I'm doing some demolition at home and I'm considering making a larger opening between the outer and inner hall. It's a concrete slab about 10-12cm thick that is cast on the blocks resting on the beam (green arrow). But it doesn't seem to have any weight resting on them.. can be easily moved with a screwdriver. I'm a bit uncertain if the concrete slab rests on the wall where the sewer pipe goes up but I'm assuming it doesn't.
Do you instinctively think it's risky to remove the beam (red arrow)?

Anyone willing to take a guess if it has any structural function for the concrete ceiling above?
I've removed the stones on top of the beam now so it's basically "just" to lift it away... but it still feels like I will replace it with some smaller beams like 2 pieces of 95x45 standing on edge on two pieces of 95x45 beside the sewage pipe and one on the left side... that is, they press up against the concrete slab. Good or bad idea?
Another option is to buy laminated timber columns 90x90, but a 5-meter one won't be enough, so it will be much more expensive...

Yes, the wall you are working on is probably load-bearing, it looks like the original exterior wall you are working on, the outer hall looks like an extension. If any beam rests on the part you want to remove, it can't be seen in the pictures, one must find out in reality.
Yes, that is indeed the old outer wall. The front door was in that opening several years ago, and there was another wall in front of it making it like a small stairwell, but it was so incredibly thin that it probably didn’t make a difference when it was removed.
I'm not quite sure what you mean by a beam resting on the part I want to remove? What rests on that part is the concrete floor, about 10-12 cm thick, and above is the rest of the outer wall, built up about 1.5 m, and then the outer roof rests on it. So it feels to me a bit like the wall should support well because it's a corner of the outer wall right there that the roof rests on, and the stones are built up above so that they support each other in a 45-degree line from both directions, so to speak. It's a bit hard to explain what I mean. But I’ll go ahead and we’ll see where it (doesn't) lead.

I believe it holds without a beam.
Trust me.
Trust me.
Perfect, then I'll send the bill Niclas because now I have half of the upstairs down here!! Just kidding... Now I don't know if you were serious but I think it will hold too actually.. just wanted to check if someone would come and scream NO NO but it doesn't seem like it?
Beams above door openings should not be removed without being completely sure if they are bearing any load. For example, how are the rafters positioned? Currently, the wall above might be arching over the opening, making the beam unburdened, but with a full snow load on the roof, the beam might be necessary.
Yes, that's pretty much how I'm thinking too, so I'll definitely add some reinforcement, but what that will be, we'll see. Hopefully, I have a month left before the snow comes.
Maybe it's just as well to use a slightly higher glulam beam like 180x42 and have two widths against the roof, so to speak. Or any other suggestions? I have at least planned to prop up the roof before removing the beam to be a bit safer that nothing goes wrong.
