House renovation/Loft conversion/What is allowed? From when can a loft conversion begin?

Once again for understanding:

Is there a difference between a "Dachausbau" and a "Dachgeschossausbau"? Or is it really exactly the same?

This question should be answered by your building department***worker. Even if I write here: It’s the same for me -> maybe it’s handled differently where you are and you’ll get approval for your 2 rooms? Basically, it’s about you wanting to use the attic as living space – according to the development plan, that is not allowed. The administration doesn’t care how you create the living space. But maybe you will get approval? It’s always worth a try – talk to *** your building department – they will help you.

Hello,

To clarify once more:

Is there a difference between a "Dachausbau" and a "Dachgeschossausbau"? Or is it really exactly the same?

The first word corresponds to colloquial usage, the second to correct construction terminology. In construction, only the difference between attic and loft is made.

Hello,

But I still hope that there is a loophole. After all, we just want to create 2-3 rooms. No dormers, no raised knee wall, no other changes. Just a roof pitch increase to the allowed extent!

There is a bit more behind it than "just" raising the roof pitch to the allowed extent. The ceiling above the top living floor will probably not be a concrete ceiling, nor a collar beam layer designed to support living spaces. A simple floor hardly needs to be designed to support loads if it is only going to hold decorations & co.; but if technology and furniture are added, the structural engineer will certainly see it differently.

If your municipality denies this for your location, they will have had reasons for it. I am curious about what information you will receive from the building planning office.

Rhenish regards

Thank you! We will now get an appointment at the building authority and present our concerns.

@Bauexperte: Actually, the floor is even covered with screed. So the load-bearing capacity should not be an issue. However, if it were possible, we would have a structural engineer come anyway because we want to remove a few walls on the lower residential floor. But so far, that's all just speculation. Now we first clarify what we are allowed to do and what not.

If you're interested, I'll report the result.

Best regards
