A range of different materials were used in this project: Gutters are made of concrete, the courtyard is covered in robust asphalt, plains and open basins are covered in lawn and the rain garden hosts a great variety of plants. Some of the gutters were painted with red paint in order to highlight their function.
The two central rain gardens in the courtyard are designed as small “rainforests”, with dense bushes of birch trees, dogwood bushes, grasses and stepping stones, whic invite the children to explore the space in both dry and rainy weather. The plant selection is robust and the plants can withstand daily use and changing weather conditions. To minimize maintenance, the rain beds are filled with gravel, which acts as a weed inhibitor.
