Kernrechtsfrage
Whether the rooftop hedge is a structure requiring a building permit under Art. 22 RPG
Extrahierter Entscheid
The hedge is a man-made, durable rooftop installation with significant spatial effects and is therefore permit-required.
Extrahierte Begründung
Its size, placement at the roof edge, and density create the visual impression of an extension of the building and materially alter its external spatial appearance.
