Kernrechtsfrage
Whether the 1.4 m horse fence outside the building zone was subject to a building permit.
Extrahierter Entscheid
Yes. The fence was a structure with significant spatial effects and therefore required a permit under federal planning law.
Extrahierte Begründung
Zäune can fall under 'bauten und anlagen' when they materially affect the landscape; this fence clearly changed the landscape image.
