We all begin and end our days by walking the same streets that lead to our homes. What happens when we cease to consider the space of the street as a circulation route and instead see it as another place to live?The network of streets that forms a neighbourhood comes alive through the uses, rituals and habits of its residents. What, then, are the ingredients that guarantee conviviality and an attachment to our neighbourhood? Through tireless observation of the rue de Belleville and encounters with its inhabitants, we will discover how conviviality is expressed on a daily basis in a complex urban environment.Here, the questions of the interior architect lead us outside, through our familiar public spaces.
