Beautiful big house, but there are some things I don’t like so much either. I don’t like the living room at all. The recess to the upper room makes the space awkward and doesn’t bring much benefit. The doors behind the sofa take up a lot of space that is not usable. Additionally, you have the south window opposite the TV and the west window lets in side light. I currently have that as well and often have to darken the room to be able to see anything. If the living room is supposed to have that depth, then I would include the covered terrace area as well. This also makes the hallway straighter and the upper room larger.
A lot has already been said about the kitchen, so I will keep out of that. Regarding the storage room, I think it’s good. However, you’re missing a vestibule or wardrobe area. You enter a relatively long corridor and immediately left and right are doors. Otherwise, you have a spacious house, but when entering it feels very cramped.
I also don’t like the upper bathroom. It is very spacious, but everything is somewhat cramped: small shower, little space by the toilet, etc. It really looks like you planned the bathrooms around the changing tables :-) With so much space, I would treat myself to a nice big shower. If a sauna ever becomes an option for you, you should consider whether you really want to put it in the basement or if you have some space on the upper floor.
I also find the dormers in the children’s rooms very cramped (and I would reverse the window opening directions). If possible, make them a bit wider and put the wardrobes along the top of the plan.
