Hello
I'm thinking about tearing down an entire corner of our extended house. Unfortunately, those walls have a large dormer on the extension. It feels a bit heavy to solve with glulam beams. I should probably mention that I plan to knock out the walls to install glass doors on the ground floor, so it's not possible to support more than at the attachment points and the corner, of course.
It's a corner where the walls are about 4 x 5 meters in each direction.
I was considering that maybe something like an H-Beam would solve the problem since the span that the roof trusses rest on is quite long. It's the longest wall that the roof trusses rest on. The house is on a foundation made of concrete & the walls & floor are made of lightweight concrete. My question, which I hope someone has a good answer to, is which construction one should look more closely at & where one can get a calculation for the beam needed.
It would be bad if the house tipped over

You need a constructor/building engineer who can get an assessment on site. What I see is partly the pressure from the roof trusses but also the pressure from the remaining pillar. It will press very hard on the surface.
Not sure the house will tip, rather think it's more likely to collapse
Joking aside, I get the impression you also have an upper floor, which should complicate things. Additionally, it's built in lättbetong. I imagine it would have been easier if it were wood. Contact a structural engineer who can calculate if this is feasible.

perhaps o-beam (square) 6mm x 100 x 100 attached to 300x300x8mm iron plates at the bottom, and taking one in the corner as well as at the attachment points and one in the middle of each wall. In total, it involves 5 posts each 100 mm thick, it's not so outrageously conspicuous. It should hold...
Hehe, harder than that. No posts in the middle of the intended blown-out walls. I actually believe in something like an H-Beam 200 x 200 as both legs & top rail. Pressure plates on each leg at the bottom (i.e. 3 pcs) would be the safest, but I could also imagine sawing out the siporex where the posts are to stand so they bottom directly into the concrete beams that the torpar foundation consists of. There will be about 3 roof trusses that will have no support under them (just the beam), if that beam bows under the pressure there is the wrong beam. Of course, it can give 1-2 cm in the middle but that shouldn't be any match for the intended beam.
Under the house, the concrete beams rest on a number of concrete plinths that support the entire torpar foundation. The important thing about the appearance of the entire construction is that it becomes completely clean without lots of visible supports except in the corner, of course. That's the challenge, so to speak... it will look incredibly cool with the large dormer on top of the large sliding glass panels... hopelessly, I'm getting so tempted now.
