Entre conflits et synergies: Renouvellement urbain et patrimonialisation

International audienceThe trabsformation of the existing urban fabric in projects of urban renewal is the product of a negociation process between urban actors with different interests. The choice to renew a particular urban area implies a bipolar reflection on the value of the existing urban fabric and its heritage potential on the one hand, and the actions and measures to tranform the urban fabric on the other. At first vew, processes of preservation and of renewal are diametrically opposed, which leads to the question whether the existing urban fabric should be preserved and valorized in order to transmit architectural an urban design heritage, or whether it should be erased for the construction of e modern urban fabric. This paper points the connections between the issues of urban renewal an preservation by analysing these processes in three types of urban fabrics in the main conurbations of France (the historical city centre, peri-central spaces, large-scale social housing estates). three types of representations (sentimental, economic, cultural) of the urban fabric are used to demonstrate that the relationship between renewal and preservation is not necessarily discordant but can be synergetic, according to the type of area under scrutiny and the extent to wich the representations of this area are shared.Renouvellement urbain et patrimoine : une relation étroite.
