I have already largely torn down a knee wall, see the pictures below. (Removed the horizontal tongue-and-groove boards and left the standing load-bearing (?) studs for now.) Considering the drawings + the fact that the corresponding load-bearing function does not exist on the other side of the room, I assumed the wall is not load-bearing. However, now I think it all looks too solid not to be load-bearing. At the same time, construction was a bit different back in the day (the house is from 1909, the drawings are from 1937)...

Is there any way I can figure out if the wall is load-bearing? If it turns out to be load-bearing, I will, of course, chase down a structural engineer to calculate it! The wall in question is red-dotted.

Along the elevated wall line, there is a horizontal beam with bolts at uneven distances. This solution is not present on the other side of the room, where it looks more "normal"... I suspect this solution is putting a damper on the dormer project. There is currently a dormer right opposite, see the drawing. Maybe a skylight instead...

My internet connection is acting up a bit at times, so sometimes the pictures above might not load properly. However, it should only last a minute or so every now and then!

Thanks in advance!

Just had a structural engineer over who confirmed that the wall has no load-bearing function :)

Searched a bit in the Yellow Pages and found one who lived just 500 meters away. Didn't even want a cup of coffee for the help, anyway a very nice older gentleman  :)

It really looked like stud walls... but when you look at the floor below, you don't see a wall in the same place, so it cannot be load-bearing.

What theory did the structural engineer have...? Or did he say no as soon as he entered the room?
Best regards, me
 
I have the same construction on our new build.
This attic wall can thus be part of the truss framework.
