Actually I don't think that building's THAT bad-looking; I don't know when it was built, but it kind of has a 50s elegance to it. There's a ton of much uglier buildings that I'd take down first.
Now that I look at the rendering again, the diagonals are quite a bit more slender than the supercolumns, so I guess the steelwork in place is in fact permanent.
I saw those as well. I'm no structural engineer, but those look way too small to be the final diagonals. Will they be adding to what's in place already, or are those temporary?
From what I can tell from Riseth's pictures, they're used to provide reinforcement to the blue slab support poles; I guess to keep them from bending under the weight.
<sigh> The neighbourhood is changing. I grew up on the other side of Nymark, near Shaughnessy, and we used to hike through the woods on the other side of Leslie opposite this project.
