Hello everyone,
We are planning to build a semi-detached house together with a couple of friends.
The currently permitted roof pitch according to the development plan is 25 degrees. The planned semi-detached house will have 1.5 stories.
I am concerned that a roof pitch of 25 degrees combined with a knee wall height of about 1.20–1.40 meters (4–4.6 feet) will result in very low ceiling heights.
Therefore, my question:
Is it possible to change the existing development plan, or can this be requested separately as part of the building permit / planning permission process?
Best regards

Larger floor area on the ground floor, nice mono-pitched / stepped upper floor – this can also create an attractive semi-detached house design.
How large is the plot and the building envelope / building plot?
Have you already calculated how much space you have available?

The site coverage ratio is 0.4. Is there also a specification for the floor area ratio?

According to the seller, it is permitted to develop the attic to 75% of the ground floor living area. Depending on the federal state (elsewhere it may be 2/3), this is the limit at which a pitched attic would count as a full floor, which with an "I" in the zoning plan would mean it is too large. This does not necessarily mean that a floor area ratio of 0.7 can be derived from the site coverage ratio of 0.4.
Often, a floor area ratio is no longer specified because its limitation is already effectively defined.
For example, if the site coverage ratio is 0.4 and the floor area ratio is 0.6, then you could, for instance, fully use the half-story limit upstairs and end up with about 0.34 downstairs, or fully use 0.4 downstairs and add only 50% upstairs.
Most recent zoning plans designate "ED" as an acceptable house type in most zones, simply because there is currently a generation without access to building savings contracts, who demand especially plots under 400m² (about 4,300 sq ft) due to budget constraints.

Each party can build 90 sqm on the ground floor A 225 sqm plot with a floor area ratio of 0.4 would allow 90 sqm of built-up area (not to be confused with living area).

and according to the seller, an additional 75% in the attic. The percentage likely refers to the full-story threshold defined by the state building code. This does not mean that the local zoning plan actually permits that large an attic space, nor that it allows the knee wall height required for such a size.
Sellers of small plots often overstate their development potential.
