Basically the entire layout of the ground floor and upper floor. I am referring to the linked floor plan in your first post in this thread.
Putting aside what is current or not, and I can understand why you want to tear down and rebuild on the basement, but why like this. By "like this" I mean the usual open-plan room, a rectangle, kitchen/table/couch in a row as it is done in every second house. In the other f...um, I can’t write more or I’ll get a warning, someone is currently struggling exactly with that, to plan a sensible kitchen.
If I take the existing plan, it offers better usable rooms, assuming it will be a household of 5 people. If I just take the room dimensions of the plan, extend the bay window on the left side as a rectangle, only on the ground floor (regardless of whether feasible or not).

According to the plan, the existing kitchen room is 240 cm wide, ideal for a two-row kitchen.

You would have on the left side, in the east, a very large panoramic window with a bench in front across the entire width, with the dining table in front of it. In the kitchen also a wider window, also because of the view.

The kitchen then goes around the corner on both sides, right side a counter for what you need for breakfast, left side storage, low, medium-high or tall cabinets, whatever you need.
Terrace door as existing, possibly wider, the other windows as existing.
Although not the topic of this thread, there is no proper cloakroom for 5 people, shoes, bags, backpacks, buggies all lie around on the floor. But that has probably already been discussed. My daughter had 250m2 in the old house, everything great, only there was no proper cloakroom. Chaos at the house entrance.
What is the latest status for the upper floor?
The existing floor plan simply offers more options, you can spread out, the five of you are not always sitting on top of each other, don’t hear the kitchen clatter, screaming children, toys scattered on the floor. Kitchens with stone countertops are very loud, you have to get used to that first. I don’t want to see the kitchen chaos from the couch every day. We have about 70m2 of open-plan room, about like in your new plan, also 13 m, but the room is still not rectangular and divided into areas by 2 partial walls. I can watch a movie in the front, husband at the other end watches the Tour de France. There are no doors.
I would also think very carefully about whether a wood stove, in any form, still makes sense today. I think you get more from it for the transitional seasons if you install an aircon (inverter, split system) with reverse cycle for the open-plan room. Then you also have something for the hot days. The units consume relatively little electricity, require no work and make no mess. We replaced our 20-year-old one and could hardly believe how much better and cheaper the new one is (Mitsubishi Heavy Industries).
Regarding kitchen planning, in the so-called specialized forum, you can plan it better because, as here in the floor plan planning, there is a checklist. Without that, it’s only half the job, because you know too little.
