Questão jurídica principal
Whether the greenhouse was permissible as zone-conforming under planning law and the PAC
Decisão extraída
No. The greenhouse was a new construction and did not fall within the authorized categories of the protected zone; the cantonal court's interpretation was not arbitrary.
Fundamentação extraída
The court read the PAC provision in light of its structure, purpose, and the restrictive nature of protected zones. Allowing any agricultural building would undermine the protection of the landscape site.
