Demolish moldy basement

[Kenstarfighter]

I am currently demolishing our basement which is water-damaged.
The problem has been that there were wallpaper layers at the innermost part and that everything was built with wooden studs, insulation, masonite, etc., without ventilation.
I have found some mold behind the walls but am wondering.

Do I need to tear down the ceiling and also a wall that is not outward against the exterior walls but is connected with an exterior wall in the corner?

They don't appear to be affected by mold but maybe should be removed as they are also made of organic material?

Hadn't left anything behind, what will you use the basement for later?

Wouldn't have left anything behind, what are you going to use the basement for later?

Renovate it so we can have bedrooms, a computer room, etc.

Congratulations on the basement, an invaluable asset!

It's best to tear everything down. That way you get rid of mold spores. What type of ceiling do you have?
I would be skeptical about a permanent bedroom for two reasons:
Basements are not built as living space, and you never know what indoor climate you'll get.
The small windows are not suitable as an escape route.
I've had and still have different basements with various characteristics, so I know.

It's unfortunate about the skin condition on the left leg.

I think it's a tattoo, too bad about the poor eyesight ;-)

There are wood studs in the ceiling.

But I think I'll make the decision to tear everything down.
It should be the safest thing to do anyway

The strangest thing is that as the previous owner, you have installed a nivell system just because the slab is uneven; you haven't used it for ventilation as it's intended for...

If you had just been smart and used the material as it's supposed to be used, you wouldn't have to throw out the nivell beams because they might have gotten mold spores on them...

Nivellation beams are (according to themselves) made of heartwood pine and should not mold. I would probably reuse them after cleaning them with something like Jape Mögelfri. That is, leave them there and clean them.

Nivellreglar are (according to themselves) made of core pine and should not mold. I would probably reuse them after washing them off with something like jape mold-free. So, leave them there and wash them.

That would be ingenious if so. I've cut off some to easily remove the masonite, but if so, you'll save a lot of money. I still have about 80 sqm left that I haven't touched yet.

It's not entirely uncommon to have Nivell without ventilation, is it? We've looked at two houses where they've installed Nivell just in case, but not ventilation.
