My fingers are also itching to come up with a counterproposal that gives the open space including the kitchen (whether separated or not) a bit more of a positive spatial feeling. Because whether the sofa is placed in front of a closed wall (cave effect), but the feeling through window positions and partition walls as well as sideboards, which one would bump into, as well as a kitchen that relates more to the garage than to the living area, rather creates an uncomfortable room climate here. A staircase here with its storage room as well as the idea of walking through all the rooms certainly doesn't make it any better. The window positions additionally make the rooms longer and narrow good furnishing options. I see here at least a south-facing window in the living room about 2 meters wide, a closed wall to the south in the dining area, and instead an opening of the dining area to the west garden. And this way, the rooms gain more spaciousness. The current state makes the dining area feel tubular and has no possibilities to place sideboards without stumbling over them. One-meter-wide terrace doors also don't exactly let the gaze wander into the garden but rather restrict it. Maybe I will come around to drawing tonight, but I bet that I will come up with a completely different floor plan if the house gets a passage to the garage utility room.
