The Metropolis is characterized by the overlapping of many distinct, mutually exclusive and divergent principles. This is what distinguishes it from the village, the town, the city district and from smaller and medium-size cities.... Eliminating poorly functioning and superfluous areas of the city will selectively reduce the urban pressure.... The enclaves thus released from a general urban anonymity will then create, as it were, liberated city islands, an urban archipelago in a natural green lagoon.... The idea of the City within the City accommodates the contemporary structure of society, which has developed more towards an individualized society with different needs, desires and ideas. The concept also incorporates the individualisation of the city and thus a dislike for a typical and for unification.
