Therefore, we put the main idea of the design on elements that are relaxing and reducing the seriousness of space. In the first step, we considered the main spaces that included the management room, the main meeting room, the administrative section, the entrance section and the service spaces. We considered the administrative section as an open office, and the spaces of the meeting room and the entrance section were filters between the administrative and management departments. Service sectors were all in the same direction, in one third of the eastern part.
