I'm hoping that when the building is finished the seventh floor will just look like a subtle wave that actually enhances rather than detracts from the facade. We'll see. It could also just look like a mistake.
I just calculated the height of this thing btw. The original structure was 48 meters with 13 floors. With the addition of two office floors plus the rooftop floor with the height equivalent of exactly one more office floor, plus about a meter rise about the outer walls for the photovoltaic roof. That puts this puppy at about 59 meters.
