Hochrad Grammar School

Gymnasium Hochrad is a secondary school for grades 5-13 in an attractive residential area on the banks of the Elbe just on the outskirts of Hamburg.
The school will be expanded with a new building for classrooms and canteen. Old sports halls are to be replaced by a new one.
Due to limited space, the idea is to place the large volume of the sports hall at -1 level on the sloping terrain. This creates a more harmonious whole in terms of height and makes it possible to utilise parts of the hall's roof to expand the schoolyard. The stairs between the existing and the new outdoor area create a nice seating oasis with a view of the schoolyard to the south.
The classroom building itself is built as a two-storey, lightweight wooden structure on top of the other part of the sports hall, which minimises the carbon footprint and saves space.
