Questione giuridica chiave
Whether a derogation under Art. 24c LAT was available for the proposed conversion and enlargement.
Decisione estratta
Art. 24c LAT did not apply because the building became non-conforming due to abandonment of farming, not a change in planning law; in any event, the project far exceeded the identity-preserving limits.
Motivazione estratta
The provision covers only structures that became non-conforming because of a legal or planning change. The planned enlargement, added to the earlier 1985 expansion, grossly exceeded the 30% / 100 m2 thresholds, so the building's identity would not be preserved.
