Question juridique clé
Whether the roof elevation authorized under Article 7 RPGA was arbitrarily applied.
Solution extraite
The cantonal court's interpretation was defensible: Article 7 para. 2 RPGA does not clearly limit the increase to each roof element, and a transformed two-slope roof with the ridge raised by no more than 1 m can comply.
Motifs extraits
Federal review for arbitrariness is narrow; the appellant showed only that another interpretation was possible, not that the chosen one was untenable or arbitrary in result.
