Sechseckbau (today: Student Center Schleswig-Holstein)
A windowless concrete hexagon on a glass base. Its façade is decorated with a swarm of small round elements, which make it appear less closed. It is connected to the low-rise building of the Studentenwerk by a small glazed bridge. The shape of the hexagon also appears in the ground plan of the Audimax building next door. In addition, a concrete hexagonal grid can be seen on the floor next to the hexagonal building.
