Hello Thomas,
our house was also planned and built in an area without a development plan, i.e. according to §34.
Therefore, we first looked at the houses on the street regarding:
- Ridge direction
- Distance from the street
- Eaves and ridge height
- Dormers
- Roof pitch
- Knee wall height
Then we thought about how we roughly wanted to design our house and went with these ideas fixed in writing to the head of our building authority to ask what was possible and what was not.
This conversation was worth its weight in gold, as the gentleman from the building authority gave us many very valuable tips regarding the possible placement of garages, knee wall height, and terrace construction.
Also, in the subsequent building permit procedure, he adhered 100% to what he had promised us in advance. Our building application was even approved directly without involving the building committee of the municipal council – the construction project was merely announced for information at the next city council meeting.
Therefore, I can only recommend you proceed in the same way initially.
If something then seems strange to you, the option of a preliminary building enquiry is still available to you – but, to my knowledge, this costs additional fees.
Regards,
Dirk
