The theme of this thesis is devoted to Sokolski dom in Ljubljana and its renewal, which falls under the secular architectural heritage. The selected restoration works do not intervene with the structure of the building, so a building permit is not neede. We want to refurbish the appearance of a building and extend its lifetime. Modernization, such as the installation of new thermal insulation composite windows, must be carried out with scrutiny and not at the expense of the destruction of the original architectural design. This means that we take the suggested implemented measures into conjoined account with the law of protection of cultural heritage. ZVKDS issues the cultural renovation conditions and then a cultural consensus for proposed renovation work. The measures selected for the renovation works are accurately described, in particular facade work, carpentry and roofing are the most demanding and consequently represent the greatest expense. These works require a lot of precision and are time-consuming, mainly because the use of modern construction practices is limited in dealing with cultural heritage. Although the inventory part contains a large array of possible works, older buildings still present a large likelihood of unforeseen costs. The result is a recapitulation of the census and represents the basis for further decisions on the extent of recovery of the hall Tabor.
