How to calculate the floor area of balconies and bay windows

If it is the problem you said, it is in line with the rules of calculation of construction area, you are buying a house, and the calculation of construction area should be calculated in the state of buying a house.

Hello, if the steps to the ceiling of the bay window are less than meters, it is not considered the area, the balcony is divided into inner balcony or outer balcony, outer balcony, half of the area, and the inner balcony is to be counted as the full area. Now you say that the bay window is similar to a balcony and is level with the ground, then it can be understood that the bay window steps are larger than a meter, similar to the inner balcony, and should be counted as the whole area. To put it bluntly, if the balcony made is the outer balcony (one against the wall) is counted as the general area, and the inner balcony is against the wall on three sides, it is considered the full area, thank you, please adopt.

Also, it is best to look at the construction drawings for easy confirmation.

Answer: Calculate the area of buying a house, balcony and bay window. The building space within the main structure is calculated according to the horizontal projection of the periphery of the main structure. Outside the main structure, the depth of the balcony shall not exceed the meter, the outer edge of the bay window shall not exceed the meter of the protruding external wall, and the balcony or bay window that exceeds shall be regarded as the full area of the main house.

1. The bay window is not counted in the construction area, and the construction area of the balcony is defined according to the closure situation.

2. The construction area of the balcony in the suite shall be calculated according to the "Code for Calculation of Construction Area of Construction Engineering" GB T 50353-2005, and the balcony of the building shall be calculated according to its horizontal projection area of 1 2. Specifically:

1) The original design of the enclosed balcony is calculated according to the horizontal projection area of its periphery;

2) The construction area of the balcony (bottom balcony) is calculated according to half of the horizontal projection area of the bottom plate;

3) The construction area of the concave balcony is calculated as half of its net area (including the area of the baffle wall);

4) For the half-lifted and semi-concave balcony, the construction area of the protruding part shall be calculated according to half of the horizontal projection area of the bottom plate, and the construction area shall be calculated according to half of the net area of the recessed part.

Balcony for commercial housing sales: closed safe area counted, non-enclosed half of the area; The bay window does not calculate the area.

According to the latest floor area calculation code, half of the area of the balcony is calculated (whether closed or not), and the area of the bay window is not calculated.

Two cases to count:

1. The building space in the main structure, whether it is called a balcony, a bay window, a terrace, or an entrance garden, is regarded as the main house, and the full area is calculated according to the horizontal projection of the periphery of the main structure.

2. Outside the main structure, the depth of the balcony shall not exceed one meter, and the outer edge of the bay window shall not exceed one meter.

Floor area is a real estate term, which is directly related to the calculation of usable area and utilization rate. Depending on the country and region, the definition and measurement standards may not be consistent. The floor area is generally larger than the usable area.

The construction area is an important technical and economic indicator in the field of construction engineering, and it is also one of the important indicators of national macroeconomic regulation and control. The construction area refers to the horizontal area of the outer structure above the foot of the external wall of the building, and is a physical quantity index that reflects the scale of housing construction in square meters.
