Hello everyone!
I have now supplemented my sketch with more detailed dimensions of the walls, windows, contour lines, and roof slopes. I have also marked all four cardinal directions.
:
Screed:
You are right, screed + ceiling naturally also need to be constructed. I would calculate at least 20 cm for "height loss," okay?
Roof pitch:
I have marked it in the sketch: 29.2 degrees
Living area
No, I have left out the balcony. It is about 12.5 m². But you are also right on this point; of course, I did not subtract the walls from the living area. Personally, I prefer to create a nice apartment rather than squeeze out the last square meter at the expense of an unattractive apartment.
Dormers:
I already had the idea of dormers six months ago but was then unsure about the costs involved and whether the structural engineering would permit a dormer. But it is certainly a very valuable point that would enhance the living space.
Best regards,
Flasher
