How to calculate the plot ratio of multi-storey residential quarters? Calculation method of plot ratio of residential quarters: plot ratio = above-ground construction area, residential construction land area. When the building is more than 8 meters, the total floor area of this floor will be doubled when the floor area ratio is estimated. For property buyers, the floor area ratio is directly related to the comfort of living. The plot ratio is relatively small, the building spacing may generally be relatively low, and the higher the living comfort of the community owners.

The common plot ratio type is 1, and the plot ratio is less than 0.3, which is also a high-grade villa project.

2. The plot ratio is 0.3~0.5. Generally, the natural environment of villa projects is ok, but it feels dense. If you cross some townhouses and single-family villas, you can get out of trouble.

3. The plot ratio is 0.5~0.8. If ordinary single-family villas and single-family villas are composed of 3-4 floors and some 5-storey duplex buildings, the taste of this project will become quite high.

4. If the plot ratio is 0.8~ 1.2, and they are all double-decked, the natural environment can definitely be called first-class. If mixed with low-rise buildings or even single-family villas, the natural environment can only be regarded as average.

5. Floor area ratio 1.2~ 1.5, which is a normal double-storey project with average natural environment. If it is a combination of two floors and small high-rise, the natural environment will be a big selling point of the product.

6. Floor area ratio 1.5~2.0, normal double-storey+small high-rise project.

7. The plot ratio is 2.0~2.5, which is a normal small high-rise project.

8. The plot ratio is 2.5~3.0, small high-rise building+Class II high-rise residential project (within 18 floor). At this time, if you want to be a small high-rise, the natural environment will be even worse.

9. The plot ratio is 3.0~6.0, which is a high-rise residential project (within 100m).

10, plot ratio above 6.0, skyscraper project.

Residential projects with high plot ratio represent that there are many houses built in the community, and dense houses will definitely produce dense population, which will eventually reduce the comfort of owners in the community. In addition, the high density of residents will also cause great work pressure on fitness places, children's outdoor sports areas, games and entertainment places, as well as home elevators and fire exits in houses. Frequent application will aggravate the aging of this equipment, so when we choose high-density residential quarters, we should clearly put forward higher requirements for this matter.

What is the floor factor? Living in a building (according to the general old house, that is, the sixth floor) also has dangerous security differences. To accurately measure the safety level of each floor, we can call this accurate measurement the accurate measurement of floor coefficient, and the safety level of each floor is called the floor coefficient.

Generally speaking, the third floor is the best, and the floor coefficient is1.15; The second floor, followed by the fourth floor, the floor coefficient is1.1; 1 floor, and the floor coefficient of the fifth floor is 1, which is equivalent to nothing; The floor coefficient of the 6th floor is 0.85, so the 6th floor has the highest cost performance. In fact, this basic principle can be understood as: generally speaking, the safety factor of relatively high floors is lower, and the more middle floors, the higher the floor factor.
