Hello Everyone!

Sitting in an old brick house with plastered interior/exterior walls. Unfortunately, the plaster has started to become really poor on the inside, which results in it being almost impossible to put up curtains, etc., without using chemical anchors, etc.

I was thinking about whether it's possible to put up some metal studs on the inside and attach OSB board and 6 mm gypsum to it, thereby creating a surface that can easily hold pictures, curtains, etc.

Another big plus is that it can easily allow the electrician to add new outlets without chiseling into the plaster...

I'm mainly worried about potential moisture migration and getting condensation inside between the plaster/OSB.

I feel a bit like I can't be the only one trying to get rid of my otherwise poor interior walls...

What does the expert panel say, can you do this without risk of moisture, etc.?

you can put plaster on the render, right? possibly osben as well.
with sheet metal, osb, and plaster, it builds at least 5cm.
or do you want to make the wall vertical?
 
It is quite vertical as it is currently, mainly thought about making room for things like electrical boxes, getting rid of old feeds to the radiators, etc.

Okay. Think it's boring to cover surfaces with metal, OSB, drywall.
 
Yes, I think so too, but considering that the plaster doesn't hold, and that we need to "build" the number of outlets in various forms, it feels like a sensible solution. However, it's only the exterior walls that we/I plan to do this on... considering they're already 530mm, it doesn't matter if they go up to 580mm :-)
considering it makes life much easier for the electrician and for me who will be installing network, audio, and other technical "gadgets".

do you know exactly how the wall is constructed?
is it brick, wooden frame, reed mat and plaster or brick all the way through and then plaster?
 
Have got a little understanding at least.
This is what it looks like from inside what I believe and hope :-)
Plaster->Brick->Air gap->brick->air gap->facade brick

The outermost layer was applied sometime in the 70s and is ventilated from outside, the house itself is from 1909 (if I remember correctly)

The house stands on a ventilated crawl space which, by the way, is bone dry.

what a combo.
should have put insulation in too (when you frame up, that is)
 
then the question is whether one "should" insulate from the inside.....I have also been thinking about insulation but the question is whether the wall must be ventilated due to the moisture present in the plaster....
