The city of Ulis, conceived in the Seventies and resulting from the doctrines of the “Charter of Athens”, is founded on the town planning of flagstone, the zoning and the separation of flows of circulation.
Its centre town really was never finished: it is characterized by the vacancy of the land reserves at the entrance of its territory, and by the two arteries in road matter which cross it and represent true obstacles with the reunification of the districts. Several objectives appear:

  1. To find the original ground and the common right of the city by leaving the town planning of flagstone, the turns and the bars as well as the separation of the uses.
  2. To change the image and the attractivity of the city to promote a social diversity thanks to the arrival of the University Pole of Excellence, in the vicinity, on the Plate of Saclay.
  3. To improve quality of the living environment of the inhabitants in a major and durable way by preparing the city with its change necessary and its relation fertilizes with nature.

Thanks to this study, which extended on more than 10 years and required the intervention of several project superintendents that we coordinated, our team undertook a research deepened on the question of the urban renewal within Sustainable development. That led us to join again with the vocation first of Ulis, that of “City in the countryside”, thanks to a Governance strongly supported by the elected officials and the population.
