Kernrechtsfrage
Whether impaired views of neighboring properties caused by a new building constitute a legal ground to refuse the building permit.
Extrahierter Entscheid
No. Neighboring owners have no legal entitlement to preserve existing views against construction changes on adjacent land; such protection would require a relevant easement.
Extrahierte Begründung
The mere reduction of existing sight lines is not a statutory refusal ground under Art. 4 BauG. Protection of uninterrupted views can only be secured, if at all, by servitudes on the affected properties.
