Those black grid elements look to me to be attached to the outside edge of the balconies. The “interesting” thing about these two buildings is that they are attempting to present separate designs from any angle you view them from. From Gore park at John st the left building is horizontal white or clear glass balconies and the right is black grid facade. It’s the same if you’re viewing from KW and Hughson. You can never see the same facade from any viewpoint.
Excited for street level brick!
