I hope this is the most relevant section I am posting this question in.

I am going to buy a property in South Wales, probably Glamorgan, Carmarthenshire, Brecon, Pembrokeshire and usually go for a brick and block cavity wall and concrete tile type property.

There are a couple of properties I like the look of that are built with Welsh stone and slate roof.

Do any of you know if they are built with a cavity or a just 1 thick stone layer?

Are they harder to keep warm in the cold weather and are they susceptible to damp on the internal walls?

Look for the EPC report on the different houses to estimate the running costs of heating.
Damp can be a problem in any property, Stone houses are solid wall construction so are susceptible to more damp than cavity wall construction
your surveyor will provide a report on any damp issues
