Questione giuridica chiave
Whether Art. 19 and 20 of the city building code unlawfully conflict with cantonal building law and are therefore inapplicable.
Decisione estratta
The municipal provisions are not arbitrary and can validly complement cantonal law by regulating the height and placement of buildings, including aesthetic criteria for the lowest floor on sloping terrain.
Motivazione estratta
Cantonal law does not exclude all aesthetic references in municipal building rules. The challenged norms are limited to a specific aspect of construction and do not impose a general design regime beyond cantonal law.
