we have a stone barn (rubble filled stone walls) which have had two walls pebble dashed with cement render on the outside and two that are not. I am looking to remove this if it is possible and then convert the barn for living accommodation. My first question is .. Is there are any views as to the best way to remove the dash so I can re-point and is this usually hard, is there a risk of stone coming lose or falling out? I was then going to re-point the outside and inside of the barn with a lime mortar to allow it to breath and therefore try to control the moisture. With this in mind I am unsure if it is then ok to dry line and insulate the inside knowing that the wall can breathe from the outside, I was thiking of using breathable insuation and rendering inside with lime mortar also or would the 1-2 foot thick walls actually give enough insulation if I have a very insulated roof put on and new well insulated and DPC’d floor put in?
any advice is welcome
