I need support with the replanning of a house.

Hello dear forum community,
After a long search, we have found a suitable house that meets most of our wishes, including seclusion, large plot, close to nature, around 200sqm of living space, an outbuilding that can be used as a workshop, etc.
The house is a two-story, solidly built house, fully basemented with an unfinished attic. The living space of the two floors is about 200sqm.
The balcony and terrace face south, offering a breathtaking wide view, as the house is situated on the lower slope of an approximately 100-meter-high mountain.
The house was built in the early 80s and has not been renovated since, so the flooring, bathrooms, etc., are correspondingly outdated.
The layout of the rooms is also not yet optimal for us.
The house is meant to accommodate mom and dad with two small children and two dogs.
Our dream would be for one floor to have the kitchen, dining room, living room, and a small bathroom, and the other floor to have two children's rooms, parents’ bedroom (ideally also a dressing room), playroom, and a larger bathroom.
With this dream in mind (and a house planning software), we began to change the rooms. The goal was to remove or move as few walls as possible.
We are very satisfied with the ground floor; the kitchen is now open to the dining room, the dining room and living room are connected by a large wall opening, and the dreamlike view can be enjoyed from both the dining room and the living room. From the living room, there is also access to the terrace.

We are not yet satisfied with the upper floor. The two children's rooms (south side of the house) are different sizes (a minor problem). We found no possibility to plan a dressing room adjacent to the parents’ bedroom. The former living room is now a playroom, but the tiled stove in there is almost wasted. The bathroom is on the opposite side of the house from the bedrooms.

Since I tend to be one of the less creative people, I would now like to ask the forum for alternative suggestions and ideas.

Unfortunately, the room labels are written very small, and I cannot change this.
The two plans with the parquet floor show the current room layout, the two plans with the light wooden floors show the latest version of our planning.

Thank you very much in advance and best regards

I just saw that the plans are very small. Here again as an attachment.

Get yourself an architect.

I would quite spontaneously put the dressing room in the space behind the headboard. Just need to put a wall in there, that's okay. And then with a glass door because of the light coming in, why not? Regarding the walls, I would first clarify which ones are load-bearing before doing all the planning. You can make openings in load-bearing walls, but that's insanely expensive. Unfortunately, we have 3 doorways or passages between columns with concrete lintels above in the basement, and I once asked how much it would cost to shorten these lintels by about 10 cm at the bottom, which shouldn't be a problem since they are 40 cm high, totally exaggerated... and the cost estimate was around 1200 euros for the 3 passages... we had to sleep on it again, the passages are still unchanged.

Somehow the measurements also don’t match the furniture. So if I assume a 2 m long bed downstairs, then the upper floor would be 13x10 m with 5 cm thick walls? The dining table downstairs is as deep as the kitchen furniture, so 60 cm? I would really take the correct measurements there, especially draw the walls properly. then the whole thing looks different.

Do you know which walls are load-bearing and which are not? Do you know where the [Leitungen] are? Do you know what kind of [Leitungen] there are?
