During the excursionof the Pentecost week, the bamboo workshop from the previous winter term 2021/22 was continued in Hoogcruts. The students of RWTH succeeded in almost completing the roof construction for the rammed earth walls despite rainy weather conditions. To span the surface, the bamboo was cut in half and bent with heat into the appropriate shape. After cooling, the bamboo retained the specified shape and could be mounted on the roof structure. The matching roof skin has already been sewn to a large extent from textile. However, this will be attached at a later date.
