Marseille

In July 2017, Ginkgo acquired the former Legré-Mante factory in the Madrague de Montredon district of Marseille's 8th arrondissement. Located on the seafront, the site covers an area of 17 ha, 9 ha of which are adjacent to the national park of Calanques.

Widespread soil contamination of heavy metal has been observed, including arsenic and lead. The remediation strategy combines physical containment, hot spots offsite treatment, and in situ biological phytostabilisation using local plant species.

The project, drawn up in partnership with Constructa and the architectural firm Kern+Associés, proposes a predominantly residential development.

Overall, 85% of the existing buildings are to be refurbished, while 9 ha of protected area are to be transferred to the national park of Calanques. The future project will allow the area to be opened to the neighbors and public, offering a green corridor between the natural park and the sea.
