Using cardboard components wherever possible, this new classroom is built up of 90% recycled materials and is designed to be recyclable itself at the end of its life. Collaborating extensively with the clients, the construction of this prototype building incorporated an educational process for the children, who learnt about recyclability and were asked to collect cardboard for its construction. The building is multifunctional, incorporating a changing room, toilets and a classroom that can adapt to an after school club when needed. The prototype cardboard building was jointly funded by the project’s research partners and the Department for the Environment, Transport and the Regions (DETR) through the ‘Partners in Innovation’ programme
