Redland Green School by BDP almost merges into the hill at Redland.  Described as the ‘school under the hill’, the main three level teaching spine is situated under the existing hillside beneath a sloping green roof making for striking commercial photography and architectural photography.  The natural contours of the hill are carried over the spine to create an inspiring open air learning environment, which overlooks the city of Bristol and surrounding countryside. The main route through the building is a 12m high 'Street', a thoroughfare designed as a means of access to different zones of the site and a congregation point for students as shown in the commercial photography and architectural photography.  The roof of the street is finished in a clear twin wall flexible plastic that provides insulation and bathes the route with natural light.  The material is similar to that used in the geodesic domes at the Eden Project - see architectural photography and technical detail here http://www.adamcoupe.com/portfolio/entry/313/eden_project/about.htm.
