So actually, a 4-6 m difference between corners is totally reasonable; what counts as “ground level” when you’re inside a building like that?
CTBUH defines height usually from the “level of the lowest, significant, open-air, pedestrian entrance”.
So in the context of determining the height, the ground level would be the lower side.
