I also looked for the option for grandma, but only found many oversized placeholder rooms in the basement. Or is the bedroom with bathroom for grandma on the left side of the plan? I would plan the center of the house, i.e. the entrance area, to be more homely. After all, you want to live in the rooms and not have to take athletic routes every day. Halve the dressing room on the upper floor and reconsider the dormers including the living spaces in the attic for the children. And if living space is going to be created in the basement anyway, consider a stylish light well on the side, which allows good use of the living space in the basement. That way, you can reduce about 30-40 sqm per floor. And even with the mentioned reductions, it will surely become a wonderful impressive house.
