I did not mean a note of thanks, but rather a response to questions / speculations / suggestions.

after all the floor-to-ceiling windows come. They take up your floor space

Well, at the top they certainly have less justification. Downstairs, I don't see a lack of floor space, but options to go outside.

Floor-to-ceiling window office... I would basically reconsider the window position there.

I would do the same in the living room: centered windows are often not pleasing. You rather go for the golden ratio or here 80cm at the planned TV wall.

The contract doesn't even include the windows drawn in the floor plan, only the calculated minimum that is legally required.

Amazing! That such a thing exists.
I praise our general contractor, who didn't charge any extra for windows at all, even though we took quite a few and custom windows additionally.

It was the same with us. There was no price difference whether window or wall.

For us, it was the same. It made no price difference whether window or wall.

I also don’t know what it depends on or depended on: we had an unusual general contractor. They were architects who acted as general contractors with model houses. I also have patio doors everywhere. In some cases, I wanted a windowsill knee-high in the west, but the seller said, You don’t want to take away the possibility of going into the garden on the west side. And he was right. Then a ribbon window here, two instead of one there, an asymmetrical one at the roof ridge. Altogether 4 exits in the open-plan living area, the main thing being that it doesn’t affect the statics . . . only the skylights cost.
It is a good lever for a GC to maximize profit.
However, of course, every window should be well and usefully placed.
