National standard for pool area of residential buildings

Legal analysis: this standard is 10%-27%.

For ordinary houses below 7 floors, the pool area is generally between 10%- 15%. The shared area of the elevator building from the 7th floor to 15th floor is generally between15% and 22%. /kloc-buildings on floors 0/5 to 30 generally have multiple elevators, and their pool area is about 20% ~ 27%.

Legal basis: Measures for the Administration of Commercial Housing Sales

1) for multi-storey houses, the state clearly stipulates that the allocation rate of houses below 7 floors is 7%- 12%. The number of floors of a multi-storey building refers to a building with a mixed self-closing structure of about 6 floors, while the area of other common parts also includes half of the stairs and stairwells projected horizontally by the external wall and the service rooms (hot water exchange station, water pump room, power distribution room, etc.). ) to every household. Generally speaking, these will account for 13%- 18% of our building area. Indoor floor height is divided into indoor clear height (the distance from floor to ceiling) and indoor floor height (the distance from floor to the next floor). Generally speaking, the floor height is about 2.8 meters, and the indoor clear height of our building is between 2.65 meters and 2.7 meters. If the indoor clear height of our building exceeds 4.7 meters, we should calculate our indoor area according to two floors.

The housing allocation rate of the 7th floor-1 1 building is 10%- 16%. In general, the sharing rate of small high-rise buildings depends on the situation of each building. Because the pools of different small high-rise buildings are different. If there is no computer room underground and there are no shops and overhead buildings on the ground floor, the allocation coefficient of small and high-rise buildings is between 10%- 15%. For small high-rise households with elevators, the sharing coefficient is between 15%-20%. According to national regulations, elevators must be installed on floors above 7 floors. Therefore, the small and high floors are all within the scope of preparing elevators. The characteristic of this building is convenience, and it can also add a new height to our life.

2) For high-rise residential buildings, the sharing rate of floors 12-33 is 14%-24%. Why is the pool area of high-rise residential buildings the largest? Because, depending on the scale of the building, high-rise buildings are generally between 25 and 33 floors. Moreover, the stairs of high-rise residential buildings are the highest. Moreover, in high-rise buildings, in addition to the space occupied by elevators and elevator forerooms, the stairs of safe passages also occupy a lot of space, as well as "pipeline wells", "strong electric wells" and "weak electric wells", and many public facilities also occupy a lot of space. Therefore, for high-rise buildings, the higher the floor, the larger the pool area.

3) Villa residence: According to national regulations, the pool rate of villa residence is 1%-8%. Villa-style houses include underground floors and are single-family houses with up to three floors, including an indoor garage. Generally speaking, independent villas have no pool area, and conjoined villas have less pool area. The principle of sharing the public area of single-family villas is that there is a building structure connected with the building in one's own building, which only provides non-profit services to the residents of the building. These buildings do not meet this requirement, and the pool area cannot be calculated.
