一个好的住宅设计,不仅住宅个体本身应该户型合理、房间安排得当,而且应该有利于规划中节约住宅建设用地。一般说来,在每户建筑面积相同的前提下,减少每户面宽(或称加大房屋进深),不单意味着由于减少建筑物的外墙面而节省了室外道路、管网及住宅本身的采暖、土建费用,更为重要的是大大节约了住宅的建设用地。 A good residential design, not only the individual housing itself should be reasonable, the room is properly arranged, but also should be conducive to the planning of saving residential construction land. In general, under the premise that each household has the same building area, reducing the width of each household (or increasing the depth of housing) not only means that the outdoor roads, pipe network and the house itself are saved due to the reduction of the external wall of the building. The heating and civil construction costs, more importantly, are significant savings in residential construction land.
