Help! Renovation of carpentry workshop.

[Forllin]

Hello all knowledgeable members!

I recently bought a small farm in Dalarna and now need your help with knowledge in certain areas where my knowledge is currently very limited.

In the barn on the farm, there was previously an active carpentry workshop. I now intend to spruce up the workshop and restore it to a fully functional carpentry workshop.

However, what worries me is the walls and how to fix them. Below you can see a picture of what the workshop looks like inside today.

Here are some pictures of the workshop's walls from the outside. On one wall, they have chosen to place panels somewhat haphazardly

Below are some close-up images of the walls from the inside. Is this something I can fix and if so, how.

Here below is a close-up of a problem! In certain parts of the wall, it sounds hollow when you knock, and then when using a rubber mallet and hitting the surface, it crumbles and falls down. It's as if the surface layer has bubbled up from the wall. I guess it is due to painting with a "dense" paint, causing moisture to get trapped between the base wall and the surface layer. What do you think?? How do I fix this?? Knock down all loose parts, clean the surface, and apply a new layer of plaster again and paint with silicate paint or?

Then there is also a larger hole in the floor in one corner of the workshop, which I don't really know how to level out. The height difference is about 10cm (Note: in the picture it looks like water has collected in the hole, but it's not the case)

I now need all the tips and advice I can get to restore this carpentry workshop to what it deserves! Thanks in advance for all tips and advice, I promise to keep you updated!

Is any wall located against the earth? When moisture penetrates the foundation, the plaster is corroded and becomes very porous. However, I guess it sounds hollow lower down on the wall = moisture is seeping up from below.

The hole in the floor should just be a matter of digging out a little, filling it with gravel, and casting some new concrete

Mightily jealous of your workshop!

The wall that sounds hollow is the same wall that has paneling on the outside! None of the walls are against the ground, and just as you mentioned, the hollowness should logically be at the bottom of the wall, but not here here, the hollowness starts about 140cm up the wall and is patchy.

Great, then I was on the right track regarding the hole in the floor!

Thank you, hopefully, with this, my pension in about 40 years will be secured
