The analysis of the overall design process in low-cost housing is very important in trying to utilize efficiently available information, and general concepts to provide several alternatives, for a given value system so that the needs are satisfied with the optimal utilization of resources. Unless the problem is seen as a whole with all the complex interactions between the elements, the so-called economical low-cost housing solutions may be sub-optimal in a general sense. The present approaches are extremely piecemeal in approach and scope, and the problem definition and analysis of needs are not general enough and independent of available alternate solutions. The proposed approach helps the generation of and identification of innovative solutions. Ekistics gives a good base to achieve technical-social-economic-environmental interaction.
