Creation of impressive entrance space, strict and modern which would be the indirect proof of the status of the organization was one of the main tasks of the project. In this case an atrium is not only a big lobby but also the communication center. Architects had to think up how to connect two separate parts of the building within the 4 floors. For this purpose at the level of the second floor they made a volume mezzanine by means of which bigger and smaller office blocks were connected. The third and fourth floors were connected by means of throwing the powerful two-level bridge over them. Logical continuation of an atrium is the transformed conference hall of the second floor equipped with system of foldaway chairs.
