Hello everyone!

I have a load-bearing wall in the hallway that I would like to remove. Currently, the posts are positioned so that the opening is about 1.2 m. This wall has already been supported by some kind of beam roughly 100x100, which extends along the entire wall that I've marked in red on the attached floor plan (not the one with the text description), all the way up to the bedroom at the top.

I'm trying to determine what I need to reinforce with to make it work. When I input the numbers into Byggbeskrivningar's sizing guide, I get many options, but I'm not sure which utilization factor and deformation are reasonable? I also don't know if their guide is well-suited to the conditions of this house.

As mentioned, there is already an opening with a 100x100 beam, so logically I shouldn't have to add another one as large as the one suggested by the sizing guide since it assumes no opening exists.

  • Wooden beams in an attic with insulation and a marked 100x100 beam, showing a load-bearing wall structure and existing support beams.
  • Floor plan showing a hall with a load-bearing wall marked in red, existing beams labeled 100x100, with dimensions 8610x4000 and limträpelare and limträbalk indicated.
