Floor plan - house planning carried out by a civil engineer

.. that's how I just tried it with the house designer .. like type 145 ... however, it immediately becomes apparent that type P 145 is at least 150 cm wider.

It won't get much easier with other staircase shapes either.

... I would also consult the architect again. However, not with the requirement to change the staircase shape, but to eliminate the following points as much as possible (referring to your original plan):

[*]Parents' bed position .. 320 cm is too little width for a bed with a mattress size of 180x200. That’s only about 60 cm to the right and left of the bed
[*]Children’s rooms should be bigger considering that 140 cm beds should also fit for adolescence and that placed wardrobes can be used and accessed ;)
[*]Guest bathroom with 176 cm is too narrow, at least for the intended furnishings .. wider or another furnishing idea. The shower there should also be 90x90.
[*]Dining area in addition to the kitchen is too tight, no passages
[*]Southeast window
[*]Possibly an additional northwest window in the kitchen
[*]Technical area in the utility room .. is that really sufficient? Is technology and opposite shelves possible in the 223 cm wide section?

[*]Niche in the utility room facing the kitchen is actually unnecessary and takes away good placement options from the kitchen
[*]Also consider for the utility room whether the entrance from the garage should not be more towards the top of the plan. When will this entrance be used? And by whom? How should bicycles be stored? Car in the garage and then unpacking the trunk .. that will make more sense towards the top of the plan, so you don’t have to carry everything past the car (there could also be bikes etc. in the garage ;) )

Oh dear oh dear....
Your priority order:
Straight staircase > cars > dressing room > children....
The straight staircase is great, but simply not possible given the house size and the number of rooms needed. I find a children's room under 14m² borderline. A dressing room is a fashion trend. Just compare the time spent in the dressing room to the time children (especially aged between 10 - 18) spend in their rooms. Who is the large hallway upstairs supposed to benefit? Maybe smaller children, but from puberty onwards no one will "play" there anymore.
Imagine a family gathering on the ground floor... it's all way too cramped and convoluted.
Apart from the external dimensions, not much fits in there.... sorry, that's my opinion.

Stairs straight ahead > cars > dressing room > children....

Where did the OP write that? He just wants three children's rooms, a study, a double garage (in my opinion all legitimate). He wants to spend 310,000 euros on that. The latter could be the limiting factor. Does anyone know floor plans with 6 rooms (each large enough for all wishes), which add up to about 160 m² of living space, so that the budget is not exceeded? @ Is it actually possible to build over the garage? Then the upper floor might be considerably larger, all solid construction, also not cheap, but maybe doable? [B]

thanks for the support. Considering 3 children's rooms each with 14-16m² would be a bit exaggerated with the "tight" budget, wouldn't it? The garage is not buildable over. I also don't want to get any bigger. That would just cost more again.

I will probably try out a few more variants. Maybe a good solution will still be found.

... I agree. I think you should continue with the approach from and the architect questionnaire from . The children's rooms have enough free space in this version. If there is a third child, then the slightly larger room will have to wait for the departure of child number one ;) ;).

In the meantime, I have also experimented with other stair designs. If you don’t want a lot of angled walls, etc., the desired room layout on the upper floor simply doesn’t get any easier, at least not for a layperson ;) ... Especially if you also want to implement the very understandable requirement, "staircase not in the entrance area." For example, I find that more important than squeezing out half a square meter for the children's rooms. One must not forget that there are no sloping ceilings on the upper floor either, meaning the room sizes are fully available.

I'll put it this way, we currently have two children. However, we do wish for two more in a few years. And we have a house with two children's rooms on the upper floor and a playroom on the ground floor. So far, both boys sleep in one room and that will remain the case for a while. When they reach puberty and each wants their own room, that will also be possible. Then the two little ones will have to share a room... I don't see any problem with that at all. I always really liked sharing a room with my sister. And the boys have also been very comfortable so far. It has been more important to me to have two large children's rooms (each nearly 20sqm with sloped ceilings, 17sqm living space) than three tiny rooms... No idea, it's probably all a matter of perspective... And whether more children will actually come later is still another question. ;)
