What disadvantages does cultivation at the terrace boundary have for us?

There, contributed it again as a report of experience, which I also feel. How far do the properties extend further downstream according to the plan?

The property is unequally long on both sides. On one side it is about 5 meters and on the other side (next to the neighbor) about 9 meters long.

Ideally, you build exactly the same but mirrored. Maybe that saves you costs in planning and then you wouldn’t care. Otherwise: What would be important to me in your place is, what will be on the extension? If a balcony is going there, I would refuse. Otherwise, I don’t find it so dramatic in this case – [Sichtschutz] will come anyway.

In my opinion, he is not allowed to build a balcony. It is also not intended according to the view.

In my opinion, the extension is only about 1.0 m higher than a partition wall, which makes little difference in terms of potential shading.

I would first have the contractor plan my half and then assess whether it suits me. I hope the architect puts in as much effort for you as he did for the neighbor. So far, only the stairs are visible, which are well placed.

Don’t you have a plan of the entire property of the two semi-detached houses?

The floor plan of the neighbor’s attic is also quite important. Show that as well.

Unfortunately, the OP is very secretive about it, as I already noted on Saturday at 01:41:
