Floor plan of new single-family house: Are window/door/interior wall size/arrangement okay?

Hello,

we are currently planning our single-family house. The design was created and submitted by the architect according to our specifications; the municipality has also given approval regarding the exterior dimensions and the few deviations from the development plan. Now the design is with the district office and we are waiting for the final approval. As mentioned, the exterior dimensions are fixed, we can still optimize the interior, and I wanted to gather more opinions regarding windows (number, size) and general suggestions – is something too big/ too small? Are the distances okay? What should be considered? The floor plan is heavily based on my parents' semi-detached house, we are very satisfied with the layout, but maybe we don’t see further possibilities here because we have become “blind” to it…

I have already tried to plan the furniture on the ground and upper floors. "S" marks possible socket locations. Anyone who notices something is welcome to comment :)

The kitchen has not been planned yet...

Thanks in advance for all ideas!

Regards :)

What is the most important/basic question about the floor plan summarized in 130 characters?

Ideas for optimization suggestions regarding interior design/windows/doors, where something could still be changed. For example, I can’t quite fit the dining table at the moment… General comments regarding size – which rooms are too big/too small?

The draft was made and submitted by the architect according to our specifications; the municipality has also given the okay regarding the exterior dimensions and the few deviations from the development plan. Now the draft is at the district office, and we are waiting for the final approval.

Apart from shifting non-load-bearing walls or doors or windows, I see little left to "rescue" – but this is not essentially necessary. For the bathroom and kitchen, I still expect suggestions here; I have found no "errors."

hm, placing a double bed would be advantageous. But otherwise, nothing more can be done. Although a window can be moved by 20cm, it cannot be enlarged (Energieeinsparverordnung) or the facade design changed without an extended building application.

But otherwise, there is nothing more to do. You can shift a window by 20cm, but you cannot enlarge it (Energy Saving Ordinance) or change the facade design without an extended building application.

We were told that windows can be changed without an application as long as the specified efficiency does not change (which makes sense to me).

We were told that windows can be changed without any formalities as long as the specified efficiency does not change (which also makes sense to me)

Exactly, that's what I'm saying.
Enlarging a window, for example, or replacing a window with a patio door must be recalculated.
Some things may not matter to the building authority, but some do matter for structural engineers and KfW.

Exactly, that's what I'm saying.

Yes and no, you also said "or change the facade design," and that would also be the case with just a shifted window (especially if you don't shift a corresponding one). I welcome the attitude of the building authority if they don't want to see a formal change for that – that keeps things reasonable.
