Question juridique clé
Whether the municipality could, for district preservation, prohibit new roof forms in a homogeneous built-up area.
Solution extraite
Yes. The planning rules were based on a sufficient legal basis and remained within municipal planning discretion.
Motifs extraits
Protection of landscape, local and street appearance under cantonal planning and building law may include existing buildings and typological coherence. In a nearly uniform district of flat-roof villas, excluding new roof forms was a defensible measure to preserve the quarter's character.
