The site is vast (300 km2) and the goal is to create a regional-scale territorial strategy. A task that is all the more demanding given that this territory, made up of a mosaic of urban, agricultural, natural and industrial areas, shares its borders between Germany, Belgium and the Netherlands.

To promote the emergence of a tri-national identity, the team led by Agence Ter chose to interconnect the fragmented spaces rather than homogenise them, and studied the deconstructed strata of the territory, leading to the discovery of an underground coal seam that extends across the three countries forming a significant field shared by their populations. The designers suggest, on the surface, an echo of this invisible layer: its footprint becomes that of the «Green Metropolis» project, extending beyond the administrative limits.

The new territory is structured by two main roads: the green road and the metropolitan road. The former connects the regional parks following the line of the river banks; it is a long bike lane giving meaning to these natural spaces, a physical location. The metropolitan road links the main urban centres.

In designing the Green Metropolis project, Agence Ter and its associates participated in the development of a strategy offering a common destiny for the fragmented spaces of a cross-border agglomeration.
