I think you will find that the people living around the heliport already do complain.
Presumably, if they put the new heliport on the top of these new buildings, that will end the use of this facility by singe engine helicopters and anything else not operating Class 1?
Don't be entirely surprised either if the pad gets removed from the plans at some stage, leaving just a hotel and apartments .............
And there is b***er all we can do about it!
