Tear down wall...load-bearing???

[blekarn]

I'm considering opening up between the kitchen and living room... and I'm a bit unsure if the wall is load-bearing or not. The span of the roof trusses is 7800mm and they are of the truss model. The wall only has 70mm studs. What do you think?

I would think it is load-bearing, you can put a glulam beam in the ceiling before you tear down the wall. I have 6500mm between the posts and had to have one in the ceiling when I wanted it open between the kitchen and living room.

Have you seen that you can also place the glulam beam in the attic? Sometimes it can be simpler. Check out this thread.

Yes, a glulam beam in the attic could be an option... having it inside is not an option, then the feeling disappears, it seems.

I think it's tricky to give advice on this. But it's entirely possible for truss rafters to be load-bearing over 7.8m. We ourselves have truss rafters with an 8m span on part of the house.

Even if the wall is not load-bearing, it may still support "a little", meaning if the rafter rests on it, there is a risk of additional deflection, which could potentially lead to settlement cracks.

drawing a parallel to our very old house.
we opened up a wall like a "window" when we began to handle it carefully, it turned out that
the wall that wasn't load-bearing from the start had become so after all the years it settled and a few renovations.
so open the wall and check if there is "pressure" on them, don't just go with the saw directly...

a small picture goes our renovation with this particular opening

and this is how it turned out with the new wall and kitchen
