Hi Ganner,
Thank you very much for your detailed response. Really great!
Yes, the plot on the right is undeveloped. The plot to the left of the two is also undeveloped.
As far as I know, there is no development plan from the municipality. Basically, anything can be built. No matter the form, roof, etc.
Of course, you are not allowed to build "anything" just like that. But naturally, you and your architect do have some freedom. The whole thing must then be approved by the responsible building authority.
In general, the construction must fit the "character of the immediate surroundings." This concerns the size, the use, as well as the construction type (detached or attached).
Hi
The issue with the setback areas then only refers to the height (length) of the house and not to the entire length of the plot, or was I misinformed?
So if I have a house length of 10 m, my parents would have to maintain this 2 m setback at exactly this height on their property, right?
That would most likely be their garden anyway, because their house would then, due to the staggered plots, stand further north (top of the plan).
As far as I know, what you say is correct. That it only applies to this house length. But as far as I know, the distance is more than 2 meters (at least 2.5 meters depending on the federal state). In other words, at least 5 meters must be kept from your boundary. Thus, your parents’ plot would be almost unbuildable. See sketch
Blue: House on your plot
Red: Setback areas
Yellow: Theoretically still possible development on the parents’ plot.
Hi
On the subject of "mutual party wall obligation":
Good that you brought up the topic.
If we have this mutual party wall obligation registered with the notary, are we then obliged to build exactly on the property boundary?
At least, that's how I understood it.
Oh yes, the plots have almost no slope. Only a little at the driveway (top of the plan)
To my knowledge: Yes, then a party wall obligation is registered for the area along the boundary where you plan the house. That means if your parents build later on their plot, they must build directly adjoining your house without any gap in that area. In the rest of the plot, to my knowledge, construction can/must be done with offset again, unless a mutual party wall obligation is registered for that area as well.
