In 2021, 353 development projects located in the 68 station neighbourhoods accompany the arrival of the Grand Paris Express. They represent over 32 million m² planned, 20 million of which remain to be built. These projects represent a ground surface area of 12,000 hectares, 700 hectares lie within a perimeter of 800 metres.
This note deals with the main findings and key figures detailed in the two studies online on the Apur website, one published in November 2019 devoted to the 35 neighbourhoods whose stations will be running by 2025 and the other, published in February 2021, devoted to the 33 neighbourhoods whose stations will be running by 2030. These studies were carried out as a continuation of the work of the Station Neighbourhoods Observatory, set up in 2013 and piloted in collaboration with the Société du Grand Paris et la DRIEAT Île-de-France.
The analysis of projects shows that the 68 Grand Paris Express station neighbourhoods are at the heart of a major construction dynamic which anticipates the accessibility advantages linked to the arrival of the metro in the majority of the neighbourhoods. In addition, the neighbourhoods of the stations in the east of the metropolis are developing more slowly than those in a wide sweeping western half that reaches from Plaine Saint-Denis to the Saclay Plateau via La Defence which, as always, is a favourite with real estate key players. Beyond the diversity of situations observed among the 68 station neighbourhoods and the 353 projects analysed, the point in common lies in the limits of these projects, led by different key players: insufficient public space and nature and the need to strengthen the links to be woven with what is already there, or even with the other projects developing in the vicinity.
