Two raisecid, airy cubes with prominent lines of slabs, which emphasize the horizontal nature of the volume in the spirit of Novi Beograd architecture, form the space of an inner plateau. Cubes are erected to allow for undisturbed passage of people through the plot, to serve as a portal and to emphasize the entrance to the building from the plateau. The cubes are united by the amorphous volume of the amphitheatre.
