stratégie de densification, de diversification et de régénération des tissus pavillonnaires – BIMBY

Submission summary

In order to renew the ongoing ideas about the model of a sustainable city, the project proposes a research strategy based on the 3 following principles : To note, firstly that the ?urban fabric stock' currently consisting in all of the existing residential areas, is one of the most crucial work subjects : Because of its significant scale and scattering, that qualify, almost just by themselves, the whole urban spread phenomenon, which in itself, has been the most significant element of the evolution of cities over the last few decades. Because of its specific location in the centre of the aspirations and paradoxical rationales - of the inhabitants, whom, for most of them, long for individual housing forms, - of their elected representatives who mostly feel powerless in front of the global rationales responsible for the urban spread, - of the urban planners, whose community has scarcely ever taken any direct interest in the question of the evolution of residential areas. ` Because of the current moment in its life cycle, not only the durability and the evolution of the pattern of the residential areas but also the point of view of the inhabitants, indicate a growing discrepancy between, on one hand, the evolution of people's lifestyles at various stages in life, and on the other, the ability to fulfil their new needs and expectations. To consider, secondly, that most of the ?Sustainable cities' that could emerge from these residential areas, will result from continuous transformation and regeneration processes, from mutation processes, rather than from acts of ex nihilo creation : By processes of densification rather than by the creation of blocks of flats, as one can notice far too often for the construction of whole residential areas on former industrial wastelands, or on sites that had been preserved from any form of urbanisation. By processes of morphological, functional and social differentiation, rather than by planned densities, set social diversities or limited functional diversities. By processes of polarisation of economic activities, incorporation, redistribution, and relocation of the services, shops and facilities, by processes of gradual redevelopment of the transport networks rather than by the creation of artificial new central locations and the drawing of networks beforehand. To focus the research. Within the framework of this project, it will be done following a set of targeted phenomena, raising relevant issues, themselves drawing various hypotheses of precise answers : At the scale of individual plots of land. To study the opportunity and feasibility of making the capital available, represented by ownership over a detached house, by asking the owners to sell a part of their land which, once joined to corresponding part of the neighbour's land, would create a new building space. That is to say, building a house between two or next to existing houses, by dividing the land. At the scale of an area.. To apply this model to a wider range of possibilities of mutations by local iterations: division of houses into apartments, extensions and functional diversity, demolition and reconstruction, creation of new land etc. To determine to what extent an increase in the housing density would enable some shops and neighbourhood services to improve their profitability, to create a phenomenon of urban centralities, to increase the town's population, activities and income. At the scale of a town. To develop tools in order, not only to enable and increase that growth by successive stages, but also to keep it in control and direct it, so that it could be used for wider town-planning strategies of reorganising the urban territories, developing structured transportation networks, especially the ones offering alternative approaches to the use of cars. The BIMBY projects aspires to seize the opportunity to define the both complex and generic character of the theme of transformation of residential areas in order to build the theoretical and pragmatic groundwork of that truly systemic approach of urbanism. This approach is based on the creation of multi-faceted models, that recognise the generic character of the contemporary suburban urbanisation forms. This creation would be shared and co-developed by various professionals, and would be based on the principles of the systemic modelling relying on computer tools providing help to build strategies of transformation of the current urban landscapes.
