The usable area is small, the shared area is large, and the construction area is large, how to calcu

Is it a pre-sale contract or a purchase contract that you signed when you bought it? If it is a pre-sale contract, that is, the developer has obtained the pre-sale license of commercial housing but has not yet obtained the real estate right certificate and the large property certificate, so the area of the house is the first area, and the measured area will not be available until the property certificate comes down.

If you buy a house with a pre-sale area, the area is surveyed and mapped when you buy it, and the last measurement is carried out when you hand over the house. So there is an area to make up the difference.

The contract states: [Handling of Area Differences].

Area difference ratio (actual floor area of the suite, floor area of the suite agreed in the contract) Floor area of the suite agreed in the contract 100

If the real estate is calculated according to the floor area of the suite, if there is a difference between the actual floor area of the real estate delivered by the seller and the floor area of the suite agreed in Article 3 of this contract, it shall be handled in the following ways:

1. The construction area of the suite agreed in this contract is less than 300 square meters (inclusive).

1) If the difference value is within (including this number), the buyer and the seller shall not refund or make up for each other.

2) If the difference value is above (excluding the number) to less than 3% (including the number): if the area is exceeded, the excess area shall be regarded as a free gift from the seller; If the area is insufficient, the seller shall refund the price of the insufficient part to the buyer twice (after deducting the error).

3) If the difference value is more than 3% (excluding this number), the buyer has the right to terminate the contract. If the buyer terminates the contract, the seller shall refund the purchase price paid by the buyer within 10 days and pay the interest calculated according to the loan interest rate for the same period announced by the People's Bank of China, and pay liquidated damages to the buyer at the rate of 10% of the total price of the real estate. If the buyer does not terminate this contract, it shall be executed in accordance with subparagraph (2) of this paragraph.

Question 1: The floor area is the total area of the house.

Knowing the floor area and common area of the house, how to calculate the usable area?

The floor area of the house refers to the sum of the projection area of all building components of the house in the horizontal direction of the bar, excluding the thickness of the exterior walls. The shared area refers to the area of the common parts of the house, such as corridors, stairwells, elevator halls, hallways, etc., which need to be enjoyed and maintained by all owners of the house. Then the saleable area can be calculated by the following formula:

Saleable Area = Floor Area - Shared AreaFor example, if the floor area of a house is 100 square meters and the shared area is 20 square meters, the saleable area is: Saleable area = 100 square meters - 20 square meters = 80 square meters It should be noted that the saleable area refers to the internal area of the house that the owner can actually use, including the area of private use areas such as living room, bedroom, kitchen, bathroom, etc.

If the shared area of the house you buy is too large, look at the structure of the house in advance, sign a contract with the developer and keep it well, and leave a copy. You can also consult a lawyer to see if the developer is committing fraud or fraud. Then find a formal unit of measurement and issue a certificate after measurement, which is kept as evidence.

Check whether the house has been changed by other questions and list them together. Ask to check out, or change rooms, and make up the difference and loss at the same time. The shared area of the house should be measured on the spot, and determined according to the use function of the house and related supporting conditions.

Buyers must pay attention to the shared area of the purchased house before buying a house, and those who are not satisfied should give up the purchase as soon as possible. Generally, the size of the shared area is closely related to the size of the house, the building form, and the size of the common parts. Moreover, the size of the shared area varies according to the different structure of the house and the nature of use, and no department in the state has made an upper limit.

If the service functions of a community are more comprehensive and the supporting facilities are more complete, such as a large public foyer, elevator aisle, complete equipment room, etc., the public sharing coefficient will be higher. For more information about how to deal with the excessive shared area, enter to see more internal stuffiness.

Summary. If the owner finds that the apportioned area of the house has become larger when the house is taken over, and the developer requires the owner to pay, the owner can adopt different pricing methods and specific solutions according to the agreement between the parties to the sale and purchase contract.

