Floor Plan Critique: Single-Family House with 3 Children's Rooms

The problematic thing is that we cannot become wider

Building boundaries on the plan could have shown that.

I will provide those as soon as I have the revision from the architect.

That implied to me that the previous drawings were already architect’s work. I don’t believe that not only because of the amateurish dimensioning. To me, it doesn’t look like ArchiCAD or similar – although also not like the usual MaggiFix for Windows Klikibunti 3D one otherwise sees here. I suspect some semi-pro drawing tool for somewhat more demanding users, but not architects.

But your clothes increase over the years. You are allowed to clear out and throw away, but hardly anyone does.
And eventually sports and rehab clothes, carnival costumes (ok, those can go to the basement) and fluctuating clothing sizes come into play.
I don’t care

You are right. We regularly move summer/winter clothes to the basement and back up again or actually don’t have that much. I mainly have suits and shirts. What I have is currently enough for me and for my wife too. But I do wonder what it would look like if even more storage space should be created.
Thanks for your input and food for thought!

Building boundaries on the plan could have shown that.

I cut those off. That was my mistake as a layperson. The boundaries are 3m on the side of the garage, 4m on the east side (kitchen), and 3m towards the street.

This is the preliminary study plan we developed with the architect. If you judge his professionalism solely based on the tool, then I’ll just pass that on to him. I’m talking to him on the phone tomorrow anyway. Then I’ll ask him what the tool he used is called.

In case you’re looking for a suitable tool for laypeople: Floorplanner (.com) (probably broken up as Bodenplaner or just say it out loud). I experimented with it for a while. It worked pretty well, except I couldn’t represent the roof. But 3D representations worked very well.

If you determine that he is not working professionally only based on the tool,

... then you have misunderstood me. I see (also here) so many drawings that although I do not know or even recognize all planning programs, I still can tell whether I see them often or rarely. I rather judge the (questionable) professionalism based on which details are mentioned and last but not least which ones are given dimension lines.

If you are looking for an appealing tool for laymen: flaoplaner. I experimented with it for a while. That went quite well; only the roof I could not represent. But 3D representations worked very well for that.

Thanks, I will gladly take a look at it occasionally. I myself prefer the analog tool "paper and pencil"—if I ever switch from the abstract to the pictorial level at all. A layman’s tool would always have its value for me strongly depending on how widespread it is here in the community. I do occasionally dream of one that’s good, also gaining relevant distribution. However, for me it would have to be one from which I can export arbitrarily in file format (since screenshots can hardly be further edited by others, at least not better than scans of hand drawings).

and I therefore shower in the bathtub,

Me too - the tub was important to us... and two showers for 2 people is one too many

I somehow can't manage that. When I turn and slide there I either have a tiny office or a hose.
Maybe I just don't understand your idea correctly.

Three meters office width... but it results in a stupid cut for the living room. Forget it.

The corridor needs more width in my opinion, otherwise you feel like you have to slam on the brakes at the staircase exit.

I have now noted this as an issue with the architect. However, I also think it is not really necessary. The bathroom door is usually open, and even if not, the door frame of at least 15 cm depth does not give the feeling of running into a wall. The only alternative would be a bend toward the bathroom, but that probably doesn’t make it significantly better. Everything else (moving the staircase) would be too much wasted space in my opinion for 10 cm more width.
