Key legal question
Whether the shed reconstruction outside the building zone could be retrospectively authorized as renewal rather than rebuilding.
Extracted holding
The works constituted a rebuilding, not mere renewal; because the building was not destroyed by an element event, no exception permit could be granted.
Extracted reasoning
Rebuilding exists when the substantially external building parts are largely newly erected. Here the roof and most perimeter walls were rebuilt, so the structure was mainly new. Under cantonal rules, rebuilding outside the building zone is allowed only after destruction by an element event; ordinary rain and gradual decay from poor maintenance do not qualify.
