Load-bearing wall? - some questions

[Alexandros]

Hello,

question regarding whether it is likely a load-bearing wall or not?

red circle: wall that was put up later than when the house was built. will be partially demolished.

blue circle: wall I wish to demolish. Do you think this one is load-bearing?

black line: direction of the roof trusses

In a red circle, you have a beam, so blue is most likely load-bearing.

In the red circle, you have a beam, so blue is most likely load-bearing.

I'm not a carpenter and won't do this myself, but I want to know the conditions.

The house is built without insulated interior walls, so they sound like drums when you knock. If I knock at the top of the wall in the red circle, it doesn't sound like there's a beam at the top. Nor does it seem like there's a column against the outer wall when I knock.

Could the column perhaps be in the outer wall and the beam up in the attic if it is as you say?

Is it a one-story house? What kind of roof trusses do you have? How wide is the house? Is there any sectional drawing? It might possibly be drawn with a wall as an "option" dashed in the red circle and thus no beam.

Is it a single-story house? What type of trusses do you have? How wide is the house? Is there a sectional drawing? There could possibly be a wall drawn as an "option" dashed in the red circle and thus no beam.

It's single-story with a basement. I think it says 7.75m in the picture. I don't know the dimension of the trusses, but the house was built in '68. I have interpreted the dashed line as an option or something like "possible wall placement."

Check if you have W-trusses or not, they are self-supporting, and thus no interior walls should be load-bearing.

Thanks for the good response. I will check this and involve a structural engineer to be sure.
