It was found out that there are some over 200 year old wooden houses in Slovenia, mainly built from wood. 100 years ago our houses were exclusively made of wood in the countryside. These days there are only 2 % of wooden houses in Slovenia. The consumption of wood as a building material diminishes in regard to the usage of other building materials. By questioning the Slovenian companies producing wood for building purposes we found out the reasons for this situation, why they do not use more wood in building industry. We also found out that buyers so as investors do not know wood as a building material well enough, they do not know its positive qualities. This situation could be changed by active propaganda and writing various professional articles. In this way whole Slovenian wood economy could also be influenced.
