Bit unfair, at least at this point, as there's no cladding on the west facade...in the room.
Since this looks absolutely nothing like the renderings or Great Gulf’s project description: “ribbons of gleaming steel and luminous glass create a stunning façade”… I’m wondering if the gleaming steel will tacked on at some future date ;-).
I looked around for a rendering that remotely resembled what has been built so far, and only found this one from First Gulf:
Great Gulf render from the database: https://cdn.skyrisecities.com/sites/default/files/images/projects/15185/15185-63958.jpg
The first rendering shows fins on the south side (facing Cumberland), with no fins on the east side (facing Yonge). I can't remember seeing fins on the remaining 2 sides in the renderings. In fact, subsequent renderings show that the fins on the south side, which are supposed to 'fold' into slats on the underside of the overhang, are gone, although the slats are still there.Are they gone or just for the one side? Because that's not entirely a bad thing if it's with the latter.
