Semi-detached house with unequal halves = different floor plans

What could the fire protection issue be?

If there is supposed to be a window in the gable, then the boundary distance to another building applies, i.e. 3 meters due to fire protection. But that was just a hint from me. I do not expect any other advantages from rotating the roof.

We have not yet pursued a slanted house partition wall. I also have no idea at all right now how that could look,

It is enough if you are the only one scratching your head, without having a centipede next to you:

I'll attach a screenshot of the first height study

And now give the transept a "Frisian gable" that meets the gable of the other house. Then the transept has standing height there for a shower or headroom for a staircase, where before it was too low.

In the original proposal, the kitchen does not work as drawn.

Which of the two kitchens do you mean? – I do not find them convincing in either house, but they are probably still just placeholders in the preliminary draft (?)

In the smaller half, the kitchen works, but in the larger half there is only 60 cm of aisle space to the peninsula. However, if the peninsula is positioned properly, the dining area and thus the passage to the kitchen are completely restricted.

Yes, we noticed that too, it doesn't work at all like this. As 11ant rightly pointed out, they are currently more placeholders, but the floor plan as it is does not allow for a proper kitchen. We are working on it. In the front of the house, on the other hand, space is being wasted...
