I've worked in one, at Case Western Reserve University in Cleveland. The Peter B. Lewis Building: https://weatherhead.case.edu/about/facilities/lewis/default

Among other problems: (1) no provision was made for the fact that Cleveland gets snow and ice, leading to barriers for pedestrians to avoid their evisceration via detaching ice sheets from the curved roof, (2) the glare off the roof is focused straight down a nearby street @ 5pm, creating driving hazards, (3) it's difficult to navigate internally from one side of the building to the other.

Most star architects are hacks, coasting one step ahead of being made to answer for the flaws of their previous projects. The more famous the architect, the more they feel obliged to ignore basic design.
