Children across the country will be able to learn about a £350,000 extension to St Pancras School in Lewes, East Sussex, thanks to a pioneering new scheme. Masterminded by BBM Sustainable Design, every stage of the nine-month project will be filmed to create an interactive CD-ROM. The CD will then be sent out to junior schools as part of the Classroom of the Future initiative, which is being run by the Department for Education and Skills. The two-storey arts and science block will be insulated with recycled cellulose and clad in locally-grown sweet chestnut wood taken from worked coppice land. The new extension is due to open in September 2005.
