I searched through my old plans and found one that might also fit. The fireplace can be omitted here or installed at the top of the plan opposite the stairs between dining/living. It would then be more of an outdoor fireplace. One could also consider swapping kitchen/living to further open up the window front facing south. The question also is how far the attic should still be used. Because with the straight staircase as a continuation it won’t work well. Then the pull-down attic ladder would have to be used again.
WOW thank you very much for your effort! Even if it doesn’t quite fit for us. The living room is too separated; we want to keep the living, dining, and kitchen areas together since we also use these rooms the most now. Otherwise, there is still a room missing for the office.
Very old program: Architect 3D Maybe rather like this?:
Thank you very much for your suggestion. After much back and forth, we have come to the conclusion that building the utility room is not proportional to the cost of the lines. Depending on what the gas connection will cost, we might possibly do without it and install a heat pump. Otherwise, there is still electricity, wastewater (which has to go around the house anyway because of the rain gutters), and fiber optic. I think we can definitely conclude the orientation of the house with that. I will make the floor plans right away and upload them here. Looking forward to your feedback. Best regards
