Just briefly:
You now have nice large rooms upstairs, but storage rooms are still missing.
If you collect jackets and shoes in the hallway and under the stairs, there is still only the utility room left, which is much too small including technical gadgets.
Possibly check if the upper floor can be designed differently so that another storage room can fit there.
Possibly near rooms 2 and 3, where room 2 has its niche.
The fireplace through the cabinet in room 3 is funny.
By the way, with this staircase, the chimney can be nicely integrated into the corner of the stairs.
I stand by it: With 5 people and so few storage rooms, you need a U-shaped kitchen so you can store things there.
Disadvantage: More kitchen furniture costs more money, obviously.
