How to pay attention to the construction area when buying a house

Generally, the purchase of a house is calculated according to the floor area and the shared area, not the usable area.

Buying a house is calculated according to the construction area, at least at present, the construction area of the house is used as the basis and standard for the sale of new commercial houses in the process of sales.

Buying a house is, of course, calculated according to the floor area. Because developers now sell houses, they generally sell houses according to the construction area, so buying a house is of course calculated according to the construction area.

Now buying a house is calculated according to the floor area, including the shared area, and the heating is also charged according to the floor area.

Buying a house is generally calculated based on the floor area. Regardless of the square meter of the building, it is calculated according to the floor area.

Nowadays, buying a house is calculated according to the floor area.

Including some areas of the corridor and the area of the veranda, they must be calculated and counted in the area.

In Chinese mainland, it is calculated according to the floor area, so the shared area is included.

Buying a house is generally bought and sold according to the floor area. At present, most places in the country are calculated by the construction area (including the common apportioned area of the building area in the suite), and some places use the construction area or usable area of the suite. There are 3 ways to calculate the sale of commercial housing:

Calculated by floor area; Calculated according to the floor area of the suite; Calculated by set. If you buy an existing house, the house price calculated in the three ways is the same, and if you buy an off-plan house, it is the fairest for the buyer according to the second option.

[Legal basis].

Article 27 of the Regulations on the Administration of Urban Real Estate Development and Operation shall sign a written contract for the sale of commercial housing. The contract shall specify the construction area and use area of the commercial house, the delivery date, the quality requirements, the property management method and the liability of both parties for breach of contract.

When buying a house, the precautions about the shared area are: do not blindly pursue a low public share, and the sales gimmick of "zero wax is suspicious of the public pool" is not credible; Pooled area = pooled coefficient * suite area, pooled coefficient = public use area of the whole building Suite area of the whole building; The shared area is calculated based on the horizontal projection area, and the sum of its construction area and the floor area in the suite constitutes the floor area of the commercial building.

[Legal basis].Article 8 of the Rules for the Calculation of the Sales Area of Commercial Housing and the Apportionment of the Common Building Area.

The common building area is composed of the following two parts:

1. The construction area of elevator shafts, stairwells, garbage chutes, substation rooms, equipment rooms, public foyers and aisles, basements, guard rooms on duty, and other public buildings and management rooms that serve the whole building;

2. Half of the horizontal projection area of the partition wall between the set (unit) and the common building space and the external wall (including the gable).

Usable area: The usable area can be literally understood as the area actually used by the householder. In technical terms, it refers to the sum of the net area of each floor of the building that is directly used for production or living.

Floor area: The building area is larger than the usable area, which is the area occupied by the wall on the basis of the usable area. In technical terms, it refers to the sum of the plane area of each floor measured above the outer horizontal plane of the outer wall of a residential building.

Calculation formula of construction area and usable area: construction area = building area in the suite + shared area shared area = construction area Pooled coefficient Pooled coefficient = total shared area of the building Total building construction area in the suite building area = usable area in the suite + wall area in the suite + balcony area Clear The calculation formula of the building area is one thing, but the developer usually marks the floor area of each unit type and the area within the set of feet on the floor plan. Therefore, it is more important for buyers to understand the difference between the floor area of the house and the area in the suite, so as not to overpay the house and not enjoy the space it deserves. The above is the relevant information about the difference between the usable area and the construction area, in fact, the usable area is the sum of the net area in the construction area that can be used or produced by people.
