Wow, I think I like modern and different buildings, but that accordion really is somethin' else. I think it would be more successful if it wasn't topped by something a lot more conservative and square and connected laterally to something different, conservative and square. Or if it were centered under the overhang. Or if it wasn't such a disproportionate amount of the total building mass. Or if it wasn't 80's black.
If you take that first faceted building, which is beautiful, as an example in the DC link, the faceting really dominates the building and is allowed pride of place. Not hanging out under a giant block. Also not that I'm a solar expert, but does a giant block overhang cut down on your solar efficiency?
I think a very unusual facade works best when it's a singular statement and really allowed to dominate or when it's an accent in an otherwise conservative building.
Put another way, the fun element should probably be like 10-20% of the building mass or 80%-90%. Here it's 50% of the one tower, and each tower has like two different and equal elements going on, so it just looks like two very different elements pasted together. My idea -- ditch the black and use colorful glass, add a bit more lean on the fun tower, center the block overhang a bit more, and make it look like a jack in the box!
In this building, 90% fun
