The plot ratio refers to the gross density of the construction area, and refers to the ratio of the total construction area to the net land area of the residential area. An index used to measure the intensity of construction land. For developers, the plot ratio determines the proportion of land cost in the house. For residents, the floor area ratio is closely related to the living comfort. The lower the floor area ratio, the higher the comfort, and vice versa. In normal residential areas, the plot ratio of high-rise residential buildings is below 5, the plot ratio of multi-storey residential buildings should not be greater than 3, and the green space rate should not be less than 30%.

Second, what impact will the floor area ratio have on living?

1, high population density.

The plot ratio will affect the population density. If the density inside the community is high, there will be more people living in the community, which will have a certain impact on the fitness venue, children's activity area, elevators and fire exits in the community.

2. Security issues

The plot ratio is closely related to the safety of the community. When the plot ratio is large, there will be more people coming in and out of the community, and it will be less difficult for outsiders to get in. The security system of residential areas with high floor area ratio should have higher requirements. We should not only increase the density of monitoring equipment, but also ensure the safety of residents.

3. Internal planning issues

The plot ratio will affect the internal planning of the community, and the high plot ratio will affect the land utilization rate. When building a residential area, the floors of the house will be higher, and the proportion of green space will be reduced accordingly, which will affect the living environment and quality in the residential area. If the plot ratio is high, it will also lead to the situation that the building spacing in the community is too close and the parking space is insufficient.
