This essay critically read the peri-urban space with respect to its design potential, starting with a conversation with François Jullien, stressing some concepts expressed in his book "Vivre de paysage ou l’impensé de la raison" (2014). The aim of the essay is to establish a parallel between the landscape concept expressed by Jullien, referring to the Chinese tradition, and in particular its conditions of space in-between and écart, with the peri-urban territorial condition. This ap¬proach seems particularly useful to overcome the descriptive and prefigurative limits linked to the topological condition of this space: fragmentary, hybrid, discontinuous, contradictory. The holistic vision supported by the French philosopher seems to emphasize the potential of the peri-urban as a - space in transition -, and helps to get out from some persistent conceptual dis¬ciplinary hitches . Thus, the contamination between this interpretation of the landscape and the studies coming from the tradition of landscape ecology can contribute to a new discourse on the peri-urban landscape and the possibilities of its re-signification through a renewed idea of project.
