Hello Neige,
starting from the top left: 1.31.5 m to the window; then 1.76 m the window, then follows an approx. 3 m long wall section, a floor-to-ceiling window 1.76 m wide and another approx. 60 cm wall to the end of the house.
Below starting from the left wall: 1.13 m wall, then 0.885 m passage/sliding door; 25 cm in full wall thickness of 17.5 cm and the niche is 1.12.5 m wide with wall thickness of 6 cm.
I hope I described it understandably, I have to draw it neatly and dimensioned sometime.
Best regards!
Edit: I have attached the ground floor, although the floor plan is no longer 100% accurate. 12.50 m house length is still correct, but the wall between the study and the kitchen is not at 3.51 m, but already at 3.01 m. We moved it in favor of the kitchen. The window is, as said, 1.76 m and not 2.01 m. Position and dimension of the window on the wall in the living area is also no longer correct. Otherwise, the floor plan at least still gives an idea of the room layout as well as house width/length.
