How to calculate the balcony area and what are the rules for calculating the balcony area

The balcony can be counted as the purchase area, some of the balcony area is all included in the construction area of the house, some are half of the balcony area included in the construction area, and some are not included in the construction area. According to the regulations, only the balcony with a cover and a maintenance structure (railing) on this floor is calculated as an area, which is specifically divided into the following two situations: 1. The balcony is a closed so-called closed balcony, which refers to a balcony equipped with glass or plastic steel windows.

However, it must be a closed balcony with planning approval documents or construction drawings approved by the planning department, and the area can be fully included in the construction area. 2. The balcony is an unenclosed unenclosed balcony, which is calculated according to the horizontal projection area of the balcony covered in the maintenance structure. If the horizontal projection of the upper cover is less than half of the area of the balcony floor, then the entire balcony is not counted as an area; If the horizontal projection area of the upper cover is less than the area of the balcony floor but greater than half of it, it is calculated as half of the horizontal projection area of the upper cover.

1.A balcony, also known as a balcony or balcony, is a platform that protrudes from the outer wall of a building and is supported by columns or brackets, and its edges are built with railings to prevent objects and people from falling out of the platform range, which is an extension of the building. Although a balcony and a balcony refer to the same kind of building, there are some slight differences between the two, a platform without a roof and no cover is called a balcony, and a platform with a cover is called a balcony.

Balconies are divided into enclosed balconies and semi-enclosed balconies.

2.When calculating the construction area, the enclosed balcony is included in the construction area of the suite according to the projection area; For non-enclosed balconies, half of the projected area is included in the floor area of the suite.

3.The closure method of the balcony is subject to the approved planning and design drawings of the commercial housing, and the real estate developer cannot change the closure method without authorization.

To elaborate on you: the area must be calculated if the balcony has a cover and a maintenance structure (railing) on this floor. 1. About the enclosed balcony.

The so-called closed balcony is a balcony with glass or plastic steel windows. However, it must be a closed balcony with planning approval documents or construction drawings approved by the planning department to be fully counted. Otherwise, it is only one or two thousand to seal a balcony made of plastic steel, and the extra three or five square meters are worth more than 100,000 yuan in a big city.

2. Unenclosed balconies are calculated as half of the horizontal projection of the upper cover in the maintenance structure. a, if the upper cover spans the floor, for example, the balcony is on the third floor, but its cover extends from the ground on the fifth floor, then the balcony is not counted as an area. b. If the horizontal projection of the upper cover is less than one-half of the floor area of the balcony, then the entire balcony is not counted as an area; If the horizontal projection area of the upper cover is less than the area of the balcony floor but greater than half of it, it shall be calculated according to half of the horizontal projection of the upper cover.

Almost all houses built by developers will be equipped with one or two balconies for the owner, and the size of the balcony area is related to the balcony structure and the area of the house. Let's take a closer look.

1. The calculation rule of balcony area is: the balcony area of the building should be calculated according to half of its horizontal projection area. The details are as follows:

1) If the balcony is a closed balcony, then the balcony area is calculated according to the projection area at the periphery level.

2) If the balcony is a balcony (bottom balcony), then the balcony area is calculated according to half of the projection area at the level of the bottom plate.

3) If the balcony is a balcony with a slag stove, then the balcony area is calculated according to its net area, which is half of the wall area with baffle wall.

4) If the spine digging balcony is a half-raised and half-concave balcony, then the area of the balcony protrusion part is calculated according to half of the projection area of the horizontal bottom plate, and the area of the recessed part of the balcony is calculated according to half of its net area.

2. Different provinces have different requirements for the calculation rules of the balcony area of the house, so the calculation should be carried out according to the local calculation rules of the balcony area of the house. Because many developers and renovation companies will take advantage of the loopholes in the calculation rules of people's calculation rules for the balcony area of the house for personal gain, so that the owner spends extra money to buy the balcony.

3. When signing the contract, the owner should carefully read the calculation rules of the balcony area of the house marked on the contract, if the contract is not marked, or the calculation rules of the balcony area on the contract are very vague, then the developer or the decoration company should draw up a new contract, so as to avoid being deceived.

The above is a detailed introduction to what the calculation rules of balcony area are, I hope it can help you. Most of the balcony area is different, because there are many kinds of balcony area cherry blossom core and balcony structure, so when calculating the balcony area, it should be calculated according to the relevant calculation rules.

Balconies are half the size.

