I am renovating a room in the basement that was previously a garage. The garage door was sealed in the 60s with some form of lightweight concrete and then framed and insulated with chipboards as the final product against the room. An exterior door is installed and will be retained.
The basement at that wall is about 60% below ground except at the door where everything is naturally dug out. Drainage was done 10 years ago with external insulation (the 60% that is below ground).
I plan to redo that wall with metal studs and new insulation but cannot find a clear consensus on how the wall should be constructed to reduce moisture problems and still be reasonably heat insulated. How would you insulate the inside of that wall? Should a vapor barrier be used above ground but not below?
The other walls in the room are plastered inside but lie deeper underground so I am not touching them. The room is quite cold as it is today but I will install a ventilated floor so hopefully, it will become somewhat warmer.
Grateful for tips and wise insights.

I didn't find anything either when I was building the bathroom.
I ended up only using insulation at the top and skipped it at the bottom, where it is already insulated from the outside.

Yes, that empty space, the insulation with cell plastics, and platon are on the outside.C citgot said:
Regardless of how you do it, it's a risk construction.
I have similar conditions and chose to build a metal stud wall which I insulated with 45mm rock wool. The metal studs are a few centimeters away from the hollow brick wall.
Finally, initially, I have passive ventilation of this space behind the insulation, slits with metal grilles at the floor and ceiling. If I encounter problems, I plan to install a small energy-efficient fan in one of these holes.
One might wonder what benefit the insulation provides if you're circulating heat behind the insulation, but I think at least I avoid having a wall that radiates cold.
On the metal studs, there is then OSB and drywall.
