The last major survey on housing quality, carried out in 2005, showed that Slovenia is bringing up the rear where European housing standards are concerned. An average dwelling in Slovenia has an area of 78.6 m², which puts it in last place. Even today, 56.4 % of residential buildings have only one to four upper floors, and only 12.6% have more than five floors. This is reflected in the structure of our towns, and the trend of growing sub-urbanisation implies their further spreading.
 The survey was carried out in 2005 by Faculty of Human Sciences of University of Ljubljana. The results were presented in: Mandič, S., Cirman, A.: Housing in Slovenia 2005, Faculty of Human Sciences, Ljubljana (2006)
