Okay deep breath. Don't get me wrong, I really like this design and the city needs more original thought like this. BUT:
This design seems unresolved and incomplete now that we're seeing it take shape.
Podium: Amazing idea with the brick archways. Unfortunately, columns and pipes run straight through the windows, which make this look like a sloppy design that wasn't resolved correctly. I understand physics. I know that the columns are needed to support the building. What I am saying is that said columns need to be incorporated with the podium design with the archways to make the archways integrate into the building. As for the pipe? How is it good for anyone - CRU tenant, pedestrian, etc - to have a pipe running through the middle of a window? Finally, the varying width of the archways really grates my nerves. In design school you're taught the CRAP principle of design: Contrast, Repetition, Alignment, and Positioning. these archways execute on none of those principles.
Tower: I like the idea of introducing more brick towers in the core, especially in glass/spandrel-ridden neighbourhoods such as the Entertainment District. I don't think the designer paid any attention to the perceived weight that brick carries in this context, however. Bricks feel heavy, both visually and physically. Having a tower of bricks cantilever 100 metres above you feels imposing and unsafe, rather than inviting. It feels as though the bricks will collapse at any moment. Perhaps exchanging which sides of the tower are clad in brick could have addressed this, so the cantilevered side was glass-clad and the normal sides were brick-clad.
In short, yes, it is better than if the entire affair was covered in spandrel and mullions. It's a great design idea that should have been refined with a few more drafts before it shipped. I really hope the final execution can hide the flaws I mentioned.
