Housing and Construction: Policies and Constraints مقاله

خلاصه ماشینی:

Abstract: In this article, common construction methods in large-scale housing provision projects are investigated from three interrelated perspectives, including the choice of building materials (Choice of Meterials), land use and dependent spatial arrangements (Land Use and dependent spatial Arrangements), and cost (Cost), in order to find a suitable pattern for providing housing for the increasing population of urban areas. C- The difficulty of applying regulations and design due to the gradual and heterogeneous nature of constructions; the above, alongside the increase in urban land prices, has caused a tendency toward increasing building densities or more high-rise development, the most important goal of which is to reduce urban surfaces and land needs and resolve the problems mentioned above. In contrast to these strengths, high-rise development has major weaknesses has, which explaining these points will probably be able to convince us that, while accepting the inevitability of implementing this policy in large cities, different policies are necessary to solve the housing problem in small and medium-sized urban areas, which will be referred to in the next section of the article. Studies conducted indicate that the foreign exchange requirement of these constructions accounts for 25-50 percent of the production cost, whereas countries like Japan, Singapore, and Hong Kong, due to prioritizing the provision of housing that is consistent with their level of economic development, have been able to build an average of 5-10 housing units per thousand people annually.
