Slovenian territory is characterized by diverse geological and geomorphological structure and tectonic activity. In designing and construction of objects it is therefore necessary to pay special attention to geologically caused risk factors, namely landslides, karst collapses, flooding of groundwater and surface water, tectonic zones, and soft and very compressible ground. In designing of large infrastructure objects, geological and geotechnical researches are an important integral part of planning of work in early stages of design and during construction. In designing and construction of individual houses and local traffic roads, geological and geotechnical researches are often overlooked either due to ignorance and short-sightedness of investors or savings in short term. Therefore, it is not coincidence that from year to year we face enormous damage on residential objects caused by landslides, floods, and uneven subsiding. An important role is also played by the fact that with constructions we increasingly interfere with the areas that our ancestries avoided, and also by more frequent weather extremes. In the graduation thesis, I presented the most common geologically caused risk factors in Slovenia, and their consequences on individual residential objects. From the geotechnical perspective I analysed and compared two locations for construction of residential object in the vicinity of Brezovica. Advantages and disadvantages of both locations for construction are presented.
