The façade consists of common plaster with painting, new windows were installed.
The new building has four underground and seven aboveground floors and was constructed in the inner courtyard of the old building. On the underground floors there are 100 parking spaces. For the construction of these floors, the technology of cast-in-situ ferro-concrete skeleton was applied. On the aboveground floors there is a steel structure with concrete finish on the in-situ concrete ceilings and parapets. The first floor of the new building passes across two floors of the old building, thus forming an atrium. The southern façade (the courtyard part) is glazed with glass plates of various colours. To interconnect the floors, three staircases and two personal elevators were installed. Both buildings are interconnected in such a way as
to enable access to both buildings from each floor.
