Questione giuridica chiave
Whether the modified project complied with AEAI fire-safety distance rules after façade changes.
Decisione estratta
Yes. The northern façade could be treated as non-combustible and the southern façade as sufficiently compensated by the reduced wooden surface and masonry inserts.
Motivazione estratta
The AEAI norm and directives allow compensatory measures and leave the authority a broad margin in technical matters. Balconies were negligible or not relevant to the distance calculation, and the cantonal fire office's threshold of under 30% wooden surface was not shown to be inconsistent with the applicable standards.
