Looking at page 21 of the master plan, it shows the two existing cargo stands at an angle to each other maintaining a nice gap between wing tips as the aircraft are not parked side by side.
On page 23 with Signatures new hangar taking up a good chunk of the old cargo apron both stands are now side by side but further back and so the wing tips are now clear of the side of the cargo building.
It is hard to tell what impact these new stands will have on the parking of an A330 but it looks like both stands will still be the same size.
