The plot ratio and building density are stipulated, not the smaller the better, nor the larger the better. Only those that meet the relevant regulations are good.

Building density refers to the coverage rate of buildings, specifically refers to the ratio (%) of the total basement area of all buildings within the project land area to the planned construction land area, which can reflect the vacant land rate and building density within a certain land area.

Building density = area of the first floor of the building/planned land area. For example, a piece of land is 10000 square meters, of which the building area is 3000 square meters, and the building density of this land is 3000/ 10000=30%. Generally, the building density will not exceed 40%-50%, and roads, greening, squares, parking lots, etc. need to be reserved for land in some areas.

Extended data

Building density refers to the total basement area of the building/planned construction land area. For example, a piece of land is 10000 square meters, of which the above-ground building area is 3000 square meters, and the building density of this land is 3000/ 10000=30%. Generally, the building density will not exceed 40%-50%, and roads, greening, squares, parking lots, etc. need to be reserved for land in some areas.

Building density is different from building floor area ratio. Compared with the same building plot, the building density is the area occupancy rate of the building, and the building floor area ratio is the use space of the building.
