Excuse me, how to calculate the pool area of stairwell?

The pool area is calculated according to the building construction area. /kloc-Houses below 0/2 floors:

Building area-building area/1.33 is the pool area.

/kloc-Tower with elevator above 0/2 floor:

Building area-building area/1.44 is the pool area.

Not half what you think. .....

Of course, the design unit is different. Moreover, some units with the same construction area differ by 5 or 6 square meters. These are normal phenomena!

I really don't know this. Ask the developers and see how they explain this problem. Generally we calculate the pool area according to my method. I really can't explain your situation ... I'm really sorry.
