Abstract

Density in urban centers is the result of urban evolution. In extreme situations, density reaches levels detrimental to the quality of life.


This research analyses the physical causes of the decline in the functionality of urban systems growing along the usual lines of development. If town planning continues to seek the accepted geometric solutions, the drastic increase in density will constitute a mistake with foreseeable results.


Increased population density is achieved by duplication of floors; the drawback involved is the physical difficulty of duplication of public areas, e.g. parks, squares, roads, sidewalks, access to services. These functions are traditionally on ground level.


The research concludes that conceptual change is required in the approach to planning high density urban areas. An example is the coastal plain of Israel which will triple its population in one generation only.

The research studies proposed mega-structural solutions. Criteria were established for a comparative evaluation of the solutions offered. Also, urban solutions are presented and analyzed which, at certain points, have solved problems of density.


The research indicates that it is possible to crystallize a new approach to town planning which, at certain points, will turn two-dimensional planning into three-dimensional planning. Allocation of building plots will be three-dimensional to enable control of development of future higher layers, in contrast with present-day allocation which provides for floor duplication only. This would necessitate new legislation for the appropriate areas involved.
