^ Yeah, definitely not far-fetched. I'd imagine that this building would be chasing a mid to upper range demographic, which tells you that they won't be building absolute minimum height levels either.
What's the height on Glasshouse? I couldn't find an actual number. But at 21 storeys, it's probably fair to say that WSII would be a little less than double the height.
Doing some cocktail napkin math, we can say that with 9 ft ceiling heights in Glasshouse + 10'4" on 2-5 and penthouse levels, we're looking at a minimum height of 195.67 feet. I presume a mechanical level/penthouse would push that up at least another 10 feet? Say 205? So taking that average 9.76 feet a floor and multiplying it by 40 gives me 390.4 feet. Less than 30 feet off 201 Portage.
So really, an average ceiling height a bit higher than Glasshouse (or even just an especially tall mechanical level or main floor) would likely push WSII over the top. That wouldn't really take much. An average of 10.6 feet a floor vs. Glasshouse's 9.76 would make WSII the new tallest... that's what, barely 10" per floor difference on average? A combination of a few inches per floor throughout the building, plus maybe an extra foot or two on each of the main, penthouse and mechanical levels,
and you're there. Or perhaps Artis will just jack it up to 42 storeys to satisfy us skyscraper nerds
You STEM guys feel free to shoot holes in my math, it probably wouldn't be too tough to find a mistake in there. But that's where I landed and it looks pretty good!
