To be fair, the select group of us who actually care about this kinda stuff will not be looking at the little podium with that schmexy tower behind/beside it lolloving the cladding on the tower, but good god does the lower podium to the north leave a lot to be desired.
I think my first diagram of CIBC got like...72? But I'm sure @steveve has me beat somewhere (and deservedly so, his 3D model is a triumph!!).
My limited Google Foo'ing has come up with that polyethylene sheeting comes in either rolls of black or white for vapour containing. So they must of wanted it for the ability to absorb light as oppose to reflecting it? Or it was on sale...I'm sure this has been asked and answered, but why are they using black tarp on the exteriors while it's under construction? I don't recall ever seeing a building in Toronto do this before.
