Thanks for the pics officedweller! I Haven't taken a close look at the building since the project started. Those dirty aggregate panels actually look like they cover the second floor of the building completely, maybe the second floor is just a service level, would be nice if they extended the upper facade down over the second mystery floor, I'm thinking of something similar to the podium level of the 1957 BC hydro building on Burrard where the bottom edge of the facade extends down past the floor plate. Adding a touch of visual interest.
The upper facade still looks crisp and clean, the proportions of the 50 year old spandrel are excellent.

What is the original name of the 60's mid bĺock building?
