Outdoor staircase building area is not considered building area, how to calculate, what basis, said more details
There is no envelope structure, my understanding is the outdoor staircase first, second, three cases,
One layer to the second floor that is 4.8m mark under no envelope structure, in a layer by a permanent roof calculation, included in the construction area of 1/2, the second case in the stairs to be measured, such as building area, While the second floor are not included in the construction area,
When there is a protective structure between the floor and the second floor, there is a need to calculate the full area of the stairs, and in the second case, the stairs are also included in the building area and are not included in the construction area on the second floor,
As for the third case of steel structure awning, I think there is no need to express, see the outdoor steps as long as the expression of the outdoor level can
Count area. Own use included in the rent area. (Varies from place to place). You are 100% money. We use the pool area. You out part of the money.
