L’image des ruines est quasi absente dans l’art traditionnel en Chine. Mais l’usine abandonnée et le bâtiment démoli sont régulièrement présents dans le cinéma chinois contemporain depuis la des années 90. À plusieurs reprises, Jia Zhang-ke s’est inspiré du champ de ruines tandis que Wang Bing a exprimé la nostalgie pour le vieux quartier à Shenyang dans une interview à propos d’À l’Ouest des rails. De leur côté, Wang Quan’an, Wang Chao, Lou Ye, Zhang Yang racontent souvent les histoires dans le contexte de la grande vague d’urbanisation du pays. L’image des ruines, comme symptôme, est surdéterminée dans leurs films.Ce travail tente d’analyser l’esthétique des ruines par la pensée de l’anachronisme. Dans l’image filmique, le champ de ruines et le chantier ne sont ni les simples fétiches intemporels, ni les simples chroniques figuratives. Ils sont des montages de temporalités différentes par lesquels on peut entrevoir l’écheveau de notions hétérogènes, des symptômes qui font apparaître le pouvoir impérial de la Chine ancienne, des désirs de la fuite hors du monde quotidien. / The image of the ruins is almost absent in the traditional Chinese art. But the demolished building and the abandoned factory have become the most important urban landscape in the contemporary Chinese cinema since the late 1990s. The field of ruins inspired Jia Zhang-ke to write screenplays for films and Wang Bing expressed nostalgia about the old district of Shenyang during an interview. On their side, lots of filmmakers are interested in social realty in the context of urbanization. So the image of the ruins is overdetermined as a symptom in their films. This thesis is trying to analyse the esthetic value of the ruins by using the idea of anachronism. In the image of film, the field of ruins and the construction site are neither the timeless simple fetishes nor the figurative chronicles. They are some montages of different time zones, through which a mixture of ideas can be seen. They are some symptoms which can show the imperial power of the old China. They are finally some desires for escape from the concrete life-world.

Since the beginning of the 21st century, the future of religious heritage has provoked consideration within the fields of law, history, architecture and heritage. The origin of this problem is explained both by the decline in traditional worship practices, essentially Catholic in France, from the 1960s onwards, and by the Church’s lack of human and financial resources, which has resulted in the appearance of veritable "religious desert". This process, related to society’s secularisation, is expected to increase because of the likelihood of these two factors intensifying. If convents, monasteries, seminaries and other Catholic religious buildings have already been affected by this phenomenon, parish church buildings are now in turn losing their original function. Quebec has also experienced this phenomenon, but its historical and legal contexts have accelerated the transformation of churches which in turn resulted in the establishment of a "churches Plan" aiming at preserving church buildings by converting them.In this thesis, that pioneering programme is used in relation to the Lyons Saint-Etienne urban area, as a lens through which to read the French situation and as a tool for generating methods adapted to its specific context.The first part summarises the specific heritage and legal knowledge bases from Quebec and France concerning their parish churches, which is necessary for understanding the two contexts. The second part is an observational study, which defines the territory and creates an inventory of the corpus of research. We first provide an inventory of 429 parish churches within the territory studied here. From an analysis of their transformations, we propose three major typologies ("historical", "19th-century" and "20 h-century " churches), Using the cases of church conversions in ou corpus, we analyse the degree of compatibility between their previous worship use and their new uses, and then formulate hypotheses relating architectural interventions for adaptative reuse to restoration theories. The third part is an action-research interventional study. Three representative case studies from each church typology have been selected, in the town of Montarcher, Givors and Villeurbanne. For each case, a participatory approach has been set up with the municipality, inhabitants and associations, in order to propose reconversion scenarios adapted to local needs.This work shows that the demolition of parish churches, widely perceived as a common good, threatens the transmission of local identities. It therefore seems essential to start a global reflection on the evolution of this heritage, one which takes into account territorial issues, citizens' demands and the architectural diversity of these buildings. We show that the architect, through both his sensitivity to the place and his technical, can play a central role in implementing of these reflection. / Since the beginning of the 21st century, the future of religious heritage has provoked consideration within the fields of law, history, architecture and heritage.

