freezing causes plaster to spall. a unheated room probably wouldnt be
a problem if its part of a larger building, that leaks heat to the
unheated space



Freezing doesnt cause it, water freezing does. I have zero damage on a
110 yr old cottage kept unheated every year in zone 5, -15f. Think
summer lake homes, there are lots of them here, so lets all talk from
personal experiance, not second hand stuff where you have no idea of
what condition the roof and systems are that you neighbor had. Any
leak will make a big mess in winter everywhere in the home.


The OP inquired about keeping one room unheated, very different than
uniform temp/humid.
In an occupied home, moisture from cooking, showering, etc., would
likely condense on
surfaces in the unheated room If wallpapered, it might cause peeling,
staining, mildew.
If enough condensation, might also harm woodwork, doors, paint, trim.
