The summit school is an SEN school for 11-18-year-old ambulant pupils with learning disabilities. The scheme was divided over 5 buildings to allow each pupil's environment to be tailored to their own personal requirements. To harmonise 5 buildings and bring about unity between the internal and external spaces, a 4m x 4m grid system was employed to divide the site and locate each design element. A range of indoor and outdoor sensory spaces, lighting control via orientation and window size and position, and the implementation of colour as a navigation aid, all provide the pupils with a space that is designed to allow them to have a positive, considered experience of school life parallel to their mainstream peers.