2. If the area error exceeds 3% of the absolute value, and the buyer's request to terminate the contract and return the purchase price and interest paid, it shall be supported. If the buyer agrees to continue to perform the contract, and the actual area of the house is greater than the area agreed in the contract, the buyer shall make up the price of the house price within 3% (including 3%) of the area error ratio within 3% of the agreement, and the seller shall bear the part of the house price with the area error ratio exceeding 3%, and the ownership shall belong to the buyer.

What should I do if the shared area is large and the usable area is small when the total area remains unchanged when the house is delivered.

Hello dear<>

Please wait a moment, we have seen your question about the tour of the hall, and we are quickly sorting out the information for you, and we will send your answer to the little master immediately. Thank you for your support, recognize my service, and remember to give a thumbs up<>

<> grind line! If the owner finds that the apportioned area of the house has become larger when the house is taken over, and the developer requires the owner to pay, the owner can adopt different pricing methods and specific solutions according to the agreement between the parties to the sales contract.

2. If the area error exceeds 3% of the absolute value, and the buyer's request for the cancellation of the Hezen Shoutong and the return of the purchase price and interest paid shall be supported. If the buyer agrees to continue to perform the contract, and the actual area of the house is greater than the area agreed in the contract, the buyer shall make up the price of the house price within 3% (including 3%) of the area error ratio, and the seller shall bear the part of the house price with the area error ratio exceeding 3%, and the ownership shall belong to the buyer.

The sales area of the house is generally composed of the floor area of the suite and the shared area. However, because the calculation of the shared area is more complicated, it is also the focus of many cats and disputes in the purchase and sale of houses. In this issue, the property experts will tell the buyers, what exactly does the shared area include?

How is it calculated? How big is the pooled area? The shared area is no stranger to buyers, and in layman's terms, it is to share the common use area.

The shared area changes according to the changes in the house type, the area in the suite, the public facilities, the building scale, etc., so the calculation of the shared area of each building is divided into the following ways because of its different design and function: generally it should be stipulated in the calculation rules of the construction area, and the total area is calculated according to the size of the design drawings, minus the actual total area of the household, and the remainder is apportioned according to the actual area of the household, and the actual area of these apportionments is the shared area.

The shared area has been criticized by buyers, but we can only treat the shared area with helplessness. Since everyone is so disdainful of the public stall, it is so incomprehensible. The following Lao J will explain how the shared area is calculated based on his actual work experience.

Compare the situation of your own community in detail, you can probably get the amount of your own area, and you can know where the difference is by comparing the published amount. If there is an objection, the measurement review can be carried out through the petition or litigation channel, and it is best to apply collectively because of the higher cost.

The staircase room below 7 floors is 7%-12%, and the multi-storey residential buildings with 7 floors to 11 floors have elevators, so the sharing coefficient is generally 10-15%, and 12 and 33 floors are located, because the residential buildings above 10 floors have the requirements of fire protection regulations, and fire escapes should be set up, so the sharing rate is 15 -30.

However, even if the owner has all the detailed drawings, it is still impossible to calculate the data such as the pooling coefficient and the pooling area. Because the calculation method and complexity are beyond the grasp of non-specialists.

The shared area is generally 12%-18%.

The shared area of small high-rise buildings is about 18%-24%, and the shared area of high-rise buildings is generally 25%-30%.

The shared area is the part of the main body minus the area in the suite, including: door bucket, hallway, lobby, corridor, corridor, front room, staircase, elevator, roof room, elevator machine room, real room, exterior wall, insulation, etc.

The shared area is the abbreviation of the shared construction area, and the common sharing coefficient of ordinary multi-storey residential buildings is about 10%-15% when there are no shops underground and the ground floor is overhead; The share coefficient of small high-rise residential buildings is about 15%-20%; For high-rise buildings, it is about 20%-25%.

