Questione giuridica chiave
Whether the planned cellar was permissible as a zone-conforming agricultural building without a special permit.
Decisione estratta
No. The parcel was not in a legally designated agricultural zone, so no zoning compatibility could dispense with a special permit.
Motivazione estratta
Solothurn had no agricultural zones designated by land-use plans; the area was simply outside the building zone and also not an agricultural area under the cantonal plan. For all buildings there, a special permit under Art. 24(1) RPG and § 38 BauG was required.
