That Seattle proposal was a concept by an architect that didn't get selected. For some reason people on SSP saw some images and thought it was a proposal. There's no information about how tall the building might be, though the owner did say something this week about 1.1 msf plus housing, which does suggest a very tall tower. They also said they hired NBBJ as architect.
Nice to see so many cities seem to have new tallests in the works.
Yeah, Calgary is Denver's twin lol!
This building is under construction, core is well over half way up. But it won't be Denver's tallest. Maybe Denver's most interesting skyscraper though.
Hudson Site Tower, Detroit. 734 feet and 52 stories, though, I'm not sure if the floor count is just the tower or includes the podium levels. Site prep works starts in December:
Not sure how much of a "major" city it is, but Grand Rapids does have a metropolitan area of over 1 million people. It's tallest is 10 Ionia, which will be 418 feet and 40 stories.
