Ok I have seen it I just didn't know what it was.
It would make a great base for a modern tower, similar to Hearst in New York, which I believe was also planned to be a taller building that never came to be.
I don't think it would fit in so well in Winnipeg, but it would look great in Calgary, much better than the Bow. I don't really like it. The same architect can have ups and downs, and Bow is one of Foster's downs.
