Kitchen area, transition to dining and access to the terrace have clearly lost with the latest ground floor version. The kitchen area is too wide for practically a 2-line kitchen with a small peninsula. The passages towards the terrace are inconvenient when maneuvering around the table.
Regarding the parents' area ... the closet area drawn on the left side of the plan doesn’t look great due to the corner window .. in general, I find the intended closet areas a bit like “we are creating a labyrinth” and the then open area to the right at head height from the bed I also find unsuccessful.
I can fully understand your wife regarding the floor-to-ceiling windows. And lowering to 75 cm is also worth reconsidering. I also find the distance between the window / intended closet wall in children's rooms 2 and 3 unfavorable. I also find the bathroom planning on the children's floor unfortunate ... the shower in the shell construction is not even 90 cm wide. Exit of the shower facing the washing machine? Washing machine/dryer stacked without laundry folding area is also not ideal.
So, and now enough complaining . By the way, I really like the spacious staircase . Basically, I would try to get a bit more southern light into the living area, especially the kitchen/dining area.
Where should things like bicycles, lawnmower, garden furniture, etc. be stored?
I would also be interested in a plan of the plot with the intended house positioning and possibly building boundaries. It definitely seems completely flat.
