Floor plan: Semi-detached house 8x12m. Opinions and creative ideas welcome :-)

In your planning area? - then the worst-case threat for you would be very real. Hopefully not. Although it can be built, then grandma has to go to the attic

I'll be positive and say "I'm just faster"

You mean house number 33? But there the plots are at least 13m wide. Allowing builders this freedom with 11m plots would be irresponsible in my opinion. Well, we have developers here who have already built 5m huts several times. That works too.

No, the area goes even further. But yes, I definitely agree with you. It would be irresponsible...

whereas I have to say that I did not understand Yvonne's explanations. But it doesn't matter, since the situation here is clear. I even suspect that the person who commissioned the land division also has corresponding building encumbrances

I admit that I have not read the development plan here.
My parents' house was probably a bad example, since not all facts can be seen.
Well then.
I will stick to my opinion that taking only the other plot would have more advantages.

I admit that I have not read the development plan here.

Neither have I - was it ever even mentioned?

has this even ever been mentioned?

Not here, but there are other sources that you like to refer to. It's already two and a half months ago - but what kind of an elephant is that.

I admit that I have not read the development plan here.

Not here, but there.

Max. 2 full floors

Where does it say that?

Where does it say that?

So it says there
"In buildings with two full stories, the construction of a knee wall in the attic is not permitted."

This means, conversely, that it can only have two full stories if no knee wall is allowed. (With a wall height of 4.70m and a maximum building height of 9m)

It means conversely that there can only be two floors if no kneewall is allowed. (With a wall height of 4.70m and maximum building height of 9m)

No, I don’t see it that way. The development plan does not specify the number of floors. But what I think of that "thing," I have already described in green colors.
