I hope this is somewhat understandable.
Not for me. But I think it matters less whether you CANNOT move or shift the house here, because the garage offers NO possibilities.
Since the garage with passage can only be implemented as currently planned, the utility room and main entrance must also be on the east side. As soon as you change the dimensions, you run into problems with the room and corridor widths on the ground floor.
What confuses me here is the "only this way" and the "must". The building envelope was not known either, or did I overlook it?
We would like a bit more space between the right wall (towards SK) and the peninsula and shorten the peninsula a little. If necessary, the kitchen can be extended westwards on the north side. We would then not position the dining area in the northwest corner, but rather towards the center (entrance
I would definitely decide beforehand where the dining area will go. There should be about one meter between countertops. But it also depends on whether, for example, you block yourself with a U-shape dead end, which is present here and leads to the pantry. What should go into the pantry? To me, it looks like there is space for 2 tall cabinets there, but it uses up the space for 3 tall cabinets. If you now leave the dining area at 2.70, it could get tight. For example, we have 90 cm on one side for the chairs. If my husband sits there for a chat or coffee in between or while playing (so not while eating), then no one can get through anymore. So if you have a casual game night or friends’ evening, you have to keep moving if you want to get drinks. Therefore, be sure to plan the kitchen optimally now, as advised, and not with the placeholder measurements from the architect; otherwise, you will have neither fish nor fowl. Then all possibilities could be off. Personally, I would have no objection to docking a dining table to the island, but it should really be planned with the option to extend or rotate the table during family celebrations. In this case, I do not even see the possibility to open the patio doors... Definitely redraw the plan on graph paper and place templates of your furniture on it. Where will the dishes go, the sideboard with the place mats, the sofa and the TV. If you put the sofa against the wall
but rather towards the center (entrance to the living area). In the northwest corner, at least a seating area for 2–3 people (bar stools or similar) could then be created.
If you implement that, then you would have wasted 2.70 m for bar stools, while the centrally positioned dining table already collides with the TV seating area or the stove is in the way and demands one seat at the dining table. Why was the garage enlarged now? What was the concern? Why is there a huge walk-in closet if it is not even requested? I find the previous upper floor plan much better, even if space next to the stairs is "wasted," the children’s rooms are the same size, the 9 meters are well distributed across two rooms, the walk-in closet could be used as a storage room or a utility room for laundry, and the bathroom planned differently. Regarding orientation: since you plan to shade part of it anyway, I would always orient the open-plan living area to the south. Especially from October to Easter, you benefit from the orientation inside the house; as for the terrace, whether south or west, I consider it negligible given your optimal plot location, as you can arrange several terraces. Over the years, you develop your own preferences that you can’t really influence now.
