Kernrechtsfrage
Whether the metal roof covering could be authorized under planning and heritage rules.
Extrahierter Entscheid
No; the after-the-fact authorization and building permit had to be refused because the metal covering violated the applicable alpine heritage protection rules.
Extrahierte Begründung
The court upheld the cantonal view that the chalet’s protected substance included the roof and that the traditional shingle covering was part of its characteristic, protected value.
