Hello! We have started opening up a section between the kitchen and the living room. Now to the problem, when we opened up towards the outer wall, we accidentally opened a bit too far. Because pipes run there that we thought went a bit further out. Now we need to build back a bit so the wall is level with the end of the pipe. How do we do this in the best way? Anyone have any tips?
According to the image below, we need to add 20 cm.

Thanks in advance!
 
  • Partially opened wall with visible pipes, adjacent to a tile floor and parquet flooring; a purple ball and crowbar are nearby.
Hey! Oh, that kind of thing happens easily, luckily the pipe was fine. The simplest thing is probably to build up a wall there and let the boards on the wall pass by on the outside of the old wall, if you know what I mean? The problem will be securing the stud at the outermost point outside the pipe. What kind of floor is there at the joint that's torn up? Maybe you could fasten an angle bracket on the floor there, which you can then attach the outermost stud to. If you place the boards on the outside of the old wall, you only need one stud on the outside of the pipe. Then put a layer of plywood and then a layer of drywall on each side.

Thank you for the response, it looks like there is also lättbetong on the floor.
 
Okay, does the wall continue to a floor below otherwise it should be concrete there? But you can still try to secure an angle with lightweight concrete screws or plugs. Plywood is not a must (considering today's prices) but the wall becomes more stable with it plus if you want to attach something to it later.
 
Yes, it seems possible to attach the beam with concrete screws. Plywood plus gypsum sounds like the safest option to go for! Thanks ☺️
 
Can't the pipe be replaced instead?
 
I had checked if it is an expansion pipe for the expansion tank in the attic. If the tank in the attic is disconnected, you can remove the bends and possibly also the pipe. If the tank is used, it can be replaced with a pressure tank in the basement.
 
That looks like a drainage pipe, do you have a bathroom on the floor above? If not, it might go up to the ventilation on the roof.
