We are renovating our semi-basement in a house from the 60s. We have torn out all the wooden studs and internal insulation in the floor and walls. It is insulated with isodrän on the outside. It is dry but there is a hint of moisture at the bottom of the floor against the outer wall. One wall against the outer wall has been covered with natural stone. For load-bearing interior walls, we are considering using steel studs and Half-buried basement with bare block concrete walls during renovation, debris on the floor, lit by a bulb. moisture-resistant drywall, then plastering/painting over it. Is this a good idea or are there better solutions?
 
Applying plaster directly onto the wall is probably the safest solution.

Alternatively, use metal studs with boards on and ventilation of the space behind.

The downside of framing and plasterboarding is that the massive feeling disappears and you get that hollow sound.

The better alternative would have been to chase any electrical wiring into the walls, then plaster the walls and paint with an appropriate vapor-permeable paint.

But if framing and plasterboarding are absolutely necessary, skip the moisture-resistant plasterboard and go with the regular type, leaving a small air gap at the top and bottom.

Thanks for the tips! I think we'll skip drywall and go with plaster and paint with plaster paint.

Thanks, I hadn't thought about the different feeling with drywall and the different acoustics. Both look nicer with plaster and are completely safe.
The floor will be tiled.

Considering laying lecablock 75mm against the other exterior wall with a window. Is it unnecessary? Can you plaster directly?
