How do I calculate which glulam beam is needed?
Asked the municipality several years ago and they had no plans.

Which municipality is it?
The municipality likely has drawings in its paper archive but is reluctant to look them up. -The order in the archives varies quite a bit between municipalities.
A constructor can probably determine quite well what type of construction the house is built from during an on-site inspection.
-The constructor might also be able to put more pressure on the municipality if drawings do exist after all.

We do not want to involve any constructor, or else I wouldn't have asked here. Instead, we would prefer to over-dimension or make the opening smaller.
Only the floor in the drawing is furnished. Above is just the attic and below is the basement.Sockerhög said:

It plays quite a big role what type of municipality it is. Cities have had the requirement to keep track of building permit drawings since 1874. Rural municipalities only since 1947. An exterior photo can say a lot.
This is in the countryside

The image shows that the porch roof is half resting on the current wall piece. To be able to calculate a beam dimension with some accuracy, a detailed description of the conditions is required. Since you lack drawings, there are two options. One is to measure the house and, based on that, make your own drawings. The other is to document the reality with photos (interior and exterior) so that one can understand how it is built. Or a combination of both options.
Just let me know exactly what I need to photograph and I'll take care of it. I've measured a lot over the years but maybe not what's needed here.

Ideally, I would like to see floor plans of the ground floor and attic, as well as a section (cross-section) through the entire house in its current state. Additionally, photos from inside the attic showing the dormer, and from outside showing the facade above the veranda.
There are no other drawings than the ones I posted. The attic has only one staircase up and then a dormer. The wall originally consisted of threetex, 17mm tongue and groove boards, 65mm planks, and panel. Now there are additional 95mm studs on the inside and double 45mm studs on the outside. Taken a lot of pictures of most things, if something is missing or needs to be explained, just let me know.

I had thought that you would make the drawings yourself... The images still show that a large part of the roof loads go beside the point of deviation. I would like to think about it for a day.
