House purchase, illegal attic expansion? Dismantling?

You are not allowed to ask such things in forums because the [Millimeterhermänner] immediately take over the topic. - Yes, life is dangerous, ends fatally, with luck without dementia beforehand, and you can also die in fire.....

A colleague bought a condominium with a roof room. However, this was not approved and is not permissible and no longer accessible. There was a cease and desist order regarding this. There was no second escape route.

This is the case with a multi-family house, not with a single-family house. These are two different things.

I wouldn't care one bit whether approved or approvable. Just be happy about the room. If a TV and a couch were in the basement, it would be just as good and no one would ask.

It would be the same for me, as long as the rooms are not included as living space or such in the purchase price. I forgot to mention that, in the end many attic conversions are simply not approved. But that doesn’t really matter at first.

A property never has a price per sqm, but a market price. And if that is correct, the house is gone, whether with or without a [Panelstube unterm Spitzdach]. K.

In the case of a multi-family house it is like that, for a single-family house it is not. Those are two different things.

That is not correct, I am building a single-family house and it is a requirement!

What is supposed to be illegal about that? Using the attic peak as storage space is completely normal. Where is the boundary of the "development stage" from storage space to living space supposed to be? Raw OSB boards are okay, pressed panels not?

The final use is then another matter. When I see the bed there, I already know how the previous owner mainly used it... "TV room," yeah, right.
