Internal Structure
There was a popular mistake in city planning, especially in new town planning. Simple and static divisions were given to define a city in functional regions, however, the nature of a city is complicated and dynamic. Consequently this deviation caused anti-site defects in urban development, for instance, the dead city phenomenon of city central area and the traffic indigestion in commuting time. This unwise tradition in planning of horizontal city was also inherited in early design of vertical city. The first hyper tower proposed by Theodore Garrett was simply “divided vertically in four functional sectors with industry in the bottom, offices in the second quarter, living in the third and a hotel in the fourth.” (Rem Koolhaas, 1978) This similar flaw limited the development of vertical city as well. In contrast, hyper tower in 2090 is an open structure which is more agreed with the essence of city, a dynamic system. It mainly embodied in three aspects, more comprehensive function distribution in social layer, new separation in pedestrians and vehicles in traffic layer, and exchangeable dwelling capsule in residential layer.
