Floor plan optimization city villa + fill consideration

Do you think a hallway about 1.6m wide is enough if you no longer put furniture in the hallway?

For me, this hallway width was a whole hundredweight fatter than now including a shoe cabinet, and I even consider you quite petite.

Some architects don't care at all and simply take whatever the layman accuses them of...

better let a professional plan the window size, otherwise your house will look like it was drawn by a 3-year-old

A draftsman learns for threeand a half years, but without this topic being on the curriculum.

You usually also get a 3D model where you can see everything exactly

even the smallest construction companies we have have a program with a 3D view! Such a thing nowadays is no longer a luxury but standard

Oh, not only normal case, but also standard right away. Respect. Where do you live - in Grünwald, Berg am Leim, Starnberg, Herrsching? - or in Hamburg-Schnöseldorf?
In Meerbusch this is not standard, and also not in Hahnwald; likewise not in Kronberg, Homburg vdH, Ludwigsburg, Baden-Baden.

I think 3D models only exist with the very high-priced providers, Viebrockhaus etc.

Even Viebrockhaus or Büdenbender are still too low-priced for that, that only exists with the most select Dr. Dr. star architects.

I don't know your architect, but if I tell him to plan church windows and a bell tower, then he has to do it.

You can still get the church windows approved by a good lawyer in Pforzheim even in the 34 zone if necessary, but I see no chance for the bell tower regarding the exceptional permit.

See? If he had shown you the house in a 3D model, you would surely have had more input and probably decided differently.

He wouldn’t have: his question was about rafter replacements for roof windows; and he would have decided differently only if the 3D model had been detailed down to the ventilation and drain pipes. But these problem areas would also have been shown by 2D drawings if only they had been made.

I admit that I also had almost no plan when I decided to build a house, but I was very aware of what I want and need.

Now the readers are even more curious about your house than about mine.

For us, it was actually an architect from the BU who advised us for a few minutes. Of course, the drawings were made by the draughtsmen for him, from whom I also did not expect any improvements. But an architect is an architect, and even if he is employed at the BU and not freelance, I have a certain expectation there. I rather see the aimlessness or ignorance of the clients, which nullifies a possible better work of the architect. Although I also did not have the feeling with ours that he wanted to enthusiastically develop a great floor plan with us from scratch – maybe he was already too jaded by the mass of budget builders who just want a typical house without architectural ambition.

I don't understand why 3D views are dismissed as so abnormal.
There are even members here in the forum who can whip that up effortlessly. My BU didn't even take an hour for the first 2D and 3D draft.
Maybe we're talking past each other. Of course, I don't mean a 3D model made out of cardboard like in architect tendering, but a 3D computer model...

But an architect is an architect, and even if he is employed at the BU

If the client is a public health insurance patient (= only "pays" all-inclusive for the building application planning at the BU), the employed specialist only acts as a clerk "draftsman" and not as an intellectual "architect". What You pay for is what You get.

If the customer is a statutory health insurance patient (= in the BU only pays all-inclusive for the building application planning), the employed specialist only acts as a clerk "draftsperson" and not as an intellectual "architect". What You pay for is what You get.

Exactly. That’s how it is with us. I can’t change it anymore. But save what can be saved.
And I don’t have a sofa problem and no hallway problem.
The hallway is currently 1.8m and I just don’t want to unnecessarily allocate sqm to the hallway. Then I’d rather have my TV stand 20cm further away.

On the one hand, I can confirm that it is not a standard on the part of construction companies. On the other hand, I understand your opinion and share it. I would have expected that with today's "drawing software" a 3D view can be created automatically and that this should not be a problem. If even an open-source program like Sweethome3D manages that (admittedly by no means perfect), one would think that it is available at the push of a button in professional architecture programs. But maybe it is the case that the software manufacturers charge a lot for this additional feature and then construction companies might say, "No, I won't order it; if customers want something like that, they have to pay the architect extra" or something like that.
