This case study is based on the example of a real middle size town of which a large pericentral sector (orange on the map) must be the object of progressive urban renewal because, being next to industrial brownfields, there are numerous enterprises still in place and functioning even though their premises are obsolete and run-down. The objective of the local authority is to prioritise the renewal of this sector in order to meet the need for housing and business premises without eating into agricultural space.

A new industrial estate (pink on the map) must be developed to the west, inside the ring road. It can serve to relocate existing activities. The goal of the local authority is in fact to restructure the vast pericentral sector while maintaining and improving the housing/employment balance.
