Floor plan ideas for remodeling/renovation of 180 sqm

I have added labels for the ground floor to make it clearer - see attachment

E2 is the main entrance and E1 the secondary entrance? Show the sides as well, the front views of the mountain side and valley side only show the level across, but not the slope lengthwise.

E2 is the main entrance and E1 the guest entrance? Show the pages that display the front views, the mountain side and valley side only show the flatness across, but not the slope lengthwise.

Theoretically yes - but since both floors are to be used, E1 would then become the main entrance.

thinks that the pictures of you are distorted. Just keep rotating the camera until parallel lines appear.

I still haven’t really understood what you actually want. You are talking about a townhouse. Are there no photos of the existing condition?

In the plan, there are 2 apartments after all.