This depends on the usable area of the building to be purchased, and this individual difference will be different. The larger the number of squares purchased, the larger the shared area, and conversely, if the purchased house is smaller, then the shared area will also decrease. However, the magnitude of the swelling generally fluctuates in the range of 20% to 25%.

About 10%, because the shared area of the house I bought is about that much.

More than 36 percent of the resettlement housing here is located in Wangjiawan Resettlement Community, Xinyang City, Henan Province.

There are rules to follow in the calculation of the shared area.

1) The contents of the common construction area include: elevator shafts, pipe shafts, stairwells, garbage chutes, substation rooms, equipment rooms, public foyers, aisles, basements, guard rooms on duty, etc. and the floor area of the public building management building that serves the whole building, as well as the calculation of the horizontal projection area.

The common floor area also includes the partition wall between the set and the public building, and the floor area of half of the horizontal projection area of the exterior wall (including the gable).

Independently used basements, carports, garages, guardhouses serving multiple buildings, management rooms, and basements used as civil air defense projects are not included in the common construction area.

2) the calculation method of the common floor area; The floor area of the whole building is deducted from the sum of the floor area of each set of the whole building, and the construction area of the basement, carport, garage, guardhouse serving multiple buildings, management room, and civil air defense works that have been used independently. This is the total floor area of the entire building.

3) Apportionment method of common floor area.

Residential buildings are based on the following calculation formula:

The total floor area of the building.

Shared area of each suite - x area of each suite.

The total area of the building.

The calculation of the builder is generally not wrong, the housing rate varies greatly from property to property, and you may feel that the low housing rate is a loss, in fact, if it is a second-hand house in the future, it is also calculated according to the construction area, and it will not suffer significantly.

If you have any questions, please feel free to ask.

Because it is an impact upgrade, if you are satisfied with this answer, please give one, thank you!

The problem of the public sharing of the house is generally determined by the flexibility of the developer, generally the public share of the tower is large, the public share of the slab building is small, and the shared area with an elevator will also increase, if you want to share a small public area, it is recommended to buy a slab building with a total number of floors not exceeding 7 floors, and the public sharing will be relatively small.

When buying a house, you will encounter the cover of the shared area, but the shared area needs to be within a certain range to ensure normal living in the later stage, so you should ask clearly before buying a house. So how to deal with the pool area that is too large, and how much the pool area is appropriate, do you understand? Now let's take a look.

1. How to deal with the large shared area.

If the shared area is too large, the steps are as follows: Keep the "purchase contract" and keep a copy; Ask a local lawyer to see if the developer is fraudulent; Let a professional surveying company issue a certificate after measurement; Check the house for other problems; Negotiate with the developer, check out or change the house, and pay the difference.

Second, the shared area is appropriate.

1. Multi-storey Juesui residence.

The multi-storey residential buildings we call are usually buildings with less than six floors, and the shared rate is generally between 7% and 12%, and the shared area includes power distribution rooms, stairs, property management rooms, etc. Most of the multi-storey houses do not have elevators, so the share rate will be relatively small, if the elevator is installed, it will be appropriately increased.

2. Small high-rise buildings.

Small high-rise buildings, mainly referring to buildings with 7 to 11 floors, have a higher share coefficient than multi-storey buildings, generally between 10% and 16%. In addition, if a small high-rise building has an elevator, the sharing coefficient may reach about 20%, and the higher the floor where you live, the higher the sharing you need to bear.

3. Villas. If you buy a villa, you don't need to bear the shared area, after all, all the space is your own and only for your own use, such as gardens, garages, entertainment rooms, etc., but the price of the villa is also quite high. As for townhouses, although there is a shared area, it is very small.

As for how to deal with the large shared area, and how much the shared area is appropriate, I will introduce it here, do you understand? If the shared area is very large and exceeds the value set by the regulations, then it is necessary to negotiate with the developer and try to resolve it peacefully, otherwise you can only go through legal procedures to protect your legitimate interests.
