The Learning Environments Campaign sets out the critical challenge for everyone involved in school design and construction: how can we create schools which are truly fit for learning in the 21st century? This prospectus proposes a real alternative to the standardised ‘outside-in’ approach that dominated the 20th century and produced the schools we are now looking to replace. As government commits its largest post-war spend on new schools, the proposed ‘inside-out’ approach provides a new and validated perspective.
