Let's consider the end of the subway as a valid limit of the city. This border space, often witness of the failure of social politics of insertion, space colonized by the growing middle class youth, is also a space in constant transformation, of expansion, contraction, as a breathing lung.
This space talks about the past of the Urba, with its industrial ruins and its reminder of old urbanistic and social practices, for its customs and rituals. (sub)urbs offers an historical testimony of these borders in constant change. It eventually talks about its future real estate crisis, with its abandoned building works. This project shows us what we usually don't see, the "mustn't-see" of a city.
This is Beijing, but it could be Tokyo, Madrid, London, metropolises facing the issue of expansion, as well as real estate speculation generated by excessive demands of housing (or the artificial creation of this demand), and the quick change of epochs that sees life worlds from several distinct centuries in coexistence.
