How to calculate the floor area of the house, for example

How should the area of the house be calculated?

Calculation skills

1. The construction area of the house should be calculated according to the sum of the horizontal area of the periphery of the natural layer exterior wall structure, the construction area of the house is usually the grade area of the real estate certificate, usually the purchase price and property fee are calculated according to the construction area of the house, the construction area of the house = the construction area of the suite + the apportioned common area.

2. The actual usable area of the house refers to the sum of the net area of each room that we can actually use, excluding the area of interior walls, exterior walls, balconies, etc., so the usable area = the construction area of the suite - the area of the wall inside the suite - the area of the balcony.

The usable area of the house mainly includes:

1. The sum of the space area of the bedroom, aisle, living room, kitchen, bathroom, storage room, closet and so on.

2. The internal stairs of the house, such as the stairs of the jump, shall be included in the usable area according to the sum of the area of the natural floors.

3. Chimneys, ventilation pipes, and pipe wells excluding structures all belong to the usable area.

4. The thickness of the interior wall decoration of the house also needs to be included in the usable area.

The state stipulates that there is a certain ratio, and generally speaking, the housing efficiency of multi-storey buildings is higher than that of high-rise buildings.

The construction area includes the shared area, the multi-storey room rate is generally about 82%, the difference between the construction area and the use area is about 18%, the high-rise is about 75%, the difference between the construction area and the use area is about 25%, because the high-rise elevator and the hall area on the first floor are shared, so the shared area is larger.

For example, you can multiply the floor area by the housing rate, and you can calculate your usable area, your house area is 113 square meters, if it is a multi-storey usable area of 93 square meters, if it is a high-rise area, it is about 84 square meters.

Answer: The actual area of the house is the area that the owner really uses, so the actual area of the house = the floor area of the house - the area of the wall in the suite - the area of the balcony. The construction area is the area occupied by the wall on the basis of the actual area, and the construction area = the construction area in the suite + the apportioned common area.

Question: Why does the merchant say that the actual usable area includes the public pool?

She said that the elevators were also used [covering her face] how to tell the difference.

But when I buy a house now, I buy the floor area.

Building area = usable area + shared area.

Therefore, the pooled area is generally counted together now. That's why he said that the elevator is also counted in it.

Question: There is no actual usable area as expressly stated in that article.

The question was asked because we asked what the actual usable area was, but it wasn't that much, but the contract was smaller than the actual one, and she said that the tax education was small.

Because we asked what the actual usable area was, but there was not that much, but the contract was smaller than the actual one, and she said that the tax education was small.

Now I don't admit it.

He doesn't admit it, does he?

If you sign a contract, you will act according to the contract.

This is the kind of thing that can sue him.

For ordinary families, it may take a lifetime of savings to buy a house, so they will be very cautious in everything they do to buy a house, everyone knows that buying a house is calculated according to the area of the house, so the area is a matter of great concern to everyone, so how to calculate the floor area of the house? Let's take a look.

1. How to calculate the floor area of the house.

1. The construction area refers to the horizontal projection area of each floor above the legging, generally less than 90 square meters, and the total horizontal projection area of various balconies shall not be greater than 12 square meters. For units with a floor area of 90 to 140 square meters, the total horizontal projection area of various balconies shall not be greater than 15 square meters. For units with a floor area of 140 square meters, the total horizontal projection area of various balconies shall not be greater than 18 square meters.

2. The depth of the inner balcony and composite balcony shall not be greater than half of 1.5 meters, which shall be included in the construction area. All items exceeding 1.5 meters are included in the gross floor area. When the depth of the unenclosed balcony is not more than 0.6 meters, it is not included in the construction area.

When it is greater than 0.6, half of the floor area is calculated.

3. If there are two or more households in one ladder, the part of the public wall shall be evenly distributed according to the household. There is also the shared area, which is generally stairwells, elevators, and public corridor lights. To put it simply, if the floor area of the first floor is 200 square meters, and the house type is exactly the same for two households, then the construction area of a house is 100 square meters, including the shared area.

2. Calculation range of construction area.

When calculating the area of the house, it is necessary to calculate the horizontal projection area of the periphery of each floor above the footline of the exterior wall of the house. This table includes balconies, basements, outdoor staircases, verandahs, etc. If it is a permanent building with a superstructure, a firm structure, and a floor height of more than 2.2 meters.

The area occupied by the structure of the house includes the area of the basement, but the area occupied by the patio, outside the wall, balcony, etc. is not included.

The floor area of the house = the floor area of the suite + the shared area. Pooled area = pooled coefficient * built-up area in the suite. Pooling coefficient = total common sharing area (floor area in the suite * total number of units). The construction area in the suite = the usable area in the suite + the wall area.

Scope and method of calculating the floor area: Quiver and Hui.

1. The building area of the house is calculated according to the outer horizontal area of the structure above the foot of the outer wall, and the construction area of the multi-storey house is calculated according to the sum of the construction area of each floor.

2. The indoor net height of false floors, loft (dark) floors and inclined structure roofs is above (including the part, calculated according to its projection area.

3. The ceiling height of the house is above (including the stairwell and elevator machine room, calculated according to the peripheral horizontal projection area of the structure.

4. In the ground floor, mezzanine, basement and independently built bicycle room and garage, the floor height is above (, calculated according to the peripheral horizontal projection area of the structure.

6. For houses with expansion joints, if they are connected with the interior, the expansion joints shall be calculated as the construction area.

7. The outdoor staircase with a roof is calculated according to the horizontal projection area of each floor.

8. Floors, fully enclosed balconies and corridors are calculated according to the peripheral horizontal projection area of the structure.

9. The part of the void floor in the duplex and duplex building, regardless of the height of the floor, is calculated as the floor area. Stairwells are not recognized as overhang floors.

How to calculate the range of floor area.

1. Regardless of its height, a single-storey building is calculated as one floor, and its construction area is calculated according to the peripheral horizontal area above the foot of the external wall of the building. Single-storey dwellings with partial floors (e.g. attics) should also be counted as gross floor area.

2. The construction area of a multi-storey or high-rise residential building is calculated according to the sum of the construction area of each floor, and the ground floor is calculated according to the outer horizontal area above the outer wall of the building, and the second floor or above is calculated according to the outer horizontal area of the external wall.

3. The construction area of basements, semi-basements, etc. and the corresponding entrances and exits shall be calculated according to the horizontal area of the outer wall of its upper mouth (excluding the lighting well, moisture-proof layer and its protective wall).

4. Use the deep foundation to make use of the underground overhead layer, and if the floor height exceeds one meter, the construction area shall be calculated according to half of the horizontal area of the periphery of the overhead layer.

5. The passage through the building, the entrance hall and hall in the building, regardless of the height, are calculated as one floor area. The construction area of the corridor in the hall is calculated according to its horizontal projection area.

6. The construction area of elevator shafts, lifting wells, garbage chutes, pipeline wells and attached wall chimneys are calculated according to the natural layer of the building.
