This thesis deals with structures in industrial building construction. Examined was how structures, walls, columns, slabs and other elements with weight-bearing function in the last 100 years have changed with regard to design and materials used. The aim of this study is to find out to what degree industrial buildings can be brought to a new use. At the basis of this study, the former sugar factory in Siegendorf was taken as an example. This example shows how use flexible industrial buildings are, which buildings are suitable for reuse and which are not, and what steps need to be taken to reuse and maintain the buildings. The result of the study shows that it is much more difficult to reorganize a building, whose original purpose was more special than usual ones. So, in storage buildings, homes and offices, a high degree of reuse can be determined. For very special buildings, such as production buildings, the degree of reuse drops significantly. In the studied industrial complex in Siegendorf was found out, that 41,12% of the available area can be brought to a new use without making special interventions in existing support structures.
