The workshop focussed on ideas about building - environmentally harmful materials and environmentally friendly alternatives were playfully explored and compared in the form of a sticker collage. The children were then able to paint their dream mushroom house. The main aim was to introduce the children to mycelium-based composites as building materials and to stimulate their imagination. This resulted in wonderful ideas and jointly created buildings. In collaboration with Johanna Ficht and Núñez Guitar.
