The exterior dimensions are not one hundred percent fixed. We are flexible inside. But the house will end up with roughly these dimensions. I don’t understand your second answer about the height difference :). A photovoltaic system is supposed to be installed at some point, but my information is that a west-facing roof is just as suitable for this as a south-facing one.That sounds like a specific house model - then it certainly has a specific layout (and rooms for which their window side(s) are not indifferent). ... which to me sounds like a low probability of being able to neglect the height difference factor. Based on this half-fact basis, my answer can at best be "42" ;-)
If you have a better idea regarding parking spaces for cars, I am open to everything :).South-facing windows and no south-facing terrace are not mutually exclusive. South-facing terraces are usually too warm. The garden is in the west. Why do you want to use the entire street front for parking? Carports darken the windows of the house
The development plan is ancient. To put it plainly, I can pretty much do whatever I want. The floor plan is attached. However, it is not yet completely fixed. Depending on the orientation of the house, I could also swap the kitchen with the "living" area. Then the kitchen and utility room would practically face each other separated by the hallway. In this variant, the house would then (mirrored) have the roof side facing the street. I generally want the kitchen to be in the southeast and the living area adjacent to it in the south/west.What does the development plan say? What is the floor plan? If there are measurements, there must be one.
