Located in Givors, in the southernmost part of Greater Lyon, the 11-hectare site with a rich industrial past is still home to oil activities in the immediate vicinity of the Rhône. Positioned at the mouth of the Garon, this sector is a singular place of the Lyon metropolis, which constitutes a particularly strategic space to imagine new links between the city and its river. Simultaneously characterized by strong constraints and genuine landscape qualities, it is notably served by the railway station of Givors-Canal in the north and by a potential river stop in the south. In the context of the energy transition, the research aims to explore through the architectural project the multiple challenges and potentialities of the site reconversion into a mixed-use neighborhood. At the programmatic level, the visions are based on the prospective principle of a certain mix of housing and activities, with increased attention paid to the issue of housing in an urban environment. Relevant reflections on the implementation of a research center in the field of energy, and a diversity of public spaces considering the singular characteristics of the site, are also part of the approach.
