Plaster straight onto blockwork?

I've been stripping some horrible wall paper lining which has been painted in my sons room. This is the first room we are renovating in this house since we bought in April.

After taking a shelf off, some damaged blockwork came out which seemed to reveal that instead of plater on plasterboard which is affixed to the blockwork, the plaster skim has been directly applied to the blockwork.

Looking closer, there are cracks everywhere on the plaster once I remove the wallpaper lining.

I assume my only option here is to frame the wall out and screw new plasterboard onto the battens? Plaster skim over the existing plaster will probably just crack again won't it?

 
That's not a plaster skim. It's a render.

Probably a couple of options here. Dot and dab boards then skim or as you suggested baton/board then skim.

Going to lose floor space with batons and also need to consider condensate with a void behind batons.
 
Thanks all, why on earth would they not plasterboard the walls? It's an 1980's house, not exactly "old".

Think I'm going to batten it out myself and insulate the external walls whilst I'm at it.
