Floor plan of a small single-family house on a north slope 170m²

Apparently the photos were deleted, no idea why...

Were they possibly hosted elsewhere instead of being uploaded here?

No, I don't think so, because the user haydee had obviously seen them, otherwise he wouldn't have been able to give his opinion on the floor plan. But whatever, now I have entered them again.

Sorry, in case my post is off-topic. As a silent reader, we are currently also working on our planned floor plan; before presenting it, I would like to inquire about the program used here? Especially regarding the exterior view and dimensioning, I have not yet found an optimal solution... Many thanks for the feedback!

No problem Construbo
This is AutoCAD, rather a more complicated program for technical draftsmen, so unfortunately I cannot recommend it to a layperson.

A great program is called "scribbling analog," whether with a pen or pencil, preferably on graph paper, taken with a phone and posted here. The less drafting experience you have, the more likely it is that the first version is still not very good. By the way, professionals NEVER make a framing-worthy, thoroughly elaborated presentation on the first try – that is more of a super high-definition amateur quirk.

however, we would then have no southern windows at all

Is the north arrow on the property correct? You walk around the house once to get to the entrance, while also having to pass a staircase? If it is indeed the case that the street is to the south and the garden to the north, I would at least mirror the living level so that you get the western sun into the open-plan living area. The sleeping area can then gladly be placed in the east.
