Dry wall

daffandil

Hi Folks, we've recently moved into a old stone walled building which is quite damp top, bottom and walls, we will be changing the floors, repairing the roof and digging a trench along the outside wall of the house filled with gravel,etc. The outside western wall is cement rendered, inside the house we have removed it with the intention of putting hemp plaster. When a builder friend of ours saw it he suggested to simply stick plasterboard onto the stones and tape the joints. I think it is called dry wall. He says also to cover the outside wall with mineral slabs. He says the plasterboard needs no insulation, I'd like to ask your advice on this, what do you think?

Some very bad advice.
Putting in French drains is a good idea. All the cement plaster should be removed and re done with a lime plaster. Hemp/lime plaster is a good idea but you must get someone that knows how to do it. Dry lining stone buildings is a proven disaster and you should Google http://www.josephlittlearchitects.com/papers.html.
