Floor plan design single-family house approx. 170 m² + attic as a modern clinker house

The dining table is usually the best part of the open-plan living area to enter it. [...]

So you wouldn't have a problem with that or am I misunderstanding you?

Regarding the attic, I think that could be improved with a skylight over the staircase so you don't have to crawl.

What do you mean by tip?

That means you wouldn't have a problem with that or am I misunderstanding you?

If the table is not placed crosswise in front of the door, no. But if I trip over it because I want to go to the chill room, of course yes. By "Spitze" I meant the attic, wrong choice of words, sorry.

Well, the table is placed crosswise in front of the door in this case...

We have only roughly sketched the DG so far. To the west a children's room, to the east a study, in between a small storage/technical room with the [Kontrollierte-Wohnraumlüftung].

I would personally never push the dining table against the island - unless you really have space problems! Limited accessibility of the island (drawers, etc.) combined with one less seat on the front side is not a good deal, but at best a compromise due to lack of space.

I would rather see it that the position allows me a table that can be extended longer. You are right about the drawers if the space is needed. Ultimately, what bothers me is the thought of walking routes, that you always have to walk around the table. But maybe that is just overthinking... This would determine whether the sliding door can be opened on the left or right. Of course, this also influences how you can/want to arrange your seating area on the terrace.

I don't see a problem with the pathways here. The important thing for them is rather that they are there at all and not blocked. Personally, I wouldn't dock the dining table unless it offers significant space advantages. You lose the workspace on the other side of the island. Ok, others swear by it, that you basically sit next to the cook and Mom can fill the breakfast plates directly from the front. It's all a matter of taste, I think.
