Enclosed balconies are calculated according to what is the floor area

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

The Rules for the Calculation of Floor Area (GBT50353-2005) stipulates:

3 0 18 The balconies of buildings, whether they are concave balconies, raised balconies, closed balconies, or unenclosed balconies, are calculated according to half of their horizontal projection area.

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.

Theoretically, an enclosed balcony is a flat balcony, that is, there is no protruding part, and the overall structure is a plane. The balcony is a balcony structure formed by the connection of the load-bearing and the main steel bar through the independent floor slab of the balcony in the building, which is built in the middle of two floor buildings.

Enclosed balconies are roughly divided into two types of encapsulation:

One is the anti-theft net sealing method, this method can only achieve the effect of security and anti-theft, and other functions can not be played, and can be used in the case of living conditions and relaxation;

The other is in the form of windows, which is the most common.

Calculation standard for the area of enclosed balconies.

According to the relevant laws of China, the calculation method of balcony area is different according to whether it is closed or not. The national standard "Code for the Calculation of the Construction Area of Construction Projects" implemented on July 1, 2005 clearly states that the enclosed balcony shall be calculated according to 1 2 of its horizontal projection area.

In other words, the price of a fully enclosed balcony is equal to the unit price of the property multiplied by the actual measured area of the balcony. For example, if a house has a room size of 100 square meters and a balcony area of 10 square meters, the sales area on the design plan should be marked as 105 square meters instead of 110 square meters.
