Rising damp in bungaroosh house

Hello everyone

We’ve recently moved into a house in Brighton which is made of bungaroosh. It looks like the external render has been replaced with sand & cement. It’s likely that the external walls contain a slate damp-proof course. The internal walls are mostly gypsum plaster (although one of the party walls is plastered with lime).

We’ve had rising damp identified in some of the downstairs walls (including the lime wall). We’ve had conflicting advice - one recommendation was to have a damp-proof membrane inserted, and to re-plaster with renovating plaster. Another was to just replace the internal plaster with traditional lime plaster to let the internal walls breathe (and not to have any damp proof treatment carried out).

I’m a bit confused - is there any benefit to using lime internally if the external wall is sand and cement?

Any advice on how to tackle this would be very much appreciated! Thanks all
