aside from the obvious of water pipes freezing, can cold damage a house? I
don't know what might occur, wallpaper peeling or plaster cracking or
whatever.

It is not low temperature that damages houses, it is damp (moisture.)
Damp varies with humidity, i.e. at low temperatures water vapor
changes from a gas into a liquid (droplets or ice.)

If damage can occur, at what temperature would it occur? If I keep am
unused
bedroom closed up for the winter with the radiator turned off, can
anything
bad result?

1. Probably not.
2. But you can open the door and look (and sniff too) every two weeks.
