Here's a map of Aura's currently approved building height:
As you can see, the top main roof slab sits at 231.09m and they wish to increase this by 12m (thus increasing the top parapet by 12m as well).
Once again, I'm left scratching my head as to how Aura's total building height can go from 243m originally, then to 252m in Dec09, and now 264m today, without adding a single floor...
Tacking on 21 extra meters (to the original plan) is no small potatoes.
Not that I'm complaining, higher the better!
