Question 2: How to calculate the housing area is generally based on the area of the real estate license.
The carpet area of your own house (that is, the place where carpets and floor tiles can be pasted), plus the area occupied by building components such as columns and walls, plus the public * * * area shared by each household such as corridors, elevators and equipment floors, is the construction area. Moreover, according to different huxing, the calculation of balcony area is different, and some houses have only half the area. And the usable area is almost the carpet area (that is, the area where you can generate energy yourself).
The building area on the property certificate may be slightly different from that on the purchase contract, but it will not be too big, which is normal. When you get the real estate license, you can look at the page with surveying and mapping results. There is a pool coefficient, common banlou 1.33 and tall tower 1.44. This pool coefficient is the ratio of the building area and the usable area (note that this usable area is not the usable area of the suite mentioned in your question, but the carpet area plus the area occupied by the building components) that falls on the real estate license.
Question 3: How to calculate the building area of the house? 1. The building area is the horizontal projection area of the building periphery. Simply put, it is length x width, and both length and width are the dimensions of the house;
2. If it is an irregular-shaped apartment, such as an arc balcony, stairwell, elevator room, etc. You can divide it into rectangles one by one and then calculate the area;
3. Crucially, if there are two or more households in a staircase, the wall part used by * * * must be shared by one person, or more than one * * * can share the wall area. For example, there are two households in a staircase, and the partition wall is 24CM thick, so when calculating the area, everyone should share 12CM. Then there is the pool area, which is stairwells, elevators, public corridors and so on. To put it simply, if there are two households in one staircase, the building area is 200 square meters, and the apartment type is exactly the same, then the building area of your house is 100 square meters, including the pool area.
Question 4: How to measure and calculate the area of the house? Area is length times width. Generally, houses are calculated according to the construction area. And the construction area includes the interior area and the pool area, and the interior area is mathematically the length multiplied by the width.
The so-called pool refers to the lobby, public hall, corridor, aisle, elevator (building) hall, stairwell, elevator shaft, elevator machine room, garbage chute, pipe shaft, water pump room, fire escape, power supply and distribution room, guard room on duty, etc. , as well as public houses and property management houses serving the whole building, as well as other functions of the building.
The area calculation method of the house is as follows:
1, the total square meters obtained by multiplying the length of the bedroom by the width.
2. The total square meters obtained by multiplying the length and width of the living room.
3. The total square meters obtained by multiplying the length of the toilet by the width.
4. The total square meters obtained by multiplying the length of the kitchen by the width.
5. Add up all the figures.
6. Measure the total area of the corridor, and divide this number by the number of floors to get the public area.
7. The total housing area minus the public area is the housing area.
Question 5: Knowing the building area, how to calculate the indoor square? Knowing only the building area, it is impossible to calculate the accurate indoor area, because you don't know how the walls are distributed and how many there are.
Calculation method of indoor space: length * width * height = room space.
Calculation method of indoor area: length * width = room area.
Example:
The house is 12m long, 4m wide and 3m high.
Room space: 12*4*3= 144 cubic meters.
Room area: 12*4=48 square meters.
After the renovation of the new house, there is indoor air pollution, including formaldehyde and other gases harmful to the human body. It is recommended to open the window for 2-4 weeks, and put some flowers indoors, such as chlorophytum, Cynanchum multiflorum, ivy, aloe, agave, hibiscus, chrysanthemum, radish, begonia, Commelina, etc. Chlorophytum can absorb more than 80% of indoor harmful gases, and its ability to absorb formaldehyde is super strong.
Question 6: How to calculate the square meter of a house?
Housing construction area refers to the calculation of peripheral horizontal area and horizontal projection area, including the calculation of construction area, existing construction area and usable area.
General provisions of calculation rules for construction area
1. The construction area is calculated according to the horizontal projection area of each floor above the external wall (column) of the building, including balcony, corridor, basement, outdoor stairs, etc. , and it is a permanent building with solid structure and a height of more than 2.20m (including 2.20m, the same below).
2. The * * * construction area of the house refers to the construction area jointly occupied or used by all property owners.
3. The usable area of the house refers to the total usable area of the house, calculated according to the horizontal area of the interior wall of the house.
4. The number of floors of a house refers to the natural number of floors of the house, which is generally calculated by the indoor floors above 0.00 mm. False floors, attached floors (mezzanine), inserted floors, attics (hidden buildings), decorative towers, stairwells and water tanks protruding from the roof are not counted.
5. The floor of a building refers to the floor of the building. The groundwater level is represented by a negative number.
6. The area occupied by building structures (such as walls and columns), including the area occupied by basements, but excluding the area occupied by patios, balconies outside walls and objectively existing stairs.
The scope of calculating the total construction area
1. The construction area of single-storey houses with permanent structures is calculated as one floor. If it is a single-storey house with several floors, if it meets the general requirements of the code, the construction area should also be calculated.
2. Multi-storey and high-rise buildings are calculated according to the total construction area of each floor.
3. If the technical layer (pipeline layer, adhesion layer, interlayer, etc.). ) When the height of the building exceeds 2.20m, it shall be calculated according to the horizontal area of the surrounding walls.
4. Through the passage of the house, the foyer and foyer in the house are calculated as one floor. In the hall corridor, if the floor height exceeds 2.20m, the construction area shall be calculated according to its horizontal projection area.
5. The construction area of stairs, stairwells, elevator (sightseeing elevator) wells, lifting wells, garbage lanes and pipeline wells is calculated according to the natural floor of the house.