On May 10, 2018, the Zhejiang Provincial Department of Housing and Urban-Rural Development, the Provincial Department of Land, Provincial Surveying and Mapping, the Provincial Civil Air Defense and the Provincial Fire Protection Department jointly formulated and officially issued the Zhejiang Provincial Engineering Construction Standard - "Technical Regulations for the Calculation of Construction Area and Comprehensive Measurement of Construction Completion", which made new provisions on the calculation rules of construction area

For the newly transferred (or allocated) land in Zhejiang after July 1, the balcony in the residential suite shall be calculated according to 1 2 regardless of whether the balcony is closed or not. If the ratio of a single residential balcony to the total area (excluding balconies and bay windows) after 1 2 calculation exceeds 7%, the excess part shall be calculated according to the full area. At the same time, there are also parts of the equipment platform, which can not be included in the construction area.

This new regulation on the area of balconies - whether the balconies in a residential suite are closed or not, the floor area is calculated according to 1 2 of the horizontal projection area of the perimeter of the enclosure or enclosure facilities. To put it simply, it is calculated according to half of the area regardless of whether the balcony is wrapped or not.

Common types of balconies

1. Enclosed balcony and non-enclosed balcony.

An enclosed balcony refers to a balcony that is enclosed both in its original design and after completion; An unenclosed balcony refers to a balcony that is not enclosed after the original design or completion.

After the completion of the enclosed balcony or unenclosed balcony, the owner or developer shall not change the type of balcony closure at will.

2. Bottom balcony and pick balcony.

The bottom balcony refers to the balcony on the first floor of the house; Balcony refers to the balcony above the second floor (including the second floor) of the house.

3. Concave balcony and convex balcony.

The concave balcony refers to the balcony that is recessed into the outer wall (column) of the floor; Convex balcony refers to the balcony that protrudes from the outer wall (column) of the floor.

Compared with convex balconies, concave balconies are more solid and reliable in terms of the building itself and people's feelings, and the safety factor may be larger.

In high-rise buildings, considering safety factors, concave balconies are generally the majority; In multi-storey buildings, convex balconies are more common.

It should be noted that the balcony is also part of the main structure of the building, and the structure cannot be changed at will or closed by itself.

4. Composite balcony.

The composite balcony combines the characteristics of the concave balcony and the convex balcony.

5. Double-height balcony.

That is, two floors to make a balcony, the balcony has a height of two floors. The double height allows for a wider view and better lighting.

As shown in the red box in the figure below, there are balconies on odd-numbered floors and no balconies on even-numbered floors, and this convex balcony has a height of 2 floors. There are also concave balconies, convex balconies and composite balconies in double-height balconies.

How to calculate the balcony area

1. The balcony in the main structure is calculated according to the horizontal area of the outer periphery of the structure.

2. The balcony outside the main structure is calculated according to the horizontal projection area of the structural bottom plate1 2 area.

3. As long as the balcony is in the main structure, whether it is closed or open, it will be included in the area.

According to the Code for Calculation of the Floor Area of Construction Projects, the following items should not be calculated in area: 1 Building passage (ground floor of arcade and street building). 2 Equipment pipe mezzanine in the building.

3. Single-storey rooms separated from the building, hanging curtains on the stage and backstage, overpasses for scenery, terraces, etc. 4 Rooftop cisterns, trellises, pergolas, terraces, outdoor swimming pools. 5. The platform of the operating platform, the feeding platform, the installation box and the tank in the building.

6. Legs, wall columns, buttresses, steps, wall plastering, decorative surfaces, inlaid block surface layers, decorative curtain walls, shelves (boxes) for air conditioners, bay windows, components, accessories, awnings with a width of up to and below, and decorative balconies and verandahs that are not connected to the building. 7. Overhead corridors without permanent roofs, outdoor stairs, and outdoor steel stairs and ladders for maintenance, fire protection, etc. 8 Escalators, moving walks 9 Independent chimneys, flues, trenches, oil (water) tanks, gas cabinets, water towers, oil (water) tanks, silos, trestles, underground civil air defense passages, subway tunnels.

Therefore, the terrace cannot be counted as a floor area. ]

The state stipulates that the construction area of closed balconies and corridors shall be calculated according to their horizontal projection area. Concave balconies, balconies are calculated as half of their horizontal projection area. ]

According to the provisions of the "Real Estate Surveying Code", the construction area of a fully enclosed balcony is calculated according to its peripheral horizontal projection area; The floor area of an unenclosed balcony is calculated at half of the horizontal projection area of its periphery. The closure method of the balcony shall be subject to the approved "Commercial Housing Planning and Design Drawing", and the developer shall not change it without authorization. When some sellers sell houses, the balcony is not closed, but when the building is handed over, the balcony is closed and the buyer is charged the other half of the fee, which is an act in violation of the "Commodity Housing Planning and Design Drawing" submitted for approval, and the buyer may not accept it.

