This floor plan has already been optimized several times and we already like it quite a bit.
From the core planner
Nothing was copied here ... if anything, it was at most inspired by it but almost everything was somehow changed (proportions, rooms, facade, windows, etc.)
You don’t need to fool us – we do have eyes in our heads ... changing a few windows is not enough.

I have deliberately restrained myself with my comment, which unfortunately is also negative. Luckily has already written my words for me – I fully agree with him.
The exterior view, especially east and south, looks very bulky – no grace of a Bauhaus of today’s times.
Due to the small covered terrace as well as the upper balcony, it looks like a two-family house. The wide house/estate is practically squeezed onto a long, narrow plot.
It does not fit the plot. Even if Mr. Neighbor is building equally squeezed, simply: it is not nice and not fitting!
I wonder why one opens a (main) terrace as well as the living rooms towards the street when the rest of the property offers many possibilities, also regarding construction and privacy screening. Only the regulated distance of 3 meters was observed (more on that later). In this respect, from the living room you will only look onto a street or at best on a hedge, but that hedge already consumes one meter in width. From the garden you have: nothing!
Also, the access from the kitchen to the dining terrace (covered terrace) is way too long and goes through the lounge area. Then you need a butler with a walkie-talkie to serve the salad at the grill.
The use of the garden is also restricted due to the office extension, which apparently is also used or visited by people outside the family. The guest room on the ground floor drastically minimizes the view into the garden of the living area. You could basically do without 500 sqm.
That brings us to the subject of the roof terrace/balcony, which I also question: why a roof terrace that has no relation to the upper living area except for a narrow balcony door from the hallway? If at least there was a sauna in the bathroom above and access to it was created so that one could cool off or relax outside after a sauna session – then the roof terrace would not just seem to be added for the sake of having it? Also, it is far too dangerous for kids because it cannot be overlooked from the garden. The paths to the balcony/roof terrace are too long and cumbersome for hanging laundry. For relaxing or sitting? Who wants to sit up there closed off from the house? What is the garden for?
Regarding the setback distances at the house to the property boundary: as a layman I question whether a two-story building complies with the setback of 3 meters to the property line. Shouldn’t it be somewhat more, the higher the building?
Regarding the interior:
I am thinking about whether it is convoluted. And yes: you enter and somehow as a guest don’t know where to go.
I find the allocation guest/WC good, also that the rooms are not in the entrance area, but they have taken up the space that was actually intended for the open plan (kitchen/dining/living).
The staircase is a dream without children, I wouldn’t want to see my child on it until age 10.
I find the spaciousness okay, the living area is not a huge hall but rather of a modest size.
To reduce the bulkiness of the house and also to comply with the setback on the right side, I would shift the upper complex to the left so that the bedrooms are more in the southwest, and on the right a single-story flat building above the living area.
But: I would choose a different house (or have one designed if you like) where kitchen, dining and living face the garden and the terrace is protected in the southwest.
Edit: with 3 children I see the cloakroom stored under the stairs more, even if as a parent you don’t like it. Eventually, the children will do it, and themselves too, when jackets need to be quickly put away to be needed again shortly after. Thus, the dining area will not have a nice view into the hallway. It could look uninviting.
