the north elevation seems pretty clear in drum118's photo ... in essence it is a flat wall with (a few staggering) windows, I don't qualify that as interesting as the south elevation
Wow, terrific shot - just as I imagined! The floorplans at 155 are drool inducing! Do take the time to check them out if your so inclined.
What level was that shot taken from? I'm a little surprised to see the Colonnade apartments so prominent from there, I didn't realize they were so high.
