Gan is 179m tall from the natural ground. (all the other 187m or 184m are wrong)
Here a view from the natural ground
I don't why you couldn't include it, especially when it is possible to see the tower from this natural ground.
Note that the undrgound parking are bellow and not included in the 179m.
Gan tower is 179m form the natural ground and 166m from the concrete slab.
