Northwest of Shanghai, on the site of the city's market and in contact with the Shanghai West station, the project consists of building a 600-hectare centrality zone. This very ancient site still contains historic areas. Aside from the Zhenru pagoda, this heritage is minor (market hall, old suburban towns, buildings from the 1930s, subsidised housing) but it bears witness to the entire history of the district. The project seeks a balance between these places integrated into a linear park, a “lower city” that respects the scales and operation of traditional Chinese streets and an upper city (the emergences) representing modernity and enabling a response to the density goals for the district. Offering extremely differentiated living spaces is a way to ensure historical and physical continuity.
