42, I'll take a look at it in person. Because you're right that one really has to actually see it to truly "see it". But in the meantime:
1) The brick matching is not really close at all, at least in the photos. Somehow other developers manage to do much better. I get that from a heritage perspective, one doesn't necessarily want the old bricks and the new bricks to look too much alike, and I don't mind the way that the bricks in the new addition at the rear distinguish it from the historic facades towards the street. But the brick surround for the door is just jarring. I'll reserve judgment until I've seen it in person, but from the photos it looks like a poor replacement for what was there. Such a clumsy change.
2) When you say that the warehousey look appears to be the back of Shoppers, are you referring to the door to the loading bay? (Interesting, I don't mind that as much - it's in the new addition and is kind of unavoidable) I was referring to the new residential storeys above the facade, closer to Queen Street. Poorly executed.
