Tearing down interior wall in own house 1937

[Niklas Bromma]

Hello.
We have a house in Norra ängby (same as Tallkrogen). Egna hem type V. We are going to try to tear down the wall that is red on the drawing, which I believe is a hjärtvägg. Anyone who has done this and has tips on how you did it? Could it be the case that it has no load-bearing function and you can just tear it down straight away?

The easiest way is probably to take a look in the attic and see what type of truss it is.
Take a picture and post it here, preferably with a description of the construction and dimensions, so you can surely get good help from our knowledgeable constructors here.
Is this in the Stockholm area?

The wall definitely needs to be reinforced. Free-standing trusses were not common when the house was built. To calculate the beam size, it is good if you do as KnockOnWood suggests.

We live in a V:33 house and have torn down the walls marked in red in the post below https://www.byggahus.se/forum/threads/baerande-vaeggar.291419/

I had Patrik from Norra ängby bygg come over to take a look, and he said that none of the walls on the upper floor are load-bearing.

However, in consultation with a relative who is an inspector, I have chosen to reinforce the rafters with longitudinal 45x195 beams mostly to be sure.

Be careful when tearing around the chimney stack, it's common to find eternit as fire insulation there.

With a span of almost 7 meters, only truss roofs can be self-supporting. I think that was unusual, but a photo from the attic tells a lot. Even if they were self-supporting when the house was built, the snow loads might be underestimated.
