Kernrechtsfrage
Whether the appellant had standing to object and appeal against the building permit under cantonal and federal planning law.
Extrahierter Entscheid
She had standing because the disputed construction affected her both legally and factually as an adjacent landowner, especially regarding boundary setbacks and her private interest in the lake shore.
Extrahierte Begründung
Setback rules under cantonal law protect neighboring owners and apply regardless of whether the neighboring parcel is fully buildable. A neighbor need not show an additional special factual interest when the construction violates such public-law setback rules; legal and factual interests sufficed here.
