feels like the first real slender tower since custom house...
I think 1 Dalton fits that bill just a little bit better, particularly because it's the same width from every angle. When you can see it nearly top to bottom it appears very slender.
However, I definitely understand the sentiment here. It's funny to think how wide we all thought this looked in the renders, vs the reality of the nearly finished product! I am a very big fan of the way this building is turning out.
