Is the floor plan okay like this? Your opinion

We also have 9.63m in length for dining and living.
The living room gets 4.70m so to speak. The door is here as well. The dining room gets 3.60m. The second door to the kitchen/living/dining area is located in the kitchen.
So between the dining room and living room there are about 1.40m left over for a narrow room divider shelf at the end of the stairs. This is therefore the ideal central place for phone, laptop, cell phone charging station, mail, etc., and opposite will be the wood stove.
Space between living and dining is always useful, I think.
1. for extending the dining table during celebrations
2. for children to play and
3. as a fireplace corner possibly with armchair, shelf, etc.

It may not be absolutely necessary, but if you have the space, there are many ways to use it. :)

I really like your floor plan in terms of the layout, although I find 9.5m a bit too long for the living and dining room.

How do you come up with 9.5m? Those are the outer walls. Inside, it's only 8.90 and I think that's a good length. In our house, we will only have 8.30m and I already find that tight, especially when you have a table that extends to 3 meters long and people need to sit at it. Now we have planned something in the width in the dining area so that our living room is now L-shaped and we have space for this table.

One negative thing I did notice that would bother me about the floor plan (if you look, you’ll find ;-) ). If you want to get to the terrace, you always have to walk around the table or the sofa. We solved our floor plan so that we can get to the terrace either in front of or next to the table, so the table is never in the way. This was especially important to us with the kids, who are constantly running in and out. Maybe you could put a single door between the two large terrace doors, just to be able to get in and out comfortably without having to walk all the way through the living room when you come from the hallway.

So,

now I have re-uploaded the latest floor plan. At first glance, no major changes but the house has become half a meter longer.

The fireplace has been relocated.

The kitchen has been redesigned, probably without the counter. This should leave enough space to access the terrace.

The bathroom on the upper floor is to be planned differently. Probably with a T-layout.

Are there any further opinions on our planned floor plan??

Thank you very much

I think the floor plan is great. The only thing I would do is mirror the staircase from the entrance. Then you could make the wall at the front door slanted along the staircase, and that would open up the hallway a bit more.
