6919 Marconi, starting point of the CHANTIER project, is located in a hybrid urban zone (residential, industrial and commercial) along a train line. For many years now, Prost individually and collectively initiated on this 1 800 ft2 lot different types of occupations, such as workshops, projections, launches and urban camping. Today, many city dwellers are challenged and drawn to this vacant lot as a space-time of stopping, slowing down and spontaneity in an era of acceleration and increased control.

Unlike entertained-animated spaces that are overly programmed and codified, as we know nowadays, the vacant lot stays wide open for imagination (without dictating how we behave, move and travel). According to the theoretician Benjamin Delmotte, this allows “multiple never-ending beginnings.”

For the CHANTIER project, Jean-François Prost will initiate an intervention offering a support on which other individuals can act and contribute to define its character and specificity in transformation. This participation and (co)definition process suggests an eventual negotiation about the land, which is vital for democracy. As the urbanist Jane Jacobs said : “Cities have the capability of providing something for everybody, only because, and only when, they are created by everybody.”

The proposed actions will explore the theme of the vanished, existing and prospective urban diversity, as well as the vagueness of the place, and the unfinished aspect of the construction site as a vector for co-defining the city.

It is in this spirit that the CHANTIER project is being developed. More news will follow soon about the planned actions.
