The £19m scheme is for pupils from the local area with profound and multiple learning difficulties.
The practice, which has been selected as a Department of Education special school trailblazer, based the design on the 'big roof principle' which aims to minimise circulation and maximise teaching space.
The scheme takes in 'age-appropriate key-stage pavilions' arranged around a central space covered by this 'big roof'.
Two- and three-storey elements at the perimeter of this space will house support accommodation and office space.
The project is scheduled to start on site in September this year, with completion planned for Spring 2008.
