Will the cottage collapse if I tear down the plank walls?

[Acer767]

In an old thread, I asked about the cause of tar smell in my guest cabin.
I have now set aside some time to proceed with the issue - replacing boards on the interior walls.

The question is whether I dare to tear out all the boards at once.

The guest cabin is built with standing studs (about 45x70) c-c about 600 with overlapping siding on the outside and solid tongue-and-groove boards (horizontal) on the inside. About 35 mm thick.

The roof is a gable roof with concrete tiles on it.

I could use some advice here. Do I dare to remove the tongue-and-groove boards on the walls?
I think they are that thick for a reason? The concrete roof is quite heavy, it would be a shame if I redid it for nothing if the house were to collapse.

Someone with similar experience is welcome to reply - so I know how to proceed over the Christmas holidays.

I wouldn't hesitate to tear down. Is it floorboards? It's probably the case that whoever built the cabin happened to have some surplus 35mm flooring lying around somewhere and found another use for it. But you can try tearing down one wall at a time, install some temporary diagonal braces if needed.

It's the same type of boards that my old 1930s house is built with, so I don't think it's flooring. It's probably just really solid stuff.

But the tip about temporary braces was really good, I'm definitely going to use that!
