ᐅ Difference in zoning plan regulations for ground floor, roof, and single-story buildings

Hello everyone,

I’m so glad this forum exists.
I’ve already been able to read through quite a bit.
As a complete beginner in house construction, I have a few questions regarding the development plan. I haven’t had the chance to call the building authority yet, so maybe I can use Sunday to gather some ideas. For the descriptions of suitable plots for us, it says:

WA1 (general residential area according to §4)

E (only single-family houses allowed)

Floor area ratio = 0.3 (floor area ratio as an upper limit here, maximum floor area ratio 0.3)?

° (open building style according to §22)

I+D (number of permissible floors here: ground floor + convertible attic and knee wall)

SD (gable roof)

My problem now is that we would like to build a single-story house with a gable roof!
We don’t like flat roofs.
This is basically not permitted for the plots we like best.
Are there any options?
The knee wall must be max. 50cm (20 inches)
And the maximum wall height 4m (13 feet)
Roof pitch for two-story houses: 0–28 degrees
For single-story: 38–48 degrees.

I’m totally confused.
Is there a difference between ground floor + attic and single-story?
Could I keep the knee wall very low and the roof as flat as possible to avoid needing to use the attic as living space?
Or is the rule based on the “average house” with living downstairs and bedrooms upstairs?

As you can see, I have many questions.
Thanks in advance for your experience and help!

Where is the problem?

That sounds like an issue for the gable roof, but where is that stated? It seems to contradict the permitted roof pitch for a "single-story" building.

In my opinion, it looks like you can build a single story with a finished attic or with an unfinished attic. Or where exactly is the catch I might be missing?

Hello,
thank you for your help.
Yes, the issue with the hose is my problem—I simply don’t have enough vapor yet.
The woman from the building authority told me that a bungalow is not allowed here (due to the specified Franconian building style, meaning knee wall maximum 50cm (20 inches) and roof pitch between 38 and 48 degrees), if I understood correctly...
This is what the development plan says:
"For construction style ground floor and finished attic with knee wall," a maximum wall height of the main buildings of 4.0m (13 feet) is permitted.
I would have really liked to build an angled bungalow...
Thank you

The floor area ratio depends on the size of the plot—0.3 of it.

You can build a full story and have just an open-plan room under the pitched roof—you don’t have to call the house a bungalow just because all the main rooms are on the ground floor.

Best regards, Yvonne

The issue with the wall height can’t be correct as stated, or does that only apply to the eave side of a pitched roof?

And why is the knee wall supposed to be a maximum of 50cm (20 inches) high when two-story buildings with shallow pitched roofs are allowed anyway? I have a bit of the impression that you might be mixing things up here and/or presenting your interpretation of the development plan instead of the exact wording.

However, I believe you are mixing up the information from the development plan. On the one hand, you write: l + D... One full storey plus attic... further down, a sentence refers to 2 full storeys???

Regards, Yvonne
