Floor plan optimization (expansion, adding floors)

Hello dear community!

I am new here, so please forgive me if I haven’t included all the information right away. I can gladly provide more if needed.

We are in the process of expanding the upper floor and also extending it a little. There would also be a separate entrance. In other words, parents live downstairs and we with our family upstairs.

I have somewhat followed the guideline. I hope the information is sufficient; otherwise, as mentioned, I can gladly provide more.

The basement already exists.

What is the most important/basic question about the floor plan summarized in 130 characters?

I am basically satisfied with the first plan. I would like to get a few tips from you. I have summarized some points that are important to me here.

[*]I would like the kitchen and living room to be separated by a fireplace and not to enter the living room directly from the cloakroom. I would like the living room to be a retreat room and not a pass-through room. But I don’t know how much possibility there is here since the fireplace connection is already given. With the slanted wall, we could extend further out to gain more space.
[*]Do you see a problem if you always have to walk through the living rooms to get to the children’s rooms? Teenage years?
[*]The terrace in the plan is much too small. At least 30 sqm must be available. SE or SW?
[*]The dressing room will be separated from the bedroom since we both work shifts and don’t want to disturb each other while dressing.

Upper floor
Grey walls are existing structure
East side and south side are municipal streets

I am aware that the possibilities are relatively limited due to the existing structure. Nevertheless, I look forward to your suggestions and tips.

Best regards

Do you see a problem if you always have to walk through the living rooms to get to the children's rooms? Teenage years?

At first glance: I don't see a problem as long as you refrain from holding secret baking parties, since I see the kitchen as a central unit.
I would have a problem with the location, layout, and size of the quiet area: a small sofa directly in the hallway... is basically incomprehensible to me. The dining area also basically has no space. The kitchen is planned much too large. I also consider the island far too oversized for the area.

-> More space for chilling together (at least 4 seats),
Less kitchen. Give up the children's bathroom, thus gaining space where it is needed -> all-purpose room.
I would swap the kitchen and sofa corner and reduce one children's room in favor of the all-purpose room.

Thank you for your response.

Yes, I completely agree with you. I would also make the children's room a little smaller. Maybe the room (living room/kitchen) can be extended a bit to gain a few more square meters.

I also think swapping the living room and kitchen is a good idea – I just had some concerns about the southeast orientation. But I think I am overthinking it.

Separate bathrooms for children and parents are very important to me.

I can only agree with YPG on all points. The apartment is too small for a children's bathroom.

I don’t understand anything (that I can imagine as feasible). The plan says: demolition of most of the existing wall layouts, as if the house is essentially being "blown up larger" and rebuilt; load-bearing walls are also being removed, and a new load-bearing wall is placed where there is currently no visible load-bearing wall beneath. A part of an existing wall line juts out diagonally. The staircase is being built in front of the previous floor plan; an office branches directly off the staircase, and one could only get from there to the WC in the apartment through the staircase corridor; the roof structure is almost completely reinvented as well. A fake? – can someone not wait for the beginning of April? ? ? ? ?

I only thought about it because of the southeast orientation.

We don't have to worry about it without an orientation indication.
