Floor plan of city villa with a request for improvement suggestions

Do I understand correctly that your stairs to the upper floor start in the living room? That means your children have to pass by you every time - with friends, etc. - when they want to go upstairs. Later, in their teenage years, a friend or girlfriend sneaks quietly through the living room? That wouldn’t be for me...

- Bedroom far away from the bathroom

Because this statement comes up again and again, a silly question: Is it not irrelevant whether the elderly have to take the "long" way or the kids? Theoretically, the kids should spend much more time in their children's room than we adults spend in the bedroom. Accordingly, the kids take the path much more often. It may be that in 20 years I will have to get up at night now and then and think differently, but by then maybe the kids have already moved out and the room layout will be completely different.

Mind you, we are talking about a maximum of 5m and not a marathon.

I might possibly turn the small children's room in the middle into the bathroom. Then it would be nicely central and everyone would have roughly the same distance. The drainage could then be routed through the office. A bit more complex, but not impossible.

The higher the drop height, the more light - quite simple. You did not address the fundamental problem with the darkroom on the upper floor. What is the wall construction of the interior walls? The floor height is 2.70, the clear height 2.45 - 20 cm floor slab and 5 cm floor construction on the upper floor - or am I interpreting that incorrectly?

I would have the architect draw it again, this time from the front, with the specifications you now want to take into account.

So currently the floor height on the upper floor is as you wrote 2.70 m - 20 cm for the ceiling - 5 cm for the floor (currently no underfloor heating planned on the upper floor) - The windows are 1.60 m high and 80 cm wide each. Sure, it is on the north and east corner, but so far we have assumed that this is sufficient (1.60 * 1.60). The only alternative I currently see for more brightness is to enlarge the window on the east side (so on the plan above) by 80 cm, then do the same in the ground floor, so that it looks uniform.

We have discussed the floor structure once and it does not cost much more. Is the difference of one row of bricks that significant? Can you feel those approx. 25 cm? Would you then make the windows higher?
Does anyone have higher ceilings and is it worth it?

I still have to inquire about the wall construction of the interior walls. We have a follow-up appointment tomorrow.

Thank you
