Designing a new mode of organisation, an urban image that can be shared in the ZAC de l'Horloge and in the Bas Pays of Romainville more generally: Using simple principles, the project proposes an equation that brings together soft mobility, nature and re-use of the heritage.

Three values guide the action and organisation of the urban project, contributing to a shared comprehension of the project and guaranteeing its urban integration:

- Mobility and connectivity: to promote a city of proximity

- The landscape and natural continuities: re-establish the natural continuities; the link with nature is the second determining value. The topography of the town and the creation of the leisure park are the foundational elements of this approach. In the relation between upper Romainville and the canal we imagine a “resurgent” nature following the theme of hydrology and giving character to the new town.

- Complementarity of usages and typologies: consume less space, use the space better; the theme of re-use is the third principle that structures the project. It is a “post-functionalist” concept that applies to territories, materials and equipment. It, of course, includes a patrimonial approach to the site, but will go beyond the historical value to include the environmental issues the project raises.
