Excuse me, the floor area of the overhead floor.

If the overhead layer is designed and utilized, and there is an envelope structure at the same time, it is included in the construction area.

Whether the overhead layer is counted as the construction area needs to be determined according to the actual situation: the design and utilization of the overhead layer, and the enclosure structure at the same time, is included in the construction area. If the overhead layer is designed and utilized, but there is no enclosure structure, half of the area shall be included in the construction area.

The overhead layer is designed but not utilized, and it is not included in the construction area.

The building space formed by the deep foundation of the building or the overhead part of the sloping building is not backfilled with earth and stone. Overhead floor is a building term, that is, the layer in the building that is overheaded by columns. The overhead layer is not the latest thing, and it has long appeared in China, such as the stilted building built by the water in the south of the Yangtze River, the bamboo building of the Dai family, the stilted building of the Miao family, and the water pavilion of the Suzhou garden.

Located in Shanxi, the hanging temple built 1,400 years ago contains an overhead layer.

Use the deep foundation to make the overhead layer to be used, and the floor height is more than one meter, and the construction area is calculated according to half of the horizontal area of the periphery of the overhead layer.

If the sloping building uses the stilt as an overhead layer and the floor height exceeds one meter, the construction area shall be calculated according to the horizontal area of the periphery of the enclosure structure.

The mezzanine exceeding meters should be calculated as the floor area, and the floor area ratio should also be included. You have to ask the developer if you want to share it, or he will indicate in the sales contract whether it is a gift or not.

The overhead layer is like a "stilted building", which is a special structure in the southern area, mainly to isolate the dampness of the ground, and the general clearance height is not more than meters. Because when the headroom is greater than the meter, it is necessary to calculate the construction area.

Calculate the floor area.

About the range of converted floor area (calculation of 50%).

It stipulates the part of the building space that is designed to be used but the floor height or net height cannot meet the normal activities of people, or can not fully play the role of sheltering from wind and rain, and there is no envelope structure although there is a permanent roof.

With the progress of science and technology, the development of building materials, in addition to some antique buildings also use the above materials, steel structure and reinforced concrete monopolize all the overhead layers of modern buildings. The advantages of the overhead layer in the form of the building structure are obvious, and the overhead layer is a contribution to human life and residence, such as safety, moisture insulation, ventilation, adaptation to local conditions, and the embodiment of specific artistic customs.

Overhead floors are not counted as areas.

Specific details:

The area is the floor area ratio, and the overhead layer is not counted as the floor area ratio, which refers to the ratio of the total construction area of a community to the land area. For developers, the plot ratio determines the proportion of land cost in the house, while for residents, the plot ratio is directly related to the comfort of living. The same is true for the greening rate.

The higher the greening rate, the lower the plot ratio, the lower the building density, the less area the developer can use for the first time, and the more comfortable the residents. These two ratios determine whether the project is designed from the perspective of people's housing needs or purely from the perspective of making money. For a good residential community, the floor area ratio of high-rise residential buildings should not exceed 5, multi-storey residential buildings should not exceed 3, and the greening rate should not be less than 30%.

However, due to the cost of land, not all projects can be done.

To calculate the area, at least 1 2 area, it may be counted as 100%.

This is just a compromise method to balance the efficiency of land use, increase the activity space, increase the greening rate, the common method of high-density housing in the mainland, anyway, the public is shared to the household, the developer will not lose, and the residents still have a little place to move. (No, you can't use it, and the same sloping housing support as the pillar structure of the pier doesn't count, and it's really useless.) ）

Answer: Kiss, hello, is inquiring about related matters for you, please wait a moment [heart] dear, hello [smile] The method of calculating the construction area of the overhead layer is as follows3, where the design is not used, the construction area should not be calculated.

Smile] [smile].

The floor area should be calculated according to the horizontal projection of its roof, and the structural floor height is 2If it is 20m or more, the full area should be calculated; The height of the structure is 2Below 20m, 1 2 area should be calculated.

