On which of these floor plans can we continue to build?

I didn’t draw the plan.
I just asked the architect if he knows [den Etos].
He knew him, and the plan came out.

Whereas the question arises whether the depth of 430 cm is sufficient?

Sufficient for what? Watching TV or for the kitchen?

Funny, you didn’t have those thoughts at 3.30 m – at least not for the kitchen, the dining area, but more the uncertainty that eventually the distance might be too large for watching TV.
Anyway: your cupboards have already been drawn by the copying architect. Fits. Do it.
However, I wonder why storage rooms are placed on the sunny side of the property and the living room in the east. Are the kids parked in front of the TV there for breakfast?
I would flip the house.

Since pretty much everything in here has been repeated about eight times, just this one remark:

If your daughters have inherited even a fraction of your decisiveness, the holy dining table will never have to be extended...!

If your daughters have inherited even a fraction of your decisiveness, the sacred dining table never has to be extended...!

Or rather every week, until they are old and gray...

Does structural engineering play a rather subordinate role in single-family house construction so that as a layperson you don't have to pay much attention to statics in the basic floor plan creation except for ceiling spans?

No. But in the upper floor in #278 the walls also give me the impression of being entirely non-load-bearing. With a flat roof as planned here, I don't see it working quite the same way, but with the "usual" hipped-roof city villa with a trussed roof, it does. So you are not doing anything wrong if you take structural engineering issues seriously.

What is it supposed to be enough for? Watching TV or for the kitchen?

For the general living feeling. That the depth is more than sufficient for the kitchen is clear. And also for the living area. In theory, you for the dining area.

However, I wonder why one puts storage rooms on the best side of the property and the living room to the east. Are the children parked in front of the TV there at breakfast? I would mirror the house.

I didn’t quite understand that either and have already asked to mirror the house. But you care lovingly about my little girls. Don’t worry, they won’t be parked in front of the TV.

holy dining table

I’m just saying that we only bought the dining area a few months ago and it’s not a must that all furniture has to be bought new. Apart from that, the 150 cm dining table was too small for the four of us and occasionally five. And even with our current 180 cm table, we sometimes wonder where the additional cm are.
