The contemporary city, or rather, the contemporary cities: there are two or more cities that operate
simultaneously on the same site: the city of the soil, the subsoil, the above-soil. The less they touch, the less they contaminate, the better. The project can then perhaps act separately on these layers. Can outline a project of soil, which may also contain a project of the underground, through a modeling work, which includes, in addition to the carry-over of land, embankment, dam, terracing, including the excavation, the groove, the 'engraving, providing of covering it and live it over and inside, without necessarily identifying the lean or the sticking of buildings vertically above and within it. Or maybe you can outline a project of overground through the stretching of a plane terrain artificiel which also can be explored and inhabited and that are only a few points of direct contact with the underlying layer lifts. The layering in this way may not necessarily give as contamination: it has been in many cases in the past (especially in Rome) and sublime results, today maybe it's time to play on differences.
