The gymnasium at the Franz-Mehring-Schule replaced the previous building that was structurally very obsolete. The narrow financial means from the Konjunkturpaket II economic stimulus package were used to create a compact building that generates a new identification point on the heterogeneous school grounds through precise design elements. The single-field hall reflects the compacted parameters of the construction task: the largest possible space allocation plan, minimal open space consumption and high energy requirements.
