Floor plan of a single-family house for 4 people with problems on the ground floor

The technical room must be constructed within the thermal envelope.

I also think that I gave the architect too little freedom.

True. I was also surprised where the architect's touch is visible in the design. On the ground floor, the rooms are simply lined up next to each other. A guest toilet can of course be placed at the front, even with a window and cloakroom area in front of it, because the windows just need to be split in two, also in the kitchen... 200 sqm with a toilet without a window, that's quite a statement ;) Aside from the fact that a lot is amiss there, I didn’t understand your issue with the dining area being too large. The dining area is practically the central place of a household, especially with children... But here I hardly see any planned dining and living area. 2.55 meters is far too little. For a 2-meter-long table, there should be 4 meters in length... then additionally check the accessibility of the terrace doors and create space. The freezer belongs inside the thermal envelope, wardrobe cabinets are very important... 2 meters for 4 people fills up very quickly. Quite spontaneously, I would suggest it like this, without changing too much

And so the upper floor. Children's room facing south and into the light, bedroom with north-facing window. Children live in the room, sleep, work, play, hopefully still meet friends. In the bedroom, one only sleeps.

unfortunately the office no longer has a window. The garage possibly moved a bit to the back. The staircase would also please me better the other way around. Then you don’t run into the wall. From the living room directly to the staircase.

Oh yes.. overlooked in all the hurry. Turning the staircase also makes sense.

Thank you

Is there already a new draft?
