Want to tear down an attic wall to make a larger bedroom. The wall consists of vertical planks about 2 cm thick and behind these are horizontal planks about 2 cm thick. It doesn't feel like it has a load-bearing construction. The wall is located about 40-50 cm from a roof truss with pillars on the sides.
Can I tear it down?
 
  • White paneled wall in a small attic space with a vacuum cleaner and some boxes on the wooden floor. Ceiling beams are partially exposed.
  • A partially dismantled knee wall with wood planks and construction tools in an attic space, showing renovation in progress.
  • White paneled wall in attic with adjacent timber beams, wooden floor, and visible ceiling slant; part of a space intended for bedroom expansion.
Hello and welcome to the Byggahus forum!

2 cm thick boards are usually never load-bearing. The term plank is typically used for timber that is at least 5 cm thick. I guess the house has a broken roof. In that case, the system of columns and beams carries both the upper roof trusses and the trusses at the sides.

Thank you! Yes, that's correct, it is a mansard roof.
This is what the gable of the house looks like, and here you can see the beams. The same beam you see in the first pictures on the inside. So is it that beam and the column you see in the pictures that hold it all together?
 
  • Side view of a white house with a mansard roof, blue window frames, and visible beams on the gable. A wheelbarrow and gravel are in the garden.
And this is how it looks at the top. I don't know why they placed those dark small beams there? Maybe to have something to nail the attic wall against? They aren't even attached to the sides so they can't be supporting either.

It is probably a fairly old house (before 1920 if it is not in the countryside...). Likely, the rafters/beams in combination with the pillars support the roof, but you can't be really sure without tearing off quite a bit. The wall of the cat room is not load-bearing anyway. It is a beautiful house, take good care of it!
 
Thank you so much for your answers! Yes, the house is from around the turn of the century. I am in the process of a renovation but preserving all the old elements.
