Fix holes in porous wall and fill the gap between the wall and the floor
Hello! We are beginners and don't fully understand the best way to fix our storage room, so we'd gladly accept some advice from you. We were thinking of applying a fine compound over the entire wall, but first we need to address all the drill holes that became quite large. We tried to remove all the loose material, but it just doesn’t end because the material behind the white layer is extremely porous. Do you know what this material is and what the white on the wall is, is it some kind of plaster? How should we proceed and what material should we use to fill the holes?
Then, when we removed a wardrobe, we noticed there wasn't any molding there and that there is a large gap between the floor and the wall in several places that we'd like to fill. What material is best for this and can the same material be used to repair the crack on the floor as well?
I was also very curious about a built-in box located in the corner of the room. It was quite large and in the way, so I was curious if I could build something smaller, and it looks like it. It seems like there are water pipes going to the bathroom, could that be correct? Is there any building code regarding hiding them, can something very tight be built around them with leftover MDF glued to the wall? Or does it need to be more properly done? What was there before was extremely overkill in my opinion, some kind of gypsum boards on top of a metal construction that were secured into the wall with huge screws and plugs.
Thanks for the tips!

It ended up being fine filler everywhere in the end. Wall? Fine filler. Uneven floor? Fine filler. 5cm hole where a brick was missing? Fine filler. Have filled a billion times, then sanded like crazy and accidentally sanded away everything I had filled, and then filled again. It became smoother than a baby's bottom. Going to build something around those pipes now.


Can't say I'm an expert on the subject, but I've done and would have done the same thing. It turned out nicely in the end too, well done!
