We designed a conference hall with a 1500 m² usable area for the closed hangar parts in the Kayseri Free Zone. The sound ambience is very high quality and the stage is given a good slope so that all the audience can see the viewing angles clearly. Thanks to the design made to the sound echo, the reverberation and circulation of the sound are optimized. It is an exemplary hall where the free zone’s seminar and conference are held.
