Thanks for the tip. I've looked at Back to earth and will definitely speak to them.

@Mr PunterThe metal roof is being replaced by slate tiles and the pointing re-done with lime. We wouldn't want to knock it down as we love it as is, just want to make sure we look after it properly. We haven't asked if we could knock it down but as they are being so strict with conditions we have assumed it would be no. @Redbeardthanks for the advice

Not allowed, it's curtilage listed

Solid stone stable building in a conservation area. It has taken us 2 years to get all the planning. We live in Singapore currently and are doing this remotely with a project manager. Our conservation officer has insisted we ensure the building is insulated with breathable products - being totally naive about everything we are now doing the research we should have done before! It seems our PM was happy to use modern methods, having done the research we realise this is not necessarily the best way. Hoping to find more help on here....