6. Outdoor stairs with permanent structure and roof are calculated according to the horizontal projection area of the periphery of each floor.
7. The roof of the house is a permanent building, and the stairwell, water tank room and elevator machine room with a height of more than 2.20m are calculated according to the peripheral horizontal area.
8. The original design of the use space under the sloping roof, the height of which exceeds 2.20m, shall be calculated according to the horizontal projection area of its periphery.

2. porches with independent columns, single-row columns, sunshade, carport and freight shed ... >>
Question 7: How to calculate the area when buying a house? In the disputes over the sale of commercial housing, the area problem accounts for the largest proportion. Some unruly real estate developers take advantage of the weakness that buyers can't re-examine the construction area of the whole building and make a big fuss about the area. On the one hand, they let buyers pay 3% of the purchase price, on the other hand, they let buyers get 3 sets of interior construction area less. The practice of real estate developers not only allows buyers to pay for the increased pool area, but also pays various fees such as property service fees and heating fees for them for many years. It can be said that this inexplicable cost will accompany the buyers for life.
If property buyers want to avoid losing money in area, they must work hard on Articles 3, 4 and 5 of the agreed contract.
The concept of area should be clarified.
With the qualification of real estate surveying and mapping units, surveying and mapping results approved by the real estate administrative department for examination and approval of the construction area for property registration area. Buyers who purchase pre-sold commercial housing should generally cross out the option of [property registration] in Article 3 of the contract, keep the option of [contractual agreement], and must clearly stipulate the construction area and interior construction area in Article 3 of the contract at the same time. If possible, they can try to agree on an additional internal usable area for their own measurement, and make clear whether the balcony is [closed] or [not closed].
The construction area of commercial housing consists of interior construction area and apportioned construction area, and interior construction area consists of interior use area, interior wall area and balcony area. People often say that the utilization rate is the ratio of the usable area to the building area. Generally speaking, the utilization rate of reasonably designed buildings is about 72-75 for high-rise tower houses, 78-80 for high-rise board houses and 85 for multi-storey houses. Before buying a house, buyers can judge whether the design and price of the house are reasonable by calculating the utilization rate of the house they buy.
The buyer should pay attention to the following issues when agreeing on the interior construction area:
1. The interior construction area includes the interior wall area. Although only half of the thickness of the external wall is included in the indoor construction area, for a house with brick-concrete structure, the bottom wall is thick and the upper wall is thin, so the indoor use area of the same unit upstairs and downstairs is still different. On the same floor, even if the indoor building area is the same, the use area of corner units will be smaller than that of the units sandwiched in the middle.
2. Even the usable area in the suite is not the carpet area, because the pipe well in the room should be included in the usable area in the suite. Therefore, when buying a house, it is best to let the real estate trademark know how big the area of the pipeline well is. Because outdoor meter checking is now advocated, heating will be measured by households. In the past, the vertical pipes of many old houses became horizontal pipes of new houses. When buying a house, buyers should pay attention to whether only the standpipe of the house you bought is placed in the pipeline well, and do not count the public standpipe well into their own interior construction area.
3. The interior construction area also includes the balcony construction area. Property buyers should make it clear that the area of closed balcony is calculated according to its peripheral horizontal projection area; The area of non-enclosed balcony is calculated according to half of its peripheral horizontal projection area. Property buyers should also know that the balcony closure method is based on the approved commercial housing planning and design drawings, and real estate developers cannot change its closure method without authorization. The semi-closed balcony of the house that has been sold cannot be changed into a fully closed balcony.
4. According to the regulations, some areas can be calculated, and some areas cannot be calculated. In order to avoid unnecessary disputes, it is best for buyers to ask real estate developers about all the "incomplete" (below the height) areas included in the construction area. For example, how much is the fashionable "bay window" to calculate the indoor construction area? Does the split air-conditioning seat built in the house count as the interior construction area? There are also rooms with stairs and attic. How to calculate the interior construction area of those areas?
When pricing according to the interior construction area, the pool area should not be ignored.
Because Article 34 of the Administrative Measures for the Transfer of Urban Real Estate in Beijing has made a mandatory requirement that "the pre-sale of commercial housing should be priced according to the interior construction area", when signing the pre-sale contract for purchasing commercial housing, buyers and real estate developers can only choose to fill in "1". Calculated according to the "interior construction area" in the newly revised contract model.
Here, I would like to remind property buyers that pricing according to the interior construction area is a way to increase the transparency of the area and calculate the unit price. Pricing according to the interior construction area does not mean that property buyers will not buy the pool area. Buyers should never ignore the agreement on the construction area. The apportioned self-owned building area included in the building area reflects the property rights of the buyers. The buyer shall ask the real estate developer to put Annex II in accordance with Article 35 of the Measures for the Administration of Urban Real Estate Transfer in Beijing;
Question 8: How to calculate the room area? Just multiply the length by the width. That is, 6.5X3= 19.5 square meters, which has little to do with height. However, the height of your room is unusual. Generally, the height of a residential building is about 2.9M, and that of a commercial building is 3.7M Then your height is 4M, so the room space is too open to be equipped with air conditioning like an ordinary room of19.5m2.. Be sure to explain the situation to the sales staff when buying air conditioners.
Question 9: How to calculate the area of the house? How to calculate the square formula As long as you lay a stone, the rural house can be counted as the construction area. If you have a garden club, it is the total area outside your house (including the walls). The balcony is only half the area. The green area is recommended by customers. The more green, the fewer houses, and the greater the publicity ~
