The development in modern cities has resulted in the emergence of single-use areas, dictated by the narrow monetary interests of bankers and developers. Such areas consist of a collection of glossy buildings unrelated to the locality. There is no provision for street-related activity and the buildings do not address the street. There is therefore a form of no-man's-land which is exceedingly alienating to anybody who has no purpose relating to that single use. Complexity of use and need, including the role of the ordinary citizen in the daily economic, cultural, social and political life of the city, has been increasingly neglected.
