The urban project of arranging the business zone of the IT center puts a lot of emphasis on public use of space and a series of pedestrian paths, public areas and interactive parks strongly connected the scope with man, thus raising the issue of using public and social space in this architectural and urban complex. Due to the spatial disposition within the scope, the plot is positioned with the western facade along the public square and the eastern facade towards the semi-public space. Creating a link between these two public spaces. The building that will be partly the facade of Gacka Street has a big role in creating the image of the space. The tower and the lamellae are interrelated. The lamella on the ground floor, indented in volume, creates covered public areas and time draws public space into the building. The tower and lamellae have a public ground floor and top floor. On the lamella, this is achieved by activating the roof, and on the tower by the attractiveness of the view provided by the top floor. The lamella and the tower differ in additional contents, the tower is recreational, while the lamella is cultural. To contribute to the activation of buildings and after working hours for all external users who have the opportunity to use the buildings. The spaces inside the lamella are connected horizontally, and in the tower by galleries vertically, which can be read on the front of the buildings. The materials are glass and concrete that contrast with each other.
