Great news but I had to chuckle at this statement:
The 14-story tower, 3675 Market, is being described as the “physical nexus” of uCity Square...
I don't have a big problem with the design in and of itself, but if you're calling this building the "physical nexus", give us something a little more worthy of that designation instead of just another bland boring glass box (that cute little cutout notwithstanding, it's still a box). Maybe not this building, but I certainly hope this massive project has one signature, well designed tall flagship building that distinguishes itself from the sea of glass boxes (I've argued the same thing for the Navy Yard).
Now, if this project gets totally built out without such a signature tower, I won't lose any sleep over it!
