The downtown district consists of two main areas. The former area of Ahlers GmbH Goldress where the Design Museum by Frank O. Gehry (M.art.a) and the Competence Center of the German furniture industry and was the former site of Deutsche Post, in which a technology center was built (in the listed stock). On the open spaces of the post area is a parking garage and another office building developed and planned a hotel. The crossing area at the entrance of the office building has been transformed into a roundabout, where a sculpture of "The Ball" a 3.5 m wide steel ball of the Milanese artist Luciano Fabro stands. On the median strip, a few hundred meters long excerpt from the poem "The Ball" by the poet Rainer Maria Rilke was installed by stainless steel letters.
The task was to build an office building that meets the demands of today's modern, flexible and cost jobs.
The draft provides for a six-storey building with a facade stringent hole that presents itself from the plan as double loaded stairwell. Due to the strong topography on the long side of the building the face of the basement in his full height stands out of the soil and thereby allows a ground level drive into the garage. The basement houses next to 26 parking spaces, cellars and technical rooms and the foyer, that by a two-story open, column-free hall opens towards the roundabout. In the upper floors are office units. Due to the dual side orientated office concept the vertical access, meeting rooms, kitchens, toilet units and equipment rooms are situated in the central zone and the jobs are oriented along the facades. On the top floor is located a spacious living unit, which makes it readable by the framed, roofed terrace and a further office unit, which is graded against the outer walls back.
