Is the wall load-bearing?

[Csv7]

Hello, I wonder if you can help me. Is the wall load-bearing?
I am including a drawing from 1961.

The wall to be removed is between the (old) boiler room and the (old) garage. The garage was insulated and converted about 25 years ago, so it's furnished, etc. Now we want to open up between the (old) boiler room and the guest room/old garage.

The house has a wooden frame and brick veneer on the exterior. It is a single-story LB house from '61.
See drawing below.

I would think that it is load-bearing.

I would think it is load-bearing.

I do understand which walls in the rest of the house are load-bearing, etc., heart wall and so on. But here it is a smaller part, separated from the rest of the structure and not as high-ceilinged, etc. Unfortunately, there is no hatch up to the "small" attic above the garage, so I cannot check that way...

Yes, it's the truss construction that determines it. Is it a flat roof there?

No, it's not flat, it's a gently sloping roof with fiber cement tiles.

Hello again, after some work on the roof, I have a small opening to look up into the attic above the wall I want to take down. It seems to me that the truss is NOT resting on the wall construction, but "floating" some decimeters above? Also, the wall I want to take down is in line with the trusses, so it seems unlikely that the wall would have any supporting effect on it... or what do you more construction-savvy people say?

If it hovers in the air above the wall you are going to remove, that is a good indication that it is not load-bearing. Then you need to consider whether the outer wall will still stand firmly when this inner wall disappears, probably not a problem.....
