Construction has been one of key activities in Kostak Group for more than 60 years. In cooperation with several of our subsidiaries we provide services that include project development, architectural and technological design, construction and reconstruction, market sale and maintenance.

We grow our success on our own knowledge, development and experience as well on participating in the most demanding construction projects, such as the construction of hydroelectric power stations, distribution networks, state roads and residential facilities.
