Floor plan city villa approx. 140 sqm - tips, suggestions?

And again this *censored* city villa with a square floor plan, which really only fits optimally on the fewest plots.

My God, just leave this building style alone if it doesn't work. Usually, a rectangular floor plan fits better and a normal gable roof is also usually much cheaper than these tent roofs.

Since you have obviously already decided on a general contractor: is the shape of the city villa fixed or are there still possibilities for variations?
I am not sure whether the requirements here reflect the wish of the original poster or the development plan.

As long as the OP does not move away from the requirement to orient the living spaces to the north, no one in this forum will be able to get excited about their plan anyway – if we're being honest.

The view of the street or entrance to the living spaces can be interrupted by a hedge or gabions

The living spaces face north, the garage the beautiful west.

The higher ceiling height is not necessary. Our room is larger and yet the ceiling does not feel oppressive.

The technical room will not work. It is too small for house connections, fuse box, ventilation, heating technology, washing machine, and dryer.

The bathroom upstairs is simply a leftover piece and you can tell. Swapping the shower and toilet might help. Whether this thin wall by the sinks will work is questionable.

Take a pencil and graph paper
Draw your plot, your building window, possible house sizes, then the rooms
Look at floor plans. The big prefab house companies have many online.

Place the kitchen in the south and the living spaces in the west

So, we were able to agree with the municipality to change the plot. It is located directly opposite on the other side of the street. 550 sqm, offers less privacy, since it is built on by neighbors from the south, east, and west. But we can improve this with clever planting. An entrance on the north side would now be possible.

I have also tinkered with the floor plan again, probably still not perfect, but an improvement over the previous ones - in my opinion.

I know that one. It has already been discussed back and forth.

As a layperson, I would advise at least swapping the kitchen with the living room.
Reason: evening sun / west sun can usually be enjoyed longer – if you are working – than the eastern morning sun. So move the living room to the sweet spot southwest and place the windows there.

Child 2 would have only a north-facing window.

I'll leave further criticism to those who have at least some knowledge of the subject.
