I think all three of the above are possible, after all, there are no specifications for various buildings, and the size can be determined by the situation.

It is unreasonable to calculate the construction area of the balcony as well, and the specification stipulates that the construction area of the balcony shall be calculated according to half of the horizontal projection area, and the construction area of the balcony shall not be calculated according to the balcony, whether it is a closed balcony, an unclosed balcony, a concave balcony or a convex balcony.

Balcony is the name of a space in the suite that is divided by function. It can be regarded as an excessive space between indoor and outdoor, except that it cannot be entered, indoor and outdoor are naturally connected. Generally, the balconies of residential buildings are set up in the front eaves or back eaves of the building (two long sides), the protruding exterior wall is called the outer balcony (or called the pick balcony), and the concave exterior wall is called the inner balcony.
