1. Does the balcony count as the construction area?
Terrace refers to the roof for residents to engage in outdoor activities, or extended from the bottom of the building, and has a building envelope. If there is no roof or the horizontal projection area of the roof is less than the horizontal projection area of the building envelope 1/2, the building area will not be calculated. So the balcony is not counted as the building area.
Second, how to calculate the construction area?
(1) Construction area of single-storey building: This area is calculated according to the horizontal area of the periphery of the structure above the toe of the external wall, and shall meet the following requirements:
1) If the height of a single-storey building is 2.20m or above, the total area shall be calculated; If the height is less than 2.20m, the area shall be calculated as 1/2.
2) When the internal space of sloping roof is used, the total area of the part with clear height exceeding 2. 10m shall be calculated; The area of 1.20 ~ 2. 10m shall be calculated; The part with clear height less than1.20m is not counted as the area.
The calculation of single-storey building area should be determined according to different heights. Its height refers to the vertical distance between the indoor ground elevation and the roof panel structure elevation. If a flat-topped single-story building has a sloping roof panel, the height refers to the vertical distance between the indoor ground elevation and the lowest structural elevation of the roof panel.
Clear height refers to the vertical distance between the ground or the ground and the lower surface of the upper floor or the bottom surface of the ceiling.
(2) Building area with local floors in a single-storey building: for the second floor and above of local floors, the horizontal area of the periphery of the maintenance structure should be calculated; if there is no envelope, the horizontal area of the structural floor should be calculated. The total area should be calculated if the height is 2.20m or more; If the height is less than 2.20m, the area of 1/2 should be calculated.
(3) Building area of multi-storey building: the first floor of multi-storey building should be calculated according to the horizontal area of the periphery of the institution above the toe of the external wall; The second floor and above shall be calculated according to the horizontal area of the external wall structure. The total area should be calculated if the height is 2.20m or more; If the height is less than 2.20m, the area of 1/2 should be calculated.
The construction area of multi-storey buildings should be calculated according to different floors. Height refers to the vertical distance between the elevation of upper and lower floors. The lowest floor of a building, with a foundation slab, refers to the vertical distance between the structural elevation of the upper surface of the foundation slab and the structural elevation of the upper floor; When there is no foundation slab, it refers to the vertical distance between the elevations of the superstructure above the ground elevation. The height of the top floor refers to the vertical distance between the floor structural elevation and the roof structural elevation. For a roof with roof slope, the height refers to the vertical distance between the floor structural elevation and the lowest roof structural elevation.
(4) Building area of sloping roofs of multi-storey buildings and spectators' stands of venues: when designed and used, the area of the part with clear height exceeding 2. 10 shall be calculated as 1/2; When the design is not adopted or the indoor clear height is less than 1.20m, the area shall not be calculated.
The space in the sloping roof of a multi-storey building and the grandstand of the stadium should be regarded as the space in the sloping roof, designed and utilized, and its area should be determined according to its clear height. The design does not use space, and the building area should not be calculated.
(5) Construction area of other buildings: basement and semi-basement (workshops, shops, stations, garages, warehouses, etc.). ), including the corresponding entrances and exits with permanent roofs, calculated according to the horizontal area surrounded by the outer contour line of the upper opening of the external wall (excluding the lighting well, the moisture-proof layer of the external wall and its protective wall). The total area should be calculated if the height is 2.20m or more; If the height is less than 2.20m, the area of 1/2 should be calculated.
(6) Construction area of cantilever scaffold overhead floor and deep foundation overhead floor of sloping buildings: if it is designed and used with enclosure structure, the height is 2.20m? The above part should calculate the overall area; The area of12 should be calculated for the part with a height less than 2.20m, and the design and utilization of the overhead floor of the building with hanging feet without retaining structure should be calculated according to the horizontal area of its utilization part12; This design does not use the deep foundation overhead floor, the overhead floor with hanging feet on the slope, and the space in the sloping roof of multi-storey buildings and the space under the stands of venues should not be calculated.
From the above, we can know that balconies are generally included in the construction area, and the specific calculation method of balcony area is different according to the standard parameters and regulations given by specific real estate developers. To analyze the actual parameters, we can further know that the calculation and measurement methods of building area are also very important, especially when we doubt whether the data given by real estate developers are correct, we can refer to the above and measure ourselves.
