Ok, that is what I had thought, just wanted other opinions

I'm renovating an old cottage with ragstone dividing wall to next house. There's no evident damp or humidity problem. The walls are built with lime mortar joints and what's close to mud internally (?) I'm thinking of lining the internal kitchen wall with OSB so that I have better fixing for wall cupboards. Any advice welcome - should I put a vapour barrier behind.
