If I remember correctly, my university constructed a new building for the architecture department but it was so impractical they gave it to computer science instead.
Unfortunately, this was in the late 60s, so the concrete they used turned out to be poisonous to plant life, so no vines ever covered the building, there were some sad scrawny things in a corner, but that's it. And the underlying building was of course really ugly, so, yeah, that was a pretty big fail:

Fact: the building was so ugly that it self-ignited.
