Fulham Prep School occupies beautiful purpose-built Victorian school buildings fronting onto Fulham High Street in London SW6, previously occupied by a Church of England Primary School.The school required additional space for a multipurpose hall to be used mainly for indoor sports activities, as well as changing facilities and a new medical inspection room. The proposed scheme provides a clearly defined entrance to the school building under a glazed walkway, plus defined routes to the playgrounds and sports areas.The curved roofs over both buildings provide more height internally, resulting in a better internal environment, and also a pleasing external form.The school is taking the opportunity of making the buildings fully sustainable and creating education opportunities in sustainable construction for its pupils. The buildings are constructed using a prefabricated solid timber panel system. Wood fibre insulation boards are applied to the outside of the solid timber structure. A sedum green roof forms the roof of both the buildings.
