Plastering & Rendering

Use of plasterboard on brick/lime plaster

I have a large boiler cupboard (5ft by 6ft by 1.5ft) that has never seen the light of day. The flat is a first floor flat and dates from 1903.I wish it replastered before I have my new combiboiler fitted. The current plaster seems to be lime which has been applied directly to the brick with the help of only a very few laths. This plaster is about 3inches thick. The cupboard has one external wall. As mentioned always lime is breathable but modern plaster and plasterboard aren,t. If I was to opt for plasterboard what’s the best type and method to install to allay any fears about future dampness in this cubboard. Particularly on the one external wall. Should all the old lime plaster be removed completely back to the brick? Is there any advantage with respect of avoiding damp to leaving the old plaster on. ?The cubboard was originally constructed with 3 shelves which have been removed exposing the brick. Thanks Hardy man, actually it's a sandstone block of flats. So either theirs a cavity between stone and brick or it's been infilled with rubble.
