Actually, I don't think the original idea is all that bad. But in the implementation... it reminds me of stories where people blindly followed the GPS (in this case the idea) and then ended up with the car in the sea or on the subway stairs.
For the next draft:
1. Rooms should function well in everyday life.
Examples here, where I suspect this does not apply:
Utility room huge, but almost only (very expensive) walking area.
Ratio of living rooms to utility rooms very expensive.
Entrance area will probably become annoying quickly in everyday life, because it is somehow only half implemented (not big enough for a functional entrance area).
Ground floor WC without window (do you really want that?!).
(I know the ground floor WC is often called guest WC. But if family life mostly takes place in the living room, it will be used often.)
Whether the segmented room (cooking, living, dining) works, I don’t know either. It seems very cramped to me.
2. Consider: What do we need?
Also: Keep costs in mind! The question is "need," not "want." First must-haves, then nice-to-haves.
3. Look at what the plot dictates (orientation, development plan, etc.).
Then create the best possible fusion from that.
Light and walking routes always belong here as well.
And above all: Functionality of the rooms! In particular, depending on the desired heating technology, the utility room is likely to be so non-functional in the end that the (also large) storage room would become the utility room.
