This three year project aims to enable children in Islington to design and build dens and tree houses in 24 existing play areas, including adventure playgrounds and city farms. The project will benefit 5,000 children aged 5 to 16 years old, including children with disabilities as the project, including some of the completed structures, will be fully accessible to children with disabilities. A proportion of the tree houses will be built either at ground level or will be slightly raised structures.
