If we buy an elevator car of 120 square meters, does the usable area of our house include the elevator area and corridor area?

Housing sales area is generally composed of interior construction area and pool area. However, because the calculation of pool area is complicated, it is also the focus of many problems and disputes in housing sales. In this issue, real estate experts will tell buyers, what parts does the pool area include? How to calculate? How big is the pool area to be reasonable?

The so-called pool area is the abbreviation of shared public construction area, which together with the interior construction area constitutes the construction area of commercial housing. At present, there are no clear laws and regulations on the treatment of pool area in China. Because of the fuzziness of pool area, it has become the focus of debate in the process of real estate transaction.

Reader Mr. Zhang introduced that he and his friend Ms. Ma bought a high-rise house with a building area of 73 square meters and 74 square meters respectively, but when he went to see Ms. Ma's house, he found that although her house was only bigger than his house 1 square meter, the living room and bedroom were obviously spacious. Upon inspection, the pool area of Mr. Zhang's house is 2 1.9 m2, and that of Ms. Ma's house is 13.32 m2. In this way, in the case of the same nominal price, the actual price is quite different. For ordinary property buyers, this is a problem that cannot be ignored. After all, they want to live in a bigger house with limited money.

For a long time, consumers have been accustomed to buying houses according to the construction area, which is equal to the interior construction area+pool area, which makes some unscrupulous developers "spread" in the process of housing sales under the legal coat of "pool area". However, due to the complexity and professionalism of the construction area calculation, it is difficult for buyers to know whether the area of the house they bought is enough and whether it has been mortgaged by the developer. Therefore, many property buyers have suffered such a "dumb loss".

How to distinguish the pool area?

At present, there is no law to limit the pool area in China, only the administrative regulations of the Ministry of Construction and the departmental documents of local governments have made principled provisions. At present, this policy is mainly implemented according to the national standard of People's Republic of China (PRC), Code for Property Survey, which came into effect on August 1 2000. According to the Code for Property Survey, the shared public building area is:

1. Lobby, public hall, corridor, aisle, elevator (building) hall, stairwell, elevator shaft, elevator machine room, garbage chute, pipeline shaft, water pump room, fire escape, power supply and distribution room, and guard room on duty, etc. , as well as public houses and property management houses serving the whole building.

2. The partition walls and external walls (including gables) between each set and the public building space are half of the projected area of the wall surface on the water surface.

The public building space that should not be included is:

1. Warehouse, motor vehicle garage, non-motor vehicle garage, driveway, etc. , as the basement of civil air defense engineering, has the independent use function of independent use space;

2. Houses sold by self-operated and self-used units;

3. The guard room and management (including property management) room serve multiple houses.

* * * The assessed construction area is the construction area of the whole building minus the sum of all sets of construction areas of the whole building, and then minus the construction area of the basement, carport, garage, gatehouse, management rooms serving multiple buildings and civil air defense works.

How to share the pool area?

The pool area is too large, which will inevitably reduce the cost performance of the house; Too small will affect the comfort of living. So how to share the pool area is reasonable?

At present, there is a concept that can be considered, that is, the sharing coefficient of housing. The calculation method of the housing allocation coefficient is: divide the total of the existing building area to be allocated by the total of the units participating in the allocation, and then multiply the units participating in the allocation by the allocation coefficient to get the allocation area of each house. Among them, the area to be shared should be measured by the surveying and mapping team of the property right department.

Generally speaking, the pool area of high-rise buildings is larger than that of multi-storey buildings. The allocation coefficient of high-rise buildings is generally between 0. 18-0.26, and that of multi-storey buildings is generally between 0. 1 1-0. 16. But every building, even every suite in a building is different, so the pool area of the house should be measured on the spot, and it should be determined according to the use function and related supporting conditions of the house, and there is no limit.

How to calculate the pool area

The calculation method of the pool area of residential buildings is:

Formula 2: shared area = construction area of each unit × sharing coefficient (sharing coefficient = * * * total construction area/total construction area of each unit participating in sharing)

Among them, the area to be shared should be measured on the spot by Shenyang Real Estate Surveying and Mapping Brigade.
