Due to the increase in the number of classes at the Heinrich Hertz School, the school needed more space for general education as well as for the GTS area.
The planned L-shaped extension and replacement building was built on the site of the linear building H/J (two-storey pavilion), which was to be demolished, with an extension to the existing pavilion E.
On the upper floor, with the same wing formation, there are three further classrooms with associated differentiation areas and the H/Blin BZBS staff room as well as 7 HHS classrooms. By dividing the building into compartments < 200 m², areas for seating niches and central learning zones can be designated along the escape routes.
Due to the different space requirements for the ground and upper floors and the desire to create a canopy, the upper floor protrudes to the west side of the schoolyard above the entrance area and forms a rain-protected recreation area.
