Abstract clinker brick tulips set an architectural accent
On each side of the entry area 3.50m wide, prominent façade strips in clinker brick "grow" some 40 m. upwards and end in a clinker brick tulip which extends around 2 m. above the roof. A building projection in the opposite corner area acts as an optical counterweight. Covering 4 stories it is also made of clinker brick.

The solution to the problem lay in dividing the "tulip" in plan into individual segments, starting from the base of the rounding, so that the segments could then be constructed at a scale of 1:1. The best solution from both the cost and technical points of view was to split the upward curvature into 13 separate prefabricated parts with three different radii which ran to zero at the base. This approach meant that the predefined curvatures could be incorporated precisely.
