The urban concept developed by the municipality extends the network of routes and views through the site. The municipality's desire to establish 'openness' through an equal relationship between landscape and building was central to the success of the plan. However this ambition had to be negotiated with the market requirements for programmatic density. This led the municipality to create the concept of 'schotsen'. A 'schots' is considered a compact building block eroded internally by new forms of semi-public space. Thirteen 'schotsen' are distributed across the site in an open landscape that operates as a filter zone between the city centre and 19th century housing extensions. S333 have developed Schots 1 and 2, which forms a strategic link in the city's ecological corridor linking the canal with an existing urban park, as the first phase of the project on the original Europan 3 site.
