For the Villejuif - Gustave Roussy station district, the opening of the line 14 and 15 stations in 2025 will considerably improve accessibility to a district with 7,170 salaried jobs, most of which are linked to the Institut Gustave Roussy, previously served only by bus. The arrival of the Grand Paris Express network will also boost project development. 142,400 m² of housing, 172,767 m² of offices, 20,000 m² of facilities, 6,000 m² of hotels and 20,000 m² of retail space are planned for the ZAC Campus Grand Parc. Six new streets and a planted mall will improve pedestrian links between the Institut Gustave Roussy, Campus Horizon and the train station.This socially mixed neighborhood, characterized by a strong presence of vegetation and green spaces open to the public, is already undergoing a major transformation. Housing supply is set to almost double once the ZAC Campus Grand Parc is completed.
Launched in 2013, the Observatoire des quartiers de gare du Grand Paris Express is a partnership tool that brings together the Atelier parisien d'urbanisme (Apur), the Société des grands projets (SGP), the Direction régionale et interdépartementale de l'environnement, de l'aménagement et des transports (DRIEAT) and the Institut national de la statistique et des études économiques (Insee) as well as the Établissement public foncier d'Île-de-France (EPFIF) and the Institut Paris Region (IPR). The aim of the observatory is to report on the urban and social transformations linked to the arrival of the metro, at the level of station districts, lines and the network.
Ten years after the first survey, a new phase of the observatory has begun. In keeping with the timetable for the start of operations, the new studies are based on the same perimeter around each station, with an 800-meter radius corresponding to the immediate area of influence covered in a 10-15 minute walk. They also include the main indicators for comparative analysis.
Seven themes provide a fine-grained overview of current and future urban changes - Living environment - Population and jobs - Housing supply and prices - Local life, uses and new centrality - Accessibility and mobility - Environment. They are accompanied by a simple datavisualization, accessible to all from the Apur website and updated every year.
