Shared Space is a simple phrase. It was coined at the outset of the Interreg-project, providing both a title and a broader vocabulary with which to address a complex set of issues arising across the European Union. Largely as a result of the project, the phrase is now widely used and recognized around the world. In common with all language, the meaning of the term ‘Shared Space’ is evolving as experience is gained and knowledge expands. New ideas, new implications, new possibilities, new problems, new issues and new values continue to challenge and strengthen the original concept. Testing the principles against different physical, social and cultural concepts in neighbouring North Sea countries has greatly strengthened the relevance and understanding of new ways of thinking and adapting our built and natural environment.