According to the "Residential Design Code", each dwelling should be provided with a balcony or terrace. Balconies and rain covers should be drained in an organized manner; The rain cover should be waterproof, and the balcony should be waterproof.

For unenclosed balconies that meet the criteria below, the floor area should be calculated at half of the horizontal projection of the envelope. If it is exceeded, then the excess part is calculated as the total floor area. Regardless of whether the enclosed balcony meets the following criteria, the floor area must be calculated.

1. For units with a construction area of 90 square meters and below, the total projection area of various balconies shall not exceed 12 square meters.

2. The construction area is 90 square meters to 140 square meters, and the total horizontal projection area of each balcony is not more than 15 square meters.

3. Residential units with a construction area of more than 140 square meters, and the total horizontal projection area of each balcony shall not exceed 18 square meters.

4. The balcony area of low-rent housing and affordable housing can be calculated according to the standard of 90 square meters of construction area. If the state has other provisions, it is a different matter.

5. If the depth of the inner balcony and composite balcony does not exceed 1.5 meters, only half of the construction area needs to be calculated. If it exceeds 1.5, the excess part shall be calculated as the total construction area.

6. When the depth of the unenclosed balcony does not exceed 0.6 meters, the construction area is not calculated; When it exceeds 0.6 meters, half of the floor area is calculated.

7. The following balconies are regarded as closed balconies, and the total construction area is calculated: a. The open width of the balcony is less than one-third of the width of the room. b. Set up a retaining wall with a height of more than 1.5 meters below the open surface of the balcony.

For unenclosed balconies of dwellings that meet the following criteria, the floor area is calculated at half of the horizontal projection of the envelope. If exceeded, the excess part is calculated as the entire floor area. Enclosed balconies are calculated for the entire floor area.

1. The construction area (refers to the peripheral horizontal projection area of each floor above the foot of the external wall (column) of the house) is 90 square meters and below, and the total horizontal projection area of various balconies (calculated by the balcony floor) is not more than 12 square meters.

2. The construction area is 90 square meters and 140 square meters, and the total horizontal projection area of various balconies does not exceed 15 square meters.

3. Residential units with a construction area of more than 140 square meters, and the total horizontal projection area of various balconies shall not exceed 18 square meters.

4. The balcony area of affordable housing and low-rent housing can refer to the house type standard with a construction area of less than 90 square meters. When the state provides otherwise, follow those provisions.

According to the current Bai line construction area calculation specification: balcony.

Du whether it is zhi or not

Closed buildings are calculated according to 1 2 construction area DAO; The exposed terrace refers to the use of a balcony with no roof or a floor height (roof) greater than 5 meters, and the construction area cannot be calculated. In addition, there are some special regulations in the local industry authorities of various provinces, municipalities and prefectures, please check online or relevant departments, or find a local qualified housing surveying and mapping company for consultation.

How to calculate the floor area of the balcony, whether the floor area of the first floor includes the balcony, canopy, eaves, and how to calculate the sub-division?

How about the balcony. Calculation of floor area?

Answer: The balconies of the building are calculated according to 1 2 of its horizontal projection area, (the relevant regulations for the sale of houses are: fully enclosed balconies are calculated according to the full area, and unenclosed balconies are calculated according to 1 2 of their horizontal projection area).

How to calculate whether the floor area of the first floor includes a balcony?

Answer: First of all, let's unify it, and if we change the "first layer" to "the bottom layer", it will be easier to answer; There is no balcony. But it is customary to call it "one floor" above the bicycle garage on the ground floor, and the "first floor" includes the balcony.

How to calculate whether the floor area of the first floor includes a canopy?

Answer: Let's talk about the calculation first: the width from the outer edge line of the canopy structure to the outer edge line of the outer wall exceeds 1 2 calculated according to the horizontal projection area of the canopy structural panel.

Something of this magnitude is rarely found in a dwelling, and if it does, it is not reasonable to count it on the "ground floor" of the first floor, and it should be apportioned like a staircase (unless it is used separately). If it is not a residence, it does not need to be shared.

How to calculate whether the floor area of the first floor includes overhangs?

Answer: In the provisions on the calculation of the floor area, there is no provision on the calculation of the floor area of the eaves.
