Don't like the concept at all. Very few buildings, let alone towers, have plaza space in Halifax. They should invest in an observation deck.
It would be nice to see Simons though. Maybe in a historic building like the one below where Doull's book store was...3 or 4 floors. Similar to Montreal.
Better location for Simons:
