I’ll be honest. Ando’s work may not be going to spall and collapse in a heap, but it is still ugly because it ignores the decoration issue. Something that I find hard to understand when Japanese buildings all around his ones have decorative points.

However thanks for explaining the various reasons Brutalist buildings are bad and that they are not intrinsically connected.

I’ll add one other reason they are often bad, which is that they either expose all the wiring and plumbing or they are a maintenance nightmare where a blocked drainpipe is next to impossible to fix and pulling, e.g., new ethernet wiring is impossible without major disruption.
