Excerpted from the "Code for Calculation of Construction Area of Construction Projects" is a national standard, numbered GB T50353-2013, which has been implemented since July 1, 2014.

The national standard "Code for Calculation of Construction Area of Construction Projects" (GB T50353-2005) stipulates that the balcony of the building shall be calculated according to 1 2 of its horizontal projection area. But now, in order to prevent developers from stealing the area, there are different regulations on the size and depth of balconies, but there is no distinction between closed and non-enclosed balconies.
Sealed balconies and unsealed balconies are not the same when calculating the area, the balcony part of the sealed balcony is counted as the full area, and the unsealed balcony is only half of the area! I believe that everyone will calculate this account.
