Idea generation - Orientation of the house

One more brief remark on the following statement:

Then from the terrace (in the southwest) we look directly at the neighbor’s garage to the south.

That should actually not be a big problem. I would simply plant something in front of it that later sufficiently covers the garage wall, so you just look at greenery, especially since the neighbor has already planted cypresses along the boundary anyway. However, I would have a look at the distance of the already planted cypresses from the property boundary; there are rules about how tall they are allowed to grow. As far as I know, that depends on the distance of the plants to the boundary. And if the allowed height is eventually exceeded and you do nothing, you can’t object to it later (I think you have 5 years here) and have to live with the shade. My neighbor has a similar problem with another neighbor (house is rented out, garden hardly maintained) and apparently can no longer do anything about it.
In the further neighborhood, there is a property near us with at least 5-6 meter tall thuja trees close to the boundary. The affected neighbor probably doesn’t mind much because these stand rather in the north, but with you it would be the south, so the main sunny side.

PS: Where in the Osnabrück region do you have your property in sight?

And if the allowed height is eventually exceeded and nothing is done about it, you can no longer object later (I mean you have 5 years with us) and have to live with the shadow cast

Hello Frank,
Thanks for the tip, I hadn’t thought of that yet :-)

PS: The property is in Bramsche - Hemke III

The affected neighbors there might be disturbed little by it, because they are rather located in the north, but for you it would be the south, so the main sunny side.

...especially in the south within acceptance, as the sun is highest there and above the hedge planting. In this case, the hedge would rather be in the shadow of the house ;)

there are rules about how tall these are allowed to be at most. As far as I know, this depends on the distance of the plants to the boundary.

Lower Saxony Neighbor Law §27 Enclosure Act, not to be confused with §50 (boundary distances for individual planting) In this case, a communal planting in the middle of the property boundary would be regulated. I would just leave laws aside in this case ;)

Heights of enclosures are usually regulated in the development plan.

I'm not surprised at all that there is a law for something like this in Germany. :-) The development plan, however, says nothing about the enclosure. But I am quite relaxed about this. I think you can certainly discuss it with the neighbors to ensure that the planting is okay for both sides.

Hopefully one can come to an agreement with the neighbor, I also assume that. However, one unfortunately always has to know the legal situation as well.
