What is the national control standard of plot ratio?

National control standard for floor area ratio: the floor area ratio of buildings below seven floors shall not exceed 1.6, that of buildings from seven to ten floors shall not exceed 2.0, and that of buildings above1/kloc-0 shall not exceed 3.5. "The plot ratio refers to the ratio of the total floor area above ground to the net land area of a community. Also known as gross density of building area. In a good residential area, the plot ratio of high-rise residential buildings should not exceed 5, that of multi-storey residential buildings should not exceed 3, and that of green space should not be less than 30%. However, due to the limitation of land cost, not all projects can be done.

Generally speaking, it refers to the ratio of the total construction area of various buildings on the ground to the base area within a certain base range. The underground volume ratio can be calculated according to the needs of planning and management. In fact, it has always been stipulated by the local government itself. Whether the basement is the floor area ratio and whether the underground commercial building is the floor area ratio has been well explored. Not counting the plot ratio is to save land and encourage the development of underground space. Calculate the floor area ratio in order to standardize the real estate market and prevent loopholes for bad developers. The plot ratio will be directly related to the size of construction land.

It is built on a plot of 100 square meter, with a floor area of 100 square meter on each floor, with a total floor area of 200 square meters and a plot ratio of 2.0; If three floors are built, the construction area of each floor is 50 square meters, the total construction area is 150 square meters, the floor area ratio is 1.5, and so on.

The plot ratio represents the allowable building capacity per unit land area in a specific "plot". Parcel is the basic unit of cadastral management. It is a piece of land with clear boundaries and ownership on the earth's surface, and its area does not include public roads, public green spaces, large municipal and public facilities. The plot ratio can only reflect the specific intensity of land use by referring to the plot ratio of "parcels", and the parcels are comparable.
