The education system is a large-scale manufacturing process. Kinderfabrik proposes a ‘new Metabolism’ influenced by the industrial history of the site as Ammonia Works. The school is designed for children aged four to six and the design consists of interconnected capsules and an abstractionist playground. The importance of a capsule and its required illuminance dictates its height above ground. As the day evolves, the children’s movement gradually fills the school, resembling pipes in a factory. The capsules’ lightweight steel frame is supported by an external box frame. As more children attend Kinderfabrik, classroom modules are added by expanding the box frame and lifting new capsules onto the structure. Duckweed is extracted from the River Lea and synthesised through pipework entwined between the structure and architecture to provide shading in the form of large-scale chromatography artworks. Children contribute to the synthesis of duckweed by playing in the playground. The development of the climate crisis will drive the artwork to be greener for a greater proportion of the year. Monthly recordings of the artworks educate the children on the climate crisis.
