New concrete floor in an old stone building: rip it up????

[mddh]

The house is about 120 years old, stone built, with probably no dpc at all in the walls.

The previous owner (deceased so no info available) had a whole of the ground level floor (which was originally normal wooden floorboards over wooden floor joists construction, apparently rotten badly in places) replaced by a concrete floor about 4 years ago: screed/aggregate, membrane, concrete, then ''floating floor' made of chipboard on top. We are not quite sure what exactly was done and it seems impossible to find out (no paperwork was provided).

We are concerned about the effects of such a floor on the stone walls - lack of ventilation + moisture travelling into walls (which are damp anyway as partially rotten v-lining certifies). We'll be stripping off the v-lining that covers all of the interior, but are also contemplating ripping up the concrete floor and putting back the joists/floorboards.

Does it seem reasonable or completely OTT? Is the risk to the walls/house structure from such a floor something we should worry about?

And if not, should just the chipboard come off (we almost certainly don't want that, especially as it will likely go to mush with any water on it).

This is my first post, so please do go easy on me. Thanks!

Don't see the point in ripping up a concrete floor and going back to suspended timber. Are you sure it is concrete slab directly under the chipboard? Don't see why you'd stick chipboard on the slab unless it was a poor finish. any sign of a dpm in the floor somewhere? Sometimes you can see it at the edges. Would have been a pretty bad builder not to have even used a dpm.
