Two primary schools, a day-care centre and an area health authority share a new, green complex: a Community School in the neighbourhood Osdorp. The goal is to encourage interaction between the groups. The design allows each individual part of the building to function at its best. Each classroom, for example, has a ‘block’ containing a cloakroom, toilets, kitchen, (computer) work stations and a mezzanine. The whole complex surrounds two inner ‘courtyards’ in the form of a communal assembly hall and winter garden. This forms the basis for the placing of two playgrounds. One, for the youngest children, is safely fenced off, the other, for the older and local children has a large platform. The whole supporting section of the building is made of wood, making it light in terms of weight and in its overall effect. Wood is also a tactile, soft, colourful and varied material, this makes the whole building much more welcoming. The project was nicknamed 'The Frog' (in Dutch: De Kikker).
