Good morning,

it would be new to me that the FH is calculated "only" from the wall height

That should be the most significant influencing factor, right?

Hello everyone,

it may be that I am completely out of sorts today. For me, the FH - at least so far - is the result of the combination (addition) of story height, possibly [Drempel], and roof pitch.
