Key legal question
Whether the setback under § 22 aKBV was correctly calculated for the stepped building and the new pavilion.
Extracted holding
The stepped setback rule also applies to a narrowly set-back upper storey on the side facade; a 3-meter setback for the pavilion was permissible.
Extracted reasoning
The illustrative annex shows stepped massing; upper storeys may have to respect the general setback table even where the lower part already meets the minimum setback. The authorities did not act arbitrarily in treating the pavilion as a second storey on a 10-meter building length.
