reception time for migrants is divided into two phases. A first one, on the site. Here we create a point of convergence, a generator of urban energy to bring the city to the new arrivals. This center takes the form of a set of porous pavilions drowned in a plant canopy forming a boundary. The newcomers' center.
A second, in the urban fabric. Once the time of adaptation is over, the newcomers are propelled into the city. Associated with small neighborhood programs, housing colonizes the urban landscape. In the form of small towers with a wooden-concrete structure, they come to occupy the hollow teeth and other ur- baine holes.
The two systems form a programmatic interdependence. They constitute a new network of flows in the territory. It is an archipelago that expands at the rhythm of arrivals.
