Draft single-family house with 3 children's rooms, basement, and boundary construction

Is the staircase planned on the left or the right?

The staircase itself should be a bit wider: 1 meter for the stairs plus 20 cm for the wall (structurally load-bearing is probably unavoidable, i.e. at least 17.5 plus plaster on both sides). But then the passage becomes quite narrow – better reduce the WC and the corner by about 20 cm downward.

I would give the bedroom/dressing area an extra exit and also add a sliding door to the dressing room itself so that after dressing you can go directly into the hallway without waking the one still sleeping with light and noise.

We found the idea much nicer that the staircase to the ground floor is on the left and you only actually look into the basement when you walk along the hallway on the right.

The stair width is 900 mm, wall at the stairs drawn with your dimensions (not exact mm).
Wider would certainly be good, but then it reduces our wardrobe and with 5 people we definitely need space here.
With the space conditions a 900 mm wide staircase is an acceptable compromise for us.

The only option I can think of to make the kids' rooms bigger is to box in the stairs. But unfortunately, this means losing daylight in the hallway:

Thanks for your suggestion, I already had this idea as well.
However, not much is gained.
On the contrary, you lose the light in the hallway, as you already pointed out, and I would like to give the kids all a room facing south. Mh...

How do you see the arrangement: main entrance, carport, garage?
Is everything too tight and the access to the house rather like a back entrance (especially if a car is under the carport) or is it okay?

I really like the ground floor, especially the kitchen is similar to what I have in mind

Does the upper floor extend over the kitchen area of the ground floor? Maybe it takes too much sun, right?

There are two things I don’t like about the upper floor:
- The pathways in the parent’s area, I would also prefer the door in the dressing area. Even though that naturally takes up space... difficult...
- The parent bathroom is really very small. If the pane is then also opaque, it will definitely be cramped and dark. And fire protection means no possibility to open the window, right? That reminds me of my first own apartment. And it was small

how wide should the kitchen be?

you have a drainage problem with your floor plan. The wastewater from the upper floor runs through the living/dining room.

Here is another suggestion:



The children's rooms are no longer in the south now, but I think that has become overrated anyway due to the heat...

Detailed dimensioning can be provided later if the representation using squares is insufficient.

Oh yes, I completely forgot this last night: Thanks for the scribble drawing, it's a relief amid all the "3D Maggi Fix for Instead Villa" that I often endure here otherwise!

The children's rooms are now no longer in the south

Unfortunately, there is a fire protection wall in the north, so normal windows are not permitted. You can tell that the OP has put a lot of thought into this, and I think it is almost optimally solved. I would probably make the children's bathroom smaller (only 1 washbasin or a long one with 2 taps) and add the gained width to the parents' bathroom. That is really too small. I would then give it an exit, unless you all get up at the same time now and in the future and go to bed at the same time. If the parents' bathroom is wider, I would opt for a window strip. That brings more light and allows a view of the sky. Having the garage and carport in the south is unusual, but creating a separate garden space in the east for breakfast has charm. Overall, I think it is well solved. It will surely be great!
