The Grand Paris Seine Ouest (GPSO) territory, 320,000 inhabitants, is already the densest within the urbanized areas of the Greater Paris Metropolis. It has just adopted its first draft local intercommunal urban planning plan (PLUi), which will translate these objectives into concrete terms.
According to the regional housing and accommodation plan (SRHH), the GPSO territory should build 2,000 housing units per year. At the same time, the Territorial Coherence Scheme (Scot) recommends strengthening open land to tend towards a minimum of 30%.
