Analyzed data have been collected during a field research in accordance with the current administrative regional division, and they represent a basis for definition of regional typology of individual housing units. Characteristic types of objects of each region’s typology have been further analyzed. Upon these analyses regional characteristics of individual housing units regarding applied construction types, building technologies and materials have been defined and presented. Key words: individual housing units, regional characteristics, typology, building technology. economic, political and cultural aspects, one can windows, volumetric characteristics of the 1 INTRODUCTION examine the connections of architecture of the buildings, and the percentage of window surfaces The basis for the research presented in this region’s individual housing units, its applied on the facades.
