I have a little question!
I am thinking about framing a section of an exterior wall, as well as insulating, etc.
How do I handle the "vapor barrier" in the existing exterior wall? Should I open it and remove it, then place a new one inside the new wall I am building?
The wall is about 1 meter wide and 0.2m deep.
Grateful for an answer.

Doubtful if you have anything, so a guess would be that you don't have plastic in the wall. I would probably still tear down the old wall panels and check the existing insulation to make sure it is good and intact without cavities. But it depends a bit on the construction, for example, Hultsfredshus used fiberboard for a while, and then you can install framing directly without removing anything. Personally, I wouldn't install any plastic in the wall for this type of additional insulation, but rather OSB+Gypsum on the wall. And make sure you don't have any gaps at the ceiling and floor, it should be airtight. Depending on the type of foundation, I would check how it's insulated in that area. In our 1960s house with a basement, the floor joist wasn't filled against the exterior wall, and it was noticeable that it was colder on the floor. So during renovation, I took the opportunity to open the floor by the exterior wall and filled the joist towards the exterior wall and 600mm inward, which is half an insulation board, but only in conjunction with replacing the floor. It made a big difference, especially where we had corners with two exterior walls.
