Want to build a new wall above existing interior wall

[DarrenB]

I live in a 40s house with "kexvägg" that makes it difficult to attach things, and also new electricity is unattractively installed on the wall. I'm considering "covering" the old wall with a new inner wall where I put new studs, OSB, and drywall, and at the same time, build in the electricity more neatly. All the tips I've found here and on YouTube are about building a new freestanding wall. I just want to build over the old one. Is there anything that differs between building a freestanding wall and just building over the old one?

I live in a house from the 1940s with a "kexvägg" which makes it difficult to attach things, and additionally, new electrical wiring is unattractively placed on the wall. I am considering "covering" the old wall with a new inner wall where I can install new studs, OSB, and drywall while also hiding the electrical work more nicely. All the tips I've found here and on YouTube are about building a new freestanding wall. I just want to build over the old one. Is there anything different between building a freestanding wall and just building over the old one?

Now, I don't know what you mean by a "kexvägg," but it should reasonably be easy to build a new wall using this as a base. Then you don't need to have a strong construction. Screw a stud to the wall that's high enough to conceal your new electrical conduits (which are 16 mm). Then cover the wall with panels, maybe OSB plus drywall.
