This unusual playground building entices children to explore it. The design combines references to an old witches’ house with contemporary sculptured architecture. There are three modules on the ground floor that have different functions: selling confectionery, sanitary facilities and storage. An enormous sloping roof provides atmosphere and protection from the elements. There is a roof garden on the first floor that gives a view over the entire playground. The detailing is unusually fine for a playground building. The materials used consist of a steel load-bearing construction that is clad with grey wooden planks.
