The thesis is focused on creating of aggregated items and pricing appreciation of the group works. This thesis deals with in its early life cycle of building works and defines at what stage it is advisable to use the aggregate cost. The following part is aimed at budget in the aggregated prices and creating aggregated prices. In practical part there is methodology designed to compile aggregate price of building construction. The aim of methodology is to propose evaluation process of coherent construction work groups. The proposed methodology will be used to value case study of family house.

For a simplified calculation of the price of work I propose methodology of creating aggregated items, so that to calculate the price of an object wouldn´t take not more than one hour, while the final price would be with the least deviation from the exercise price. The accuracy and performance will be assessed on two objects. Their price will be calculated and based on the proposed methodology.
