How to calculate the floor area of the balcony area?

How to calculate the area of the concave balcony of the building?

Answer: The floor area of a fully enclosed balcony is calculated as 1 2 of the horizontal projection area. 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. 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, and the semi-enclosed balcony of the house that has been sold cannot be changed to a fully enclosed balcony at will.

Ask whether it is 1 2 or all of them"?

Ask what is the area of a horizontal projection.

Answer: Horizontal projected area refers to the projected area of an object on a horizontal plane. Assuming that when the sun is at its peak, the area enclosed by the shadow outer contour of the house falling on the ground is called its horizontal projection area. There is no necessary relationship between the horizontal projection area and the total area of the building.

Regardless of whether the balcony is closed or not, the construction area is calculated according to 1 2; The terrace bai refers to the use of the roof surface without a roof or a balcony with a floor height (roof cover) greater than 5 meters, and the construction area cannot be calculated.

Unenclosed balconies are calculated based on the horizontal projection area of the balcony covered within 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.

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.

1. Meet the standards of copying.

For the non-enclosed balcony of the dwelling, the building area is calculated according to the half of the horizontal projection of the enclosure. If it is exceeded, the DAO excess part is calculated as the entire construction area. Enclosed balconies are counted for the total floor area regardless of whether they meet the following criteria.

1) The construction area 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.

2. If the depth of the inner balcony and composite balcony (the distance from the outer edge of the main structure to the vertical extension of the interior) is not more than meters, half of the construction area shall be calculated. If it exceeds the meter, the excess part shall be calculated as the entire construction area.

3. When the depth of the unenclosed balcony (the vertical distance from the outermost edge of the balcony to the outer edge of the main structure) is not greater than meters, the construction area is not calculated; When it is larger, half of the floor area is calculated.

4. In addition, the following balconies are regarded as closed balconies, and the total construction area is calculated:

1) The width of the open surface of the balcony is less than 1 3 of the width of the room of the balcony.

2) Set up an enclosure wall with a height greater than a meter below the open surface of the balcony.

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.

In the calculation of the BAI building surface.

When the enclosed balcony is full, the whole part of the projection area is included in the construction area of the DAO suite; and the non-enclosed version of the balcony, then according to.

Half of the projection area of the right is included in the building area of the suite.

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, and the semi-enclosed balcony of the house that has been sold cannot be changed to a fully enclosed balcony at will.

The whole inside the building structure is counted, and the outside of the structure is counted 1 2 (the enclosed balcony is calculated as the whole area, and the non-enclosed balcony is calculated as half of the area).

Balconies don't count as area.

Bai is not divided according to X-line cities, and there is no such rule at all. DAO "Calculation of the Built-in Area of the Construction Project.

Clause 3 0 18 of GB T50353-2005: The balconies of the building shall be calculated according to 1 2 of its horizontal projection area. In other words, regardless of whether the balcony is closed or not, it is half counted.

According to what you said, the meter should be the size of the balcony outside, and it is a cantilever board. If the developer says it doesn't count the area, then you're getting a good deal.
