Hello everyone

My wife and I have purchased a plot of land and are currently trying to obtain a building permit/planning permission according to our plans. There is no development plan. The only regulation in place is a statute governing roof pitch and roof shape. Our plans deviate from the statute regarding the roof pitch. The statute requires a roof pitch (gable roof) of 50°-55°, while our plans specify 38°.

The neighboring house (in the same building zone) also has a roof pitch of 38° and was built before the 2012 statute.

The statute states:
"By way of exception, different roof pitches and roof shapes are permitted for building extensions and existing roofs that already deviate."

As a layperson, I understand this to mean: if there is already a house with a 38° roof pitch in the building zone, then this is also permitted, right?

Thank you in advance

Hello,

sorry, but I cannot agree with your assessment.

I would interpret the regulation to mean that different roof pitches or roof designs are only allowed when an extension is added to an existing house that already has a roof pitch deviating from the regulation.

My recommendation in this case would be to contact the responsible building authority directly and present your wishes in a personal meeting to ask for an evaluation of the approval prospects. We had very good experiences with this approach at our building authority—our building plot is located in an existing residential area without a development plan, so Section 34 of the Building Code applied there.

If the building authority is not willing to attend such a preliminary meeting, you can still submit a planning inquiry to clarify whether your proposal is likely to be approved—this is usually less costly than risking the rejection of the entire plan.

Best regards,

Dirk

Thank you Dirk for the quick response.
I think your assessment is unfortunately correct. I will inquire at the building authorities.
In the worst case, it will be a house with a roof pitch of 50° (50°).

Hello,

in our case, the building authority really worked with us in a very constructive way.

We were allowed to rotate the roof ridge by 90°, significantly increase the knee wall height, and implement other very individual solutions.

Just ask what possibilities the building official sees – if the neighboring house also has a roof pitch of 38°, the chance that you might be allowed to build something similar should not be impossible.

Wishing you the best of luck!

Regards,

Dirk

Was the height of the knee wall explicitly specified? Did raising it change the number of stories?

Thanks and best regards

Hello,

No, there were hardly any regulations because there was no building plan / planning permission for the area – most of the houses date from 1950 to 1955.

However, the “old” house (which we demolished) had a knee wall of about 60 cm (24 inches), just like the other old houses around it.

Since there are already newer houses on the street with higher knee walls, we were able to use those buildings as a reference.

Despite the higher knee wall, our house is still considered a 1.5-story building.

Regards,

Dirk
