Over the past two decades, the Slovenian real estate market has experienced major changes. Increasing
purchasing power and customer needs lead to an extensive increase in construction. The described
phenomenon may lead to poor construction quality and in this respect, Slovenia was no exception.
The master thesis addresses the quality of housing units from the point of view of potential customers
who want to know what to expect for their money. In this context, first, the properties of residential
units that represent their quality, and are therefore requested by the potential buyers, are identified. To
determine the residential unit quality level, a multicriteria model is developed. The model consists of
hierarchically distributed criteria (parameters) in four levels. At the first level, five key criteria are
located: location, architecture, living comfort, technical quality and energy efficiency. Location
conveys the impact of the surroundings upon the residential unit, and as it can not be substantially
modified, it is considered as a type of real estate potential. Architecture as an added value to the
building is also a prerequisite for comfortable and quality living. Technical quality, living comfort and
energy efficiency are building matter, and their quality is recognized through the technological
progress. By using the developed multicriteria model for the residential unit under consideration, an
overall assessment based on point scale that reflects the level of achieved properties of the unit is
determined. The results obtained by the proposed methodology are comparable irrespectable of the
residential unit type. The point scale ranges from 1, where the property under consideration conforms
to the valid Slovenian legislature, to the upper limit, 5, where the grade is justified on the basis of the
research presented in this work. The applicability of the proposed model is presented by analysing two
selected cases of residential units in multi-apartment building and a parametric study.
In the first case, the residential unit is located in urban environment, while in the second, it is located
in rural area in the vicinity of a Ljubljana city. The results show that the overall grade of the first
residential unit is slightly higher, but taking into the account the price-performance relationship, the
second case is given priority.
