The extension to the comprehensive school at the Botanical Gardens contains classrooms for years 10 to 13, a large multifunctional room for use as an assembly hall, events and canteen, administration rooms, a self-study center, PC rooms and music and art classrooms. The building consists of a three-storey block measuring approx. 37.5 x 20 m and a trapezoidal, four-storey structure arranged orthogonally to the block. The shape of the building defines appropriately proportioned schoolyard areas in conjunction with the existing school buildings.
