How reasonable is the pool area of office buildings?

1. China has no specific regulations on the pool area of office buildings. The shared area of office buildings is generally between 10%- 15%, excluding underground equipment rooms, ground floor shops and ground floor overhead.

2. The shared area of office buildings with elevators is between 15%-20%.

3. The upper floor is relatively high, about 20%-25%.

4. There are double elevators and underground garages, and areas such as building width and public walkways are also divided in strict accordance with relevant standards. The pool housing area is controlled at around 25%.

1. Calculation method of shared area of office building: interior construction area = interior usable area+interior wall area+balcony area.

2. Sales area (also called Xing Tao construction area) = interior construction area+shared construction area (commonly known as "shared area"). Getting a room rate is an important goal of buying a house.

3. When calculating the house area, it is the building area, so the room rate is too low to afford; It's too high to be convenient. Because the higher the occupancy rate, the smaller the area of some public buildings, and the residents will feel depressed.

4. The common area of the office building includes: elevator shaft, equipment room, garbage chute, power distribution room, pipeline shaft, stairwell, guard room on duty, public hall, corridor, basement, etc. And the construction area of public and management buildings serving the whole building (calculated by horizontal projection area).

5.* * * The building area includes the partition wall between the suite and the public * * * building, and the external wall is half of the horizontal projection area.

What are the pool areas?

Apportionable public building area, that is, pool area:

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.

How to avoid the risk of excessive pool area of office buildings

The first measure: ask for pool data; When signing the purchase contract, let the developer show the data related to the calculation of the pool area, including the basic data such as the construction area of the whole building, the sum of the interior construction area and the construction area that should not be shared. You can also ask the developer to list the specific items of the shared public building area and the area of each item, so that the owners can calculate the shared area through data and clarify their rights and interests.

The second measure: obtaining relevant information; Owners have the right to inspect or hire lawyers to consult relevant documents of purchased real estate from design units, planning units, surveying and mapping departments and other institutions, such as final design drawings or final design plans, final area measurement reports, calculation methods of various data and their documents.

The third measure: stipulate the pool area in the house purchase contract. For the clauses in Article 3 and Annex 2 of the Commodity House Purchase and Sales Contract concerning the shared construction area between public housing and public housing, the buyer shall stipulate the number of shared construction area in the contract, and specify the specific location and area of shared construction area in Annex 2, Composition of Shared Construction Area between Public Housing and Public Housing. In particular, the more detailed the agreement, the better for the buyer. In case of disputes, buyers can protect their interests through contracts. Once a dispute occurs, the only choice is to sue the law to avoid wasting unnecessary manpower and energy. Of course, what we expect is that with the continuous improvement of laws, the continuous strengthening of government supervision and the continuous enhancement of developers' integrity awareness, the rights and interests of ordinary property buyers can be better protected.
