Kernrechtsfrage
Whether the retaining wall was a covered building component under the building insurance rules.
Extrahierter Entscheid
The wall was not a building component covered by the statutory building insurance scheme.
Extrahierte Begründung
It was not directly connected to the insured building and did not serve as a statically stabilizing element of the building; it was mainly built for the terrace/forecourt and terrain support.
