I have reconstructed it:


First, the car situation should be clarified. In and out must work.
Then the front door can be positioned sensibly. (That does not mean it is currently planned nonsensically).
Then the question remains whether a 70-year-old or a 50-year-old is planning here. The new 70 is the old 60... and I would then connect to where one might spend their retirement if in doubt: upstairs or downstairs and plan accordingly, if one even has the choice.
It may be different everywhere else, but here you wouldn’t sell this house to a family of four with two children's rooms of 9 and 10 sqm each (my walls are only 10 cm), but a kitchen of almost 20 sqm. Therefore, I would refrain from trying by hook or by crook to plan two equally sized children’s rooms.
An office could also be a desk by the window, with the printer in the utility room. The utility room is about 130 cm wide...
Better a multifunctional room than two holes.
Your design has 3 toilets for the supposed 2 people. I would also question that.
Honestly, it seems to me as if you are new to the forum and basically only have the big Pinterest wishes of pantry, showcase kitchen, master bathroom and straight staircase. I am a bit disappointed. But maybe I am also a little too strict with you, and it can't be done any other way. Or maybe you are just the clumsy one and have disguised yourself well. In any case, you are true to your nickname. You can do slope. I can’t.
At least I would try to position the staircase crosswise so that the whole width is available in the house and at the bottom you don’t run into a wall, but feel like you are going into the garden because a terrace door welcomes you there.
However, with this crosswise staircase, it is difficult to get to the attic. Maybe the attic should be held here as a reserve for sale, so leave it untouched for now and plan the living space for old age without these children’s room alternatives.
