户型是住宅设计的依据之一,它关系到住宅的合理使用和分配。一般认为,户型种类多一点,分配比较灵活,更能切合实际需要,似乎这是没有疑问的。然而这种方法的合理性要得到实现,必须做到当居住家庭人口数量及构成变动时立即调整住房,显然这是脱离实际的。实际上,一个家庭分到住房后,在相当长的一段时间内是固定的, House type is one of the basis for residential design, it is related to the rational use and distribution of housing. It is generally believed that there are more types of households and more flexible allocations, which can better meet actual needs. It seems that there is no doubt about this. However, the rationality of this method must be realized. It is necessary to adjust the housing immediately when the number and composition of the household population changes. Obviously this is not practical. In fact, after a family is allocated to housing, it is fixed for a long period of time.
