The average usable area of a house with a floor area of 90 square meters is 765㎡（63-82.8), the area minus the shared area is equal to the usable area (the building area in the suite), the shared ratio is usually 8%-30%, take 15% to calculate 90 - (90 * 15%) = 765㎡;The shared area is equal to the shared coefficient multiplied by the floor area of the suite; The built-up area of the suite is equal to the usable area of the suite plus the built-up area of the wall in the suite plus the floor area of the balcony; The common share factor is equal to the total common area divided by (the floor area of the unit multiplied by the total number of units).
Now there are houses of different sizes on the market, and when buying a house, the sales department staff will tell you what is the construction area of a suite, what is the actual area, and what is the shared area, so some people will ask how much is the usable area of the house with a construction area of 90 square meters?
1. How much is the usable area of a house with a construction area of 90 square meters?
Multi-layered: 765-82.8㎡
Small Upper Floor: 72-81
Upper floor: 63-765㎡
1.A house with a floor area of 90 square meters and a usable area of:
The formula for calculating the floor area is usually as follows: floor area = building area in the suite + common floor area. Among them, the construction area in the suite = the usable area in the suite + the wall area in the suite + the balcony construction area. The formula for calculating the usable area is: usable area = usable area in the set + wall area (if it is a wall used as a partition). The construction area (90) minus the shared area is equal to the usable area (the building area in the suite), usually the real estate certificate will indicate: how much the construction area, how much the shared area, the actual use of the area more.
2.Calculation of the relevant area of ordinary dwellings:
The shared area is equal to the shared coefficient multiplied by the floor area of the suite;
The built-up area of the suite is equal to the usable area of the suite plus the built-up area of the wall in the suite plus the floor area of the balcony;
The common share factor is equal to the total common area divided by (the floor area of the unit multiplied by the total number of units).
3.The general share ratio of ordinary dwellings:
Multi-layer: 8% to 15%.
Small high-rise: 10% to 20%.
High-rise: 15% to 30%.
4.Factors affecting the pooled area:
House type: One ladder and one household, one ladder and two households, one ladder and three households, point floors, and slab buildings in the same building are all different.
The area in the suite: the larger the house, the more the shared area, the smaller the house.
Public facilities: Some only have stairs, some have stairs and elevators, the shared area of these two floors is also different, the more public facilities, the larger the shared area.
Building size: The higher the stairs, the larger the pool.
2. What is the construction area?
The floor area refers to the unfolded area of the building, which is the area of each floor plane measured from the outer horizontal plane above the outer wall of the residential building. It represents the economic index of the size of a building, the construction area of each floor should be calculated according to the horizontal section of the outer wall above the leg, the construction area is calculated by the area plus the auxiliary area plus the structural area, it is also divided into the area of the suite, that is, the construction area of the suite, which is calculated by the area used in the suite plus the area of the wall in the suite plus the floor area of the balcony.
3. What is the usable area.
The usable area refers to the total usable area of the house in the unit, the total usable area of the sub-household, and the area actually used for living in the unit plan. Calculating the usable area can more intuitively see the use of the house, but when buying a house, it is not calculated with the usable area**Oh, the area that the developer tells you when buying a house is not the usable area, so when buying a house, you must ask the developer what the area is and what the area is.
4. What is the shared area?
The shared area refers to the construction area of the department that can be used by the owners of the whole building, including: garbage chutes, substation rooms, equipment rooms, public foyers, corridors, basements, elevator shafts, pipe shafts, stairwells, guard rooms on duty, etc., as well as the area of common buildings and management rooms that serve the whole building.
The above is the article shared with you today, how much is the usable area of a house with a construction area of 90 square meters, so not every 90-square-meter house will have the same usable area, and the usable area depends on the amount of the shared area to determine.
