La Petite Ceinture is a former double-track railway line that used to run around Paris within the boulevards des Maréchaux. Its rails are today invaded by a wild flore with an unusual biodiversity, counting more than two hundred plant species and more than seventy animal species. Since 2007, many section of the railway have been regularly opened to the public for regeneration projects such as the sections in the 16th arrondissement, the 14th, the 18th, and so on. However, a large part of the railway still remains abandoned and unattractive for the public. Mon Petit 20ᵉ, as the name suggests, is an urban design project that deals with a section of the railway located in the 20th arrondissement, known more specifically as the O3 Section, which compared to other parts, is not active and sadly influences other surrounding buildings into abandonment. The project aims to open the rails and the public buildings attached to it, to the surrounding environment by introducing three strategic layers of interventions:

1. Social: reuse and build new public attractions;
2. Ecological: extend the park & add urban farming
3. Soft Mobility: add new sustainable accessibility

In terms of design, a series of different interventions are proposed, such as Cultural Hub next to the RATP de Charonne-Ligne Building which will provide many new public spaces for social integration and cultural activity; Park Extention of the existing park (Jardin de la Gare de Charonne) along the rails and connected to the urban farming to further increase biodiversity and stimulate the locals to engage with landscape; Urban Furniture along the park; as well as Soft Mobility lanes with bike parking and electric charging spots for e-bikes and scooters, always following design for all principles and promoting sustainability.
