I knew the inclusion of the Nova Centre in that list would be controversial.
I was just talking about the budget spent on the finishes. Curtain wall, real stone, special touches like, in the case of Nova Centre, the curved glass. These are within the ballpark of what you might see on a downtown project in Toronto or Vancouver. It also has large commercial spaces that have attracted major chain tenants, something people might or might not like but which I associate with "major" projects and was rare in Halifax 10-15 years ago. I'm not sure how I feel about it. I don't think you'd want a city to be only complexes like that but sometimes they can add to the mix.
Aside from that I get the impression Queen's Marque also has a bit of a local feel whereas the glass boxes feel more generic. Queen's Marque is a style of building that I could imagine being built in Halifax but not a bunch of other cities. The waterfront site helps to make it more distinctive. I associate simplicity and solidity with Halifax (old and new buildings) whereas around here a lot of the new stuff is quite airy looking. This goes way back. Halifax has a very "Georgian" character that was more classically inspired and started to go out of style in the late 1800's as ornate Victoriana became more popular.
