Hello!
We have bought a house from 1969 where all the surfaces need updating. The idea is also to take the opportunity to prepare for new electricity, a few more outlets, etc.
The house currently has interior walls with particle board or some form of thicker MDF/masonite that is quite soft (curtain brackets sink into the wall when the screw takes hold).
One idea that has struck me is to install new interior walls on the existing ones. I’m thinking of framing with 28x70 or something similar. Then there would be room to run new electricity without adding as much thickness as 45x45 would.
But is this a bad idea? Is it better to tear down everything existing and redo it? I’m thinking that it might then require a new vapor barrier on the exterior walls, among other things?
Also, all the ceilings should be replaced since they currently have stretched ceilings with far too much damage.
Thoughts and tips are welcome 😃

Do you even have a vapor barrier in the existing walls?L Lijotege said:
Otherwise, maybe it's not a bad idea to install a vapor barrier (I wouldn't use a vapor retarder due to the age, etc.) and then frame with 45mm and run wiring + insulate. That way you get some extra insulation as a bonus.
Just check that there isn't an existing barrier/retarder so you don't trap moisture between two layers.
It might also be good to consider the thickness of the outer walls. So you don't end up with the wrong dew point and get condensation in the wall. In other words, if you have too much insulation inside a moisture-barrier layer compared to the insulation outside.
Very good thoughts. Thank you.
Unfortunately, I have no construction drawings of the house since we bought it from an estate. Only the plan, facade, and plumbing (what the municipality had in the archive).
But, it is mexitegel if that can be of any help when it comes to construction, vapor barriers, etc. Otherwise, I guess I'll just have to tear down a room and see how it is constructed. The surfaces need to be redone anyway, so if a room becomes a test room, so be it 😃

We've torn down as much as we can when renovating. Some silly things were done in the past that aren't really good today. Electrical boxes mounted right through vapor barriers, 2 outlets in an entire room, etc. Removing the surfaces including drywall, running new electrical, many outlets, conduits for network, etc., and then putting up OSB+drywall makes the rooms of a completely different standard. A lot of work, yes, but better to do double work properly than to keep fiddling with putting lipstick on a pigL Lijotege said:
In the end, it can be more work trying to make something uneven, damaged, or old look okay than to tear down and put up something fresh and new.
