In this international school, up to 450 pupils from all over the world undergo full-time ­education from primary school to university entrance level. The language of teaching is English. The new pentagonal structure has been fitted into the Bergstrasse school village, which dates from the 1950s.

The main entrance in the plinth storey and three further points of access on the upper floor link the interior of the building with the network of routes across the campus. The classrooms are laid out along galleries around a large atrium with a roof light. The central feature of the spatial layout is the trapezoidal-shaped exposed-concrete staircase, the steps of which can be used as informal places to sit during breaks or as a tier of seats for school events and performances.

The playfully distributed coverings in dark stained oak provide areas for three to five pupils. Next to the concrete balustrade walls are the main flights of stairs. All steps were constructed with precast concrete elements with rounded arrises. In addition, bush-hammered non-slip strips were worked into the surfaces of the treads.

The exposed-concrete interior of the school, with its rough, workshop-like character, is meant to encourage the children to bring their own vitality into the building and lend it colour.
