Hamonic+Masson's mixed-use development is situated in a brownfield site on the Arsenal eco-district in Rueil-Malmaison, located in Paris' first ring of suburbs and approximately 8km to the west of the city. The idea is to bring new life to this sector and improve the surrounding population's quality of life. A new metro station will be built as part of the Grand Paris Express development, creating a new dimension for the town and the need for surrounding urban developments, housing and services.
