Hello everyone,
first of all, I would like to thank you all for the feedback.
Before we continue to consider a sensible room distribution and/or size, I contacted the city again by email regarding the flat roof topic. In this email, I specifically asked whether the implementation of the flat roof is possible.
Last year, I had already contacted the city by phone on this topic and received the following written response:
"...whether you choose intensive greening or extensive greening is up to you.
However, I would like to point out that with intensive greening, use as a residential garden is not permitted within the 3 m boundary distance area.
From the statute, there are no further specifications."
However, it is not clear which roof this refers to.
It is possible that I did not describe my concern specifically on the phone back then, i.e. the implementation of a flat roof (main roof area), or that it was misunderstood or not understood by the city. A written proof of my question is missing, as it happened by phone.
However, I do not want to look for someone to blame now, but rather await the city's concrete response.
