The "Petite Ceinture" is an iconic heritage of Paris. It is represented by its bridges, tracks, station buildings, and auxiliary constructions: depots, ticket offices, and other service buildings. Some of these have already been restored, like the Gare de Montrouge-Ceinture and Gare de Passy-la-Muette, others are being prepared for restoration, and some are abandoned or have been demolished. For example, the main building of Grenelle Station at Place Balard has not survived—only archival photographs remain—but the ticket office/entrance building still stands.

According to maps, it housed some businesses some time ago, but for several years now, it has appeared abandoned and fenced off. It is sad to see it in this state, as it is a remarkable example of the ordinary architecture of its time, reflecting the tastes and style of its era. To reintegrate this building into the ensemble of Place Balard and make it a local attraction, this project was developed.

The concept envisions opening a small café in the space of the former ticket office of Grenelle Station. This type of establishment, when managed well, can always be profitable, bring life to the area, and help preserve the small-scale architectural heritage that remains in this part of Paris' "Petite Ceinture."
