The conceptual design of the office building is a part of the urban design of the IT park located on Gacka Street in Osijek. The interactive green area, along with public and social facilities that contain three volumes and three focus zones, leads to the main representative entrance located in the east and therefore attracts visitors to the complex. Two secondary communication routes pass through the ground floor of the building creating gaps between three seemingly independent volumes by passing through all the floors of the lamella. The positions of the bridges alternate within each floor, therefore allowing users to undergo a unique experience of the inner hall space each time. Flexibility, openness, and spaciousness of the working space are achieved by choosing the characteristic frame construction of six reinforced concrete frames. Besides, the frames as well as additional steel pseudo-codes are part of the representative eastern main facade where, a binary code, representing the main communication language of the IT sector, is created with the combination of slopes (1) and verticals (0),. The following pattern can be observed by looking at the building from the outside 0100 1001 0101 0100 - IT.
