued urban land analysis which has been conducted for the case of three Slovene municipalities – Maribor, Hoče-Slivnica and Rače-Fram, are presented. The analysis was conducted in the GIS environment, based on land use data and the Building Cadastre data. Based on these results conclusions are given, which are further the base for discussion on current state, reasons and possible solutions for the presented topic
