How are the plot ratio and greening rate determined? The plot ratio refers to the area ratio of the building area to the construction land in a certain piece of land. For example, a plot with a range of 100 square meters, with a total construction area of 100 square meters on each floor and two floors, with a plot ratio of 200m2, belongs to non-ordinary housing. If the plot ratio of a residential area exceeds 5, such a residential area is very uninhabitable.

The greening rate refers to the proportion of the green area within the planned construction land of new projects to the total planned construction land area. If the green coverage rate of the community is large, the living environment and air index of the community are also good. The greening rate of new and old residential areas is really different. If it is a newly created community, the greening rate needs to be around 30%. If it is an old community, the greening rate should be kept at around 25%.

The factors that affect the plot ratio are closely related to the total construction area of all residential quarters and their owners, and the greening rate is closely related to the public landscaping sites and their vegetation coverage rate of all residential quarters. Both of them are directly related to the feeling of living in the community, its comfort, the living environment of the community and its overall three-dimensional sense. The smaller the plot ratio, the more the total area of a specific residential area, and the better the quality. These are closely related, so the quality of a community, the greening rate and its floor area ratio are very important.

For ordinary residential areas, if the plot ratio is too high or the greening rate is too low, most residential areas will have some problems in terms of living safety factor and comfort. The plot ratio of high-rise residential buildings is no more than 3 and that of high-rise buildings is no more than 5, which is very suitable for residential areas with strong living environment.

What is the floor area ratio of the house to be comfortable? The plot ratio is generally stipulated by the government departments, which is 0.2 ~ 0.5 for independent villas, 0.4 ~ 0.7 for single-family villas, 0.8 ~ 1.2 for high-rise residential buildings below 6 floors, 1 1 small high-rise residential buildings with one floor 1.5 ~ 2.0,/kloc-0.

Does the high floor area ratio have any impact? 1, high population density:

Although the floor area ratio refers to the ratio of the total construction area to the occupied area, the increase or decrease of the total construction area will affect the resident population. Therefore, from the floor area ratio, buyers can determine the relative population density of a community. High volume ratio housing will inevitably produce a dense population. If the population is too large, the living comfort of the community will be reduced and the privacy will not be so good. Therefore, property buyers should mainly observe this point when purchasing high-density residential areas.

2. The overall planning of internal structure is poor:

Most of the total area of plots with strong plot ratio is used for building, while the total area used by other supporting facilities providers is very small, such as green space and public places. Less landscaping and small public activities will endanger the environment and quality of residential areas. Another estimate is that the distance between buildings is too close and the roads in the community are narrow, which will adversely affect the lighting and natural ventilation conditions of houses.

3. Smart security is more difficult:

Under the premise of large floor area ratio, there will be more residents, so there will be more people entering and leaving the community at ordinary times, and the probability of migrant workers infiltrating into it will be greater, which will enhance the security risk. Therefore, it is difficult to manage the residential area with large plot ratio, especially in the aspect of intelligent security, which puts forward higher requirements for the security monitoring system of high plot ratio houses and is also a kind of training for property companies, which have to deploy more inspectors to ensure the safety of residents.