La démographie et les modes de vie ont considérablement évolué au cours des dernières décades. De tels changements sont destinés à influencer la conception de l’habitation et ils incluent notamment une série de besoins émergents: s’en suivent des besoins additionnels en espace pour répondre à l’arrivée de ces activités additionnelles au niveau du logement. La planification en vue de répondre à ces besoins émergeants constitue le principal thème de la présente thèse. Dans le cas de la maison unifamiliale détachée, le sous-sol est disponible pour offrir des espaces appropriés à ces besoins émergents. Par contre, une telle ressource n’est normalement pas présente dans le cas d’un édifice multifamilial. La thèse propose un espace additionnel spécifique en vue de répondre à ces besoins émergents : l’espace supplétif. Même si un tel espace n’est pas envisagé dans les publications du domaine, des précédents existent quant à sa présence en planification multifamiliale. Le but de la présente étude est d’offrir des lignes directrices quant à la conception et l’intégration d’un tel espace supplétif. Elle va s’appuyer sur l’approche systémique en raison de la logique de déduire la solution à partir d’une analyse de l’objectif. L’application de l’approche systémique implique donc que tous les critères correspondant à la nature spécifique de l’espace supplétif seront extrapolés à partir de l’objectif. Dans le cas la présente étude, ce sont les critères du bureau à domicile qui seront d’abord précisés car il s’agit de l’activité émergente la plus exigeante. Les critères seront traités comme vecteurs d’un modèle générique indicatif de la manière d’organiser l’espace supplétif. Ce modèle visera le bureau à domicile en vue d’offrir les solutions pertinentes et il se concentrera principalement sur les critères d’intimité visuelle et spatiale. La contribution du modèle sera de suggérer des lignes directrices en vue d’incorporer l’espace supplétif à l’intérieur des édifices résidentiels de type multifamilial, ce que la planification conventionnelle n’offre pas. C’est le concept d’adaptabilité qui est à la base de toute stratégie visant à permettre le changement en architecture et en habitation, d’autant plus lorsqu’il s’agit d’un espace supplétif. À cet effet, l’espace supplétif va recourir à l’approche Open Building afin d’appliquer le concept d’adaptabilité, en raison de ses avantages majeurs tant au niveau conceptuel que constructif. Différentes applications de l’approche Open Building, telles que le projet NEXT21 et le protocole KSI (Kikou support and Infill), offrent des exemples susceptibles de constituer d’efficaces lignes directrices pour la conception d’un espace supplétif. La faisabilité du modèle d’espace supplétif proposé est vérifiable et démontrable dans le monde réel. Les systèmes constructifs industrialisés sont en mesure de permettre le changement sans démolition car leurs joints mécaniques « à sec » rencontrent généralement les normes DfD (Design for Disassembly), non seulement en ce qui concerne l’espace supplétif mais pour l’ensemble du logement. / Demographics and lifestyles have changed considerably in the past few decades. These changes are bound to influence the design of housing and they notably include a series of emerging needs: additional spatial needs due to additional activities brought to the traditional housing premises. Planning for those emerging needs is the main theme of this thesis. In a typical single-family detached house, the basement is available to accommodate the spatial requirements for these emerging needs. However, such a provision does not typically exist in multi-family housing. This thesis proposes a specific additional space to accommodate these emerging needs: the supplementary space. Although such a space has not been explored in the literature, there are precedents for its application in multi-family floor planning. The objective of this study is to provide guidelines for the design and the integration of this supplementary space. It relies on the systems approach as the design-decision methodology due to its logic of deducting the solution from the analysis of the objective. Applying the systems approach means that all the criteria corresponding to the specific purpose of the supplementary space will be extrapolated from the objective. However, once the supplementary space is being used to deal with emerging needs, it will then introduce its own relevant criteria. This study will start with the criteria for designing a home office because this is the most demanding emerging needs activity. The criteria are organized as vectors of a generic model indicating how the supplementary space can be formulated. The model will target the workplace at home and subsequently offer solutions to them. This study focuses on the planning provisions dealing mainly with visual and spatial privacy. The overall outcome of the model is to suggest guidelines to incorporate the supplementary space within multi-family residential buildings, a feature not offered in traditional planning. The concept of adaptability is the key design strategy to accommodate change in architecture and housing, even more in the case of a supplementary space. Therefore, the supplementary space model will apply the concept of adaptability through the Open Building (OB) approach; elaborating more on the practical design and construction features. Different OB applications, such as the NEXT21 project and the KSI (Kikou Support and Infill) protocol in Japan, are examples that can be used as efficient guidelines to design a supplementary space. The feasibility of the supplementary space model can be validated and served in the real world. Industrialized building systems are capable of accommodating change without demolition as their dry mechanical joints are generally at meeting the DfD (design for disassembly) standards, not only for the supplementary space but also for the whole dwelling unit.
