I need help understanding the development plan.
It states that only one full storey is allowed.
Is it then permitted to use 80% of the floor area on the upper floor?
Example:
440 m² (5304 sq ft) plot, floor area ratio 0.2 → 88 m² (947 sq ft) floor area.
Am I allowed to use 80% of this floor area on the upper floor (88 m² × 0.8 = 70.4 m² (758 sq ft))?
Thank you very much.
Best regards,
Arbeiter01

A floor area ratio of 0.2 results in a buildable area of 88 m² (950 sq ft).
You are, of course, allowed to add a habitable roof on top (provided there are no other regulations in the zoning plan).
However, this must not count as a full storey.
Please refer to your national or regional building code for the definition of a full storey.
You may also build the entire ground floor living space with a roof above it; the definition of a full storey always relates to the average ceiling height specified in the building code.
An attic is also possible in addition.

440 sqm (4,736 sq ft) x site coverage ratio 0.2 would result in 88 sqm (947 sq ft) of building footprint. Roughly estimating, I calculate about 71 to 74 sqm (764 to 796 sq ft) of floor area on the ground floor. I hope the site coverage ratio applies only to the building itself, and that the driveway, etc., can have an additional allowance.

State building code = state development regulations?
88 sqm (947 sq ft) floor area is clear.
But how do you arrive at the floor space on the ground floor? Is there a formula for this?
Or is there a link where I can read about this in detail?
Thank you

State Building Code means LandesBauOrdnung (each federal state has its own).
Very roughly, I calculate 80 to 85% of the footprint remains after subtracting the walls. The smaller the building, the closer the actual value tends toward the lower figure. These are just rough estimates, so I omit decimal places to avoid giving the false impression of precise calculation (for three-digit values, I also round to the nearest half ten). This cannot be found in any standard; it is more of an empirically verified guideline.
Instead of "rule of thumb," for this scale, "quarter pi" works approximately as a factor.
