The urban study of this railway wasteland in the heart of Alfortville seeks to address the following questions:

How to live close to the tracks? What lifestyle should be proposed in a Paris Region context where we do not wish to reproduce the constraints of the dense hyper-centre? So how can we benefit from another relationship with the outside world and its immediate environment? How can we also build without reproducing the constraints of the social groups of the last century? How can we also offer an alternative to the single-family home in an ecological context where we must save the territory and consider concrete collective sustainable solutions in terms of energy, water, sharing of services, health, nutrition, and therefore the quality of the living environment?

Here, the creation of the city by a living, active landscape, appropriable by everyone through an iterative process of co-design and guaranteeing respect for lifestyles, provides answers.
