The temporary information box was built from June until October 1995 and located amid the major construction site Potsdamer Platz. It was planned as a centre to inform the public of the new developments in the heart of Berlin.
The 23 m high building was clad with red enamelled steel sheets and had glazed corners, allowing a view to the constantly changing construction site. The floor slab cantilevers 7m above the ground on concrete-filled steel tube columns with a diameter of 40 cm. The building structure remained nearly completely exposed, expressing the architectural concept.
Being designed for temporary use, the structure was carried out as a bolted steel structure. The exterior columns consisted of concrete-filled steel tube columns, the interior columns of concrete-filled composite columns.
