Planning the design of the Bourget train station raises the question of how such infrastructure fits into the landscape, ecological, and urban framework of its territory. The site, insular while traversed by major flux, presents a gigantic enclave that brings into question its quality and status as public space on many levels.

At the larger level, the masterplan is based on a system of plantings with variable densities. Such a plant structure ties the site closely with the surrounding landscape and biological continuities. The task here lies not in creating a system that conceals, but in one that provides essential physical support. Areas of trees are created that are immediately visible and adaptable, foreshadowing future urban extensions with clear geographical anchorage.

At the smaller level, despite the interesting and balanced multifaceted configuration of the site, intermediate spaces and plants are today still absent. The train station square emerges as a major public space. Its mineral surface is planted with large trees that follow a fixed layout. The square provides a clear and open space for a number of different uses: the free flow of pedestrians, a smooth and perceptible flow of vehicles.
