Can the awning be calculated? How is the construction area regulated?

The awning can be used to calculate the building area. The specification stipulates that the building area should be calculated when the awning is wider than 2.1m.

According to the "Code for Calculation of Building Area of ??Construction Projects" when calculating the building area of ??the first floor, when the width of the awning is greater than 2.1m, it should be calculated into the building area of ??the first floor. The awning of a building is generally an overhanging cantilever (or column) structure on the upper part of the outer door. The most common one is the outer door awning on the first floor. When the awning is wider than 2.1m, it should be counted as a building on the first floor. area inside. If the awning is on the second floor or above, and the width of the awning is greater than 2.1m, it should be calculated in the corresponding floor.

The awning refers to a separate building component above the entrance and exit of the building, protruding from the wall, and used to block rainwater. Awnings are divided into column-based awnings (including independent column awnings, multi-column awnings, column-wall hybrid support awnings, and wall-supported awnings) and column-free awnings (cantilever awnings). The width of the overhang refers to the width from the outer edge of the awning structure to the outer edge of the exterior wall structure. If it is arc-shaped or special-shaped, the maximum width shall be taken.

Regulations on calculating building area

1. The building area should be calculated based on the sum of the peripheral horizontal areas of the natural layer exterior wall structure. If the structural floor height is 2.20m and above, the full area should be calculated; if the structural floor height is below 2.20m, 1/2 area should be calculated.

2. When there are partial floors in the building, for the second floor and above of the partial floors, those with enclosure structures shall be calculated based on the peripheral horizontal area of ??the enclosure structure, and those without enclosure structures shall be calculated according to the outer horizontal area of ??the enclosure structure. Calculated based on the horizontal area of ??the structural floor, and if the structural floor height is 2.20m or above, the full area should be calculated, and if the structural floor height is below 2.20m, 1/2 area should be calculated.

3. For the sloping roof forming the building space, the total area of ??the parts with a clear structural height of 2.10m and above should be calculated; the parts with a clear structural height of 1.20m and above and below 2.10m should be calculated as 1/ 2 Area; the building area shall not be calculated for parts with a clear structural height below 1.20m.
