Ugly and will be dated the instant it is occupied. Literally just doing things because we can at this point. Not graceful at all, the BKL mega proposal for Shenzen, H700, is stunning:

Seriously though? Interlocking volumes? It's like the designers of this Nexus tower heard that phrase one time in architecture school and decided to design a 2000' tall building around it. Why? Is there any logic besides "it's cool"? They even made a fancy animation showing how to chop a volume up into interlocking volumes, but it is not showing anything. Like why did they even make that animation? What information is that conveying other than "this is how the building could have looked, but we made it look this way instead"?
Hopefully for the residents of Shenzen the H700 design will be build so it can completely overshadow and distract from this baroque garbage.
