New Floor Area Calculation Rules, Floor Area Calculation Rules

Calculation rules for building area: construction area, building area in the suite, shared area.

The construction area refers to the sum of the horizontal projection area of the periphery of each floor above the foot of the external wall (column) of the building, including balconies, corridors, basements, outdoor stairs, etc. The shared area refers to the area of public building space in the commercial housing that should be apportioned into the sales area in the sale of commercial housing.

Pooled area Pooled coefficient Floor area of the set. Pooling coefficient Total communal area (floor area of units, total number of units). Set of construction area, set of usable area, wall area.

Floor area:

When a buyer buys a house, the floor area generally refers to the sale area of the house. Specifically, it refers to the floor area formed by the building, including the outdoor balcony, awning, eaves corridor, outdoor corridor, basement, outdoor staircase, etc., attached to the building, and has a permanent building with a cover, a firm structure, and a floor height and above.

The construction area is also related to the collection of property fees and heating fees when buyers buy and move in, because these are charged according to the square meters of the construction area.

Calculation rules for building area: The construction area of a house refers to the calculation of the peripheral horizontal area and the horizontal projection area, including the calculation of the building area, the common construction area, the usable area, etc.

The floor area and usable area of the house are closely related to the buyer, and the buyer needs to have a certain understanding of the concept and calculation method of the building area.

The rules for calculating the floor area have the following general provisions

When calculating the area of the building building, it should be noted that: the first is that the building area is calculated according to the peripheral horizontal projection area of each floor above the outer wall (column) of the house, including balconies, corridors, basements, outdoor stairs, etc., and has a permanent building with a cover, a firm structure, and a floor height of more than meters (including meters, the same below).

Clause. 2. The common floor area of the house refers to the floor area jointly occupied or used by all property owners; Clause.

3. The usable area of the house refers to the total usable space area of the house, which is calculated according to the horizontal area of the interior wall of the house; Clause.

Fourth, the number of floors of the house refers to the natural number of floors of the house, generally calculated according to the indoor floor above.

Clause. 5. The level at which the house is located refers to the number of floors of the house in the building of the ownership unit. The subterranean level is represented by a negative number. Clause.

6. The area occupied by the structure of the house (such as walls and columns) includes the area occupied by the basement, but does not include the area occupied by the patio, balcony outside the wall, and the external staircase of the objective existence.

The rules for calculating the floor area are as follows:

1. Regardless of the height of a single-storey building, it is calculated according to the horizontal area of the outer wall above the foot of the building.

2. When the high span is a side span, its construction area is calculated according to the horizontal length of the outer surface of the gable at both ends above the leg multiplied by the horizontal width of the outer surface of the outer wall above the leg to the outer edge line of the mid-span column. When the high span is a middle span, the building area is calculated by multiplying the horizontal length between the outer surfaces of the gables above the leg by the horizontal width of the outer edge of the middle column.

3. The ground floor is calculated according to the horizontal projection area above the foot of the outer wall of the building, and the second floor and above are calculated according to the horizontal projection area of the outer wall of the building. When calculating the floor area of multi-storey buildings, attention should be paid to whether the outer edge of the external wall is consistent, and the first thing should be that when the outer edge of the external wall is inconsistent, the construction area should be calculated in layers.

Floor area:

The floor area refers to the sum of the horizontal area of each floor of the building, including the usable area, auxiliary area and structural area. The usable area refers to the net area directly used for production and living in the floor plan of the building, and the auxiliary area refers to the net area occupied by the floor plan of the building for auxiliary production or auxiliary life, such as the area occupied by stairs, walkways, toilets, and kitchens in residential buildings.

The sum of the usable area and the auxiliary area is called the effective area, and the structural area refers to the area occupied by the walls, columns and other structures in the plane of each floor of the building. Floor area is usually a conceptual term used in the field of real estate, which can more realistically reflect the construction scale, various economic and technical indicators and technical parameters of the building.
