I don’t want to argue here about ancient history, as we are both correct. I am rather referring to comparable scale and style. It is true that renovations are often added later in gaps between buildings.
You’re not reinventing the wheel—rental buildings (and others) were constructed differently in the past, especially due to restroom layouts compared to today. But basically, houses were designed in relation to the neighboring buildings.

In particular, the point was that the original poster’s focus on the interior of the house in terms of size, function, and features should not be overly influenced by the exterior appearance.

That's how it is.
I don’t really understand why this is being made such a big issue now, since ultimately the building authority decides.
I actually had the impression that the architect succeeded well in making the upper full story appear like a gable roof, at least from the side.
