For the first time in history more than half the world’s population live in cities. This demographic fact was anticipated since the whole of modern development has been heading towards an urbanised society and a civilization of cities. The influence which academic architectural culture, the privilege of ‘extraordinary’ places, had on the development of the civilization of cities was limited. On the other hand construction, which could be described as an ephemeral culture, mostly belongs to the periphery and does not make the essence of city development.
