The European Spatial Development Perspective (ESDP) is the product of a north-west European planning tradition. This article discusses the role of north-west European concerns in particular the use of the concept of poycentricity, in the making of the ESDP, and the application of the ESDP in the North-west European Metropolitan Area (NWMA), more in particular in Germany, the UK, The Netherlands and Belgium. The article also explores the future of spatial planning as regards north-west Europe. Much will depend on how Community policy will adapt to the enlargement of the European Union. However, it seems certain that existing member states, in particular those in north-west Europe will see their share in the structural funds evaporate. This may give added significance to INTERREG IIIB respectively to the successor of this Community Initiative. In addition, concepts like territorial cohesion and territorial management may become functional equivalents to that of spatial planning, for which the Community is said to have no competence.
