The yellow text gives you eye cancer. Yes, that's also an option. The all-purpose room is a bit tight with 45m², I think. And the access to the pantry should rather be via the hallway, otherwise the kitchen becomes difficult to furnish. The shower toilet is hardly usable - too small and the interior walls are a bit thin. But otherwise...
True, the all-purpose room is a bit tight and could get cramped. You are also right about the pantry. The interior walls are drawn with 11.5.
Original. I thought the utility room was supposed to be at the bottom of the plan?! Shower toilet very tight, 2 toilets and 4 washbasins in one bathroom? Shower, tub, and toilet at RBM 3.85 is also very original. The bathroom reminds me of a 1930s laundry room with a sitting tub. The sketch doesn’t inspire enthusiasm...
If it doesn’t work out with the utility room, you have to take new paths.
You are right, the sketch doesn’t inspire enthusiasm.
The utility room is now as far away from the street as possible. With our drafts, you were already groaning when there was one more room in between. Definitely try furnishing living/dining/cooking ... those are dimensions where it always gets difficult with sensible furnishing. Guest WC quite far in the private area .. hmm. Where is the staircase supposed to be accessed from? It will probably have to be at least quarter-turn, so it needs more space to the right of the front door.
Sorry... You are the professionals, you automatically have high standards somehow. True, living, dining, and cooking could be difficult. The utility room also takes up space.
Surely it is well meant, but Dad’s talents lie (hopefully) elsewhere: sanitary fixtures, interior doors, windows – none of that looks like it should be built wisely. At least the suggestion of the bidet is sympathetic and worth considering.
I think he meant the basic arrangement of the rooms. My father is an engineer in retirement, he has designed a lot with ACAD but not houses.
