From my point of view, the house should be positioned as far east and north as possible: This would provide the starting point. Seating area in the south (thus there is also the evening sun) – therefore the last design is by far the best so far. Additionally, my experience shows that 2 seating areas (except in special situations) are rarely really used (just like balconies on the upper floor if there is a terrace on the ground floor). One seating area – but in the right place (here: south) – is sufficient. Regarding the rooms: I also find the bathroom on the ground floor too large. And on the upper floor, a "children’s bathroom" would certainly make sense. Guest/office room: Does it have to be that big? And I would miss a pantry: I would put it between the kitchen and the living room, and in exchange for that, I would do without the cross row of the kitchen as well as the French doors into the living room: With such a measure, you can do without part of the (expensive) kitchen furniture and would have a great (small!) storage room. The wide corridor between living room/entrance/dining area certainly adds something visually, but in terms of utility rather little. I’m keeping my fingers crossed for you: You will undoubtedly manage to get it according to your needs!