1. All the floor heights in the overhead layer and above shall be calculated according to the full area; If the floor height is insufficient, it shall be calculated according to the area of 1 2; 2. If there is no enclosure structure, then 1 2 is calculated.

The original specification 3 0 6 slope of the building pood overhead layer, foundation overhead layer, design to use and have an enclosure structure, the floor height in and above the part should be calculated comprehensive impact; The part where the floor height is insufficient should be calculated 1 2 area. The design to be utilized, no enclosure structure building stilt overhead layer, should be calculated according to the horizontal area of its use part 1 2; The space under the sloping roof of multi-storey buildings and under the grandstand of the stadium should not be calculated as the area of the deep foundation overhead layer, the sloping sloping stilt overhead layer, the sloping roof of the multi-storey building, and the space under the grandstand of the stadium.

New Code 3 0 7: The overhead layer of buildings and the overhead layer of sloping buildings shall be calculated according to the horizontal projection of their roofs. The full area of the structure should be calculated if the floor height is above and above; If the height of the structure is below, the area of 1 2 should be calculated.

Interpretation: The requirement that the "unused" overhead layer in the original specification can be excluded from the area, that is, the area should be calculated regardless of whether it is used or not.

Rules for calculating the construction area of the overhead layer: (according to GB T 50353-2005 Code for Calculating the Construction Area of Construction Projects - Article 1).

1.If the design is used and there is an enclosure structure: the full area should be calculated for the part where the floor height is above and above, and the part where the floor height is insufficient.

1 2 area should be calculated;

2.The overhead layer of the building without enclosure structure that is designed to be utilized: it should be calculated according to 1 2 of the horizontal area of the utilization part;

3.Where the design is not utilized: the construction area should not be calculated.

According to Article 1 of the Rules for Calculating the Floor Area, if your overhead floor height reaches and above, then you need to calculate the full area, otherwise it is 1 2 area.

The first overhead layer is counted as the full construction area above the meter, and the area below the meter is half of the area.

This depends on the specific regulations of each place, and it is usually open to the public.

Nowadays, when building buildings, developers will design overhead floors to bring better results to the whole and bring more convenience to residents, but not everyone knows what kind of existence the overhead floors are. So do you understand whether the overhead layer is considered a construction area, and what are the advantages of the overhead layer? Now let's take a look.

1. Whether the overhead floor is considered as a construction area.

Whether the overhead layer is counted as the construction area needs to be determined according to the actual situation: the design and utilization of the overhead layer, and the enclosure structure at the same time, is included in the construction area. If the overhead layer is designed and utilized, but there is no enclosure structure, half of the area shall be included in the construction area. The overhead layer is designed but not utilized, and it is not included in the construction area.

Second, what are the advantages of the overhead layer.

1. The design of the overhead layer makes the whole community give people an overhead feeling, that is to say, the building is not designed with a residential floor, but the house is designed on the overhead layer, which reduces the isolation protection of the wall.

2. If there is no overhead layer in the community, then parking spaces or box-type transformers will be designed between the stalls, which will greatly reduce the greening and landscape effect and reduce the overall effect. It is different if there is an overhead layer, and the landscape design can bring more comfort.

3. In the overhead layer, public areas such as garages, swimming pools, and clubs can be designed without wasting too much space. In addition, under the overhead layer, various pipelines can also be arranged, which can avoid burying wires under each unit, which increases the difficulty of maintenance in the later stage.

4. When the car is driving in the overhead layer, there is still a large space above the overhead layer for the residents of the community to walk, so there is no fear of traffic problems. And you don't have to hover over the above-ground and underground garages to enter by car.

Regarding whether the overhead layer is considered a construction area, and what are the advantages of the overhead layer, I will first introduce the disadvantages here, do you understand? The overhead layer needs to be counted in the construction area according to the time situation.
