Planning with an older development plan

they only position themselves crosswise when the ridge direction is rotated by 90 degrees

Well, it’s rather you who are being obstructive… *SCNR*

Especially because we are building on a curve, it is very important that the ridge matches the street :p We could also build a hip roof with a super short ridge in the “correct” orientation, but it would just look really stupid among all the gable roofs :rolleyes:

Just say what your desired deviations are.

Conversion of the attic (our 2nd full floor), knee wall 2.75m

I vaguely remember you having a bungalow (?)

Say what your desired deviations are.

Higher knee wall & associated lower roof pitch as well as more roof overhang. Those would be the most important points for us.

Higher knee wall & thus less roof pitch

Sounds at first just contradictory ...

as well as more roof overhang

... as well as in this triad usually with little prospects. This combination goes in three out of three points in a direction that touches the "regional typical character," with which such specification combinations are usually justified. Read the justification for the development plan, if it has already been "digitized" for such an "old" specimen.
