Work has begun on a multi-purpose building made of cardboard for Westborough Primary School, Westcliff-on-Sea, Essex. Funded by the Department of the Environment, Transport and the Regions through the Partners in Innovation Scheme, the aim is to use 90 per cent recycled materials and to make the resulting building 90 per cent recyclable. Although planning permission is still being sought, the prototype should be ready for use by March 2001. The research team, led by engineer Buro Happold, will be working directly with the cardboard manufacturers to exploit the material's strengths. The school is also keen for the pupils to learn from the experience.
