L'architecture commerciale à l'usage des villes : ambiances, pratiques et projets

Abstract : Business architecture has largely developed itself for decades in the form of private insular spaces. These spaces show a multi-focusing of the offer, and generate areas difficult to treat and integrate. This research is precisely about the qualification of business facilities and their relationship to their close urban context. We take them as generators of specific sensitive space and through the angle of their take on the city. The objective of this thesis is to analyze the effects of implanting large-scale businesses in nearby areas, and to formulate conception criterias about their relationships to urban fabric and nearby landscapes. What are the factors that allow a better articulation of the business facilities while keeping attention to their context, so as to rethink the urban strategies and the conception designs? What are the evolutions in the structure of their construction, and the evolutions in the nearby public spaces? How could we get public and private actors to integrate dimensions of quality, including ambiances in the planning of retail trade in the city? The hypothesis of this work is to give attention to the spatial and perceptible limits between private business areas and public urban areas, using as a starting point the fact that it is one of the necessary conditions to develop urban opportunities in the general area of business facilities. To validate this hypothesis, we have chosen to study two cases: the Beaulieu shopping centre that was rehabilitated not long ago on Ile de Nantes, and the shopping and leisure centre Carré de Soie in Vaulx-en-Velin. The goal is to explore the spatial qualities of the two business facilities and their surroundings, all this while questioning the urban strategies deployed in these two operations (the first on is a rehabilitation and the second one is a new creation). The analyze of the pre-exiting situations and of the integration process allows to realize the origins and the mechanisms of the project. The in situ approach is done from nearby spaces around business facilities to get spaces accessible to pedestrians as well as the question of atmosphere and use. This reasoning lies on discussions with the main actors of the business planning and through the observation and in situ measures. For these investigations, it is possible to distinguish different grips on city business. The identification of these ambiance layouts allows us to explore three possible scenarios for the future, and to specify the levels of urban continuity for business on the territory. They directly affect the planning and conception of business in the city, so as to manage multiple existing business facilities, to anticipate the evolutions of the business sizes, and to suggest new nearby space around facilities with their nearby context.
