I was hoping somone could give me a bit of advice regarding a derlict
cottage I'm thinking of buying and renovating. It has a solid roof and
external walls but no windows or doors & also has no services
whatsoever (water/sewerage/electricty).

I was planning to extend it (it's tiny but in a good location).
However as the place is old (more than 100 years) it doesn't seem to
have a Damp proof course, it's built of granite blocks with lime
mortar (I assume) with a concrete floor inside.

What damp proofing arrangements would I need to make (if any), and if
I extended would I need to make any special allowances?

Any general advice concerning this proposal would be gratefully
received.

Damp proofing may not be required - it all depends. Out 70 year old
house, stone walled and rendered, with a cocrete floor inside, has no
damp proofing measures (that we've found so far).

When we moved in there was a fair bit of damp. But adequate heating and
ventilation, as well as fitting gutters and the like has pretty much
cured it.

So don't worry too much about the damp.

As for the services, you don't say how close it is to other properties.
This makes a big difference.
