Alright, that I can remember a little bit. It’s really inconvenient to request the deletion of threads and then not read the posts :(
My comments:
Site plan is missing.
Hmm ... I’ll start with the home office .. 200 cm wide, so my decent desk is 240x80 cm, if I place it in the office as you drew it, then there are only 120 cm left to the wall behind the back and shelves will probably need to go there .. I don’t call that a proper workspace.
Then the room that is supposed to become the parents’ bedroom on the ground floor later, furnish it properly (I also think you can somehow switch from symbols to actual drawings of the furnishings in Sweet Home). By the way, keyword here is door position because of a proper wardrobe.
Ground floor .. top of the plan, the plot should be such that you can put a terrace there, how that could look like, but sadly the site plan is missing. Double garage on the right side in the rather southern part hopefully does not stand on the boundary, otherwise the roof terrace will be tight, because distance regulations apply there too. And the prefabricated garage must be designed for a roof terrace.
On the ground floor I am missing a storage space for vacuum cleaner, mop, etc.
Basement .. I find the basement bathroom poorly furnished, only 200 cm wide, it will get quite tight at the entrance. And the door from the parents’ bedroom to the bathroom can really be omitted.
Main entrance through the basement and then around the corner etc. to eventually get to the stairs going upstairs, I also find that not ideal.
