underground architecture built by animals who never took a single design class

means To dig a tunnel or hole in the ground, or the actual hole or tunnel an animal digs to live in.

from From Old English 'burgh' / 'beorg' meaning a fortified place or shelter — the same family that gave us 'borough' and the '-bury' in town names like Canterbury. The thread running through all of them is the idea of a protected, enclosed refuge; a rabbit's burrow and a walled town turn out to be linguistic cousins, both places you retreat to for safety.
