I was reading the earlier comments in this thread, but can't find the exact ones to quote now... regarding this 30 storey tower sticking out by itself, I don't think it's exactly something to worry about. I can't see something like this going up and there not being some sort of push to full in the area in between with more buildings between 6-40 storeys.
If this development is proven successful, there's good reason to believe other developments of similar, or even slightly scope, could be successful too.
Before, the rest of that infill happens though, I don't think there's much to worry about a single 30 storey tower looking odd by itself.
The Lakhta Centre in St. Petersburg is a good example of how a single tower can actually look quite nice without other similarly tall towers nearby.
Though, I don't think Moncton will have this problem/situation, especially not if Mark Carney and the NB Liberals actually live up to their "big build, big bold" ideals and sloganeering when it comes to responding to the "housing crisis". I think Moncton has a golden opportunity to be the "Mini-Mississauga of the East", and by that, I mean there's a good opportunity to build a nice little "second downtown" of mostly residential high rises (between 10-40 storeys).
But instead of being a car-centric, urban hellscape (like Missisauga's residential high rise cluster is), Moncton's high rise residential cluster could be one that promotes walkability, active transportation, and entrepreneurial opportunity. Which would would make it a lot more like the mini Toronto of the East and a lot less like Missisauga.
I think it's kind of funny how some people wouldn't want Moncton to be known as the Toronto of the East lol, there's much, much worse cities to be compared to, unless we are talking about their hockey teams.
