When we buy a house, we often hear a word that is “floor area ratio”. For this word, many people are not particularly familiar with it. In fact, it plays a very important role in our living environment. So what does floor area ratio really mean? Is the floor area ratio good or small?
I. What is the concept of floor area ratio
The so-called “floor area ratio” refers to the ratio of the total building area of a residential area to the land area. For developers, floor area ratio determines the proportion of land price cost in the housing, while for residents, floor area ratio directly relates to the comfort of living. Green space rate is also a concept. The higher the green space ratio, the lower the floor area ratio, the lower the building density in general, the less space for the developer to recover the funds, and the more comfortable the occupants. These two ratios determine whether the project is designed from the perspective of people’s housing needs or purely from the perspective of making money. For a community with a good living environment, the floor area ratio of high-rise residential buildings should not exceed 5, multi-storey residential buildings should not exceed 3, and the green area ratio should not be less than 30%. But limited by the cost of land, not all projects can be done.
Second, the popular explanation of floor area ratio
Plot ratio: the ratio of the total building area within the project land area to the total project land area.
Floor area ratio calculation formula:
Plot ratio = total floor area ÷ total land area
When the height of the building is more than 8 meters, the floor area of the floor should be doubled in the calculation of floor area ratio.
The lower the floor area ratio is, the higher the comfort level of residents will be; otherwise, the lower the comfort level will be.
In the final analysis is the relationship between the number of households in the community, the number of people and the area of the community. Of course, the fewer households, the fewer people, the bigger the area, the more comfortable.
Three, how much floor area ratio is appropriate?
Generally, the floor area ratio of residential buildings has been determined in the land auction. Only what kind of products are suitable for what floor area ratio. The following provides the corresponding floor area ratio values of various buildings for your reference.
1. Plot ratio is lower than 0.3, which is a very high-grade single-family villa project.
2. Plot ratio is 0.3~0.5. The environment of ordinary single-family villa projects is OK, but it will feel a little dense. If interspersed into part of the double villa, townhouse, you can solve this problem.
3, floor area ratio 0.5~0.8, general double, townhouse, if combined into 3~4 floors, local 5 floors in the building, the grade of this project will be quite high.
4, plot ratio 0.8~1.2, all are multi-layer, then the environment can be called *. If it is mixed with low-rise or even townhouses, the environment is mediocre by comparison.
5, floor area ratio 1.2~1.5, normal like multi-layer projects, the environment will be general. If it’s a combination of multistory and small high-rise, the environment can be a big selling point.
6. Floor area ratio 1.5~2.0, normal multi-storey + small high-rise projects.
7. Floor area ratio 2.0~2.5, normal small high-rise projects.
8. Floor area ratio of 2.5~3.0, small high-rise + second-class high-rise projects (within 18 floors). At this point if all do small high-level, the environment will be very poor.
9. Floor area ratio 3.0~6.0, high-rise projects (building height less than 100 meters).
10. Skyscraper projects with floor area ratio above 6.0.
In short, the larger the floor area ratio is, the more comfortable people’s living conditions will be. If it is too small, the living environment will be affected and people will feel crowded. Therefore, for us house buyers, the floor area ratio directly affects the living environment. We must pay attention to this knowledge when buying a house. The above is a small series for you to collect the relevant information about what is the floor area ratio, I hope to help you.
