Division of a semi-detached house along the roof ridge

I do not see any technical challenges in a division along the roof ridge.

How this can be sensibly represented in the floor plan without ending up with tube-shaped halves is another question ...

Here, a site plan with the surroundings might be helpful.

Hello I know what you mean and I quite like it too. But the OP is asking for something like this: "only a semi-detached house is possible, where the division is along the ridge of the roof."

So a normal, but somewhat larger house? I don’t understand the problem with imagining that and assume that the development plan gives the OP too much creative leeway, so it might be misinterpreted or simply no other options are visible for themselves. No idea. That’s why I’m specifically asking how it is to be understood.

I understood the original poster like this. Picture left.

You like picture right.

Now it depends on the developability.

That's how it is... with two words and characters

Good friends of mine live in such a semi-detached house with 1.5 floors + basement. And yes, the house is long and narrow and has a lot of slant upstairs. But they solved that with a clever floor plan and installed dormers upstairs, so that it works really well overall.
