Key legal question
Whether Art. 19 and 20 of the city building code unlawfully conflict with cantonal building law and are therefore inapplicable.
Extracted holding
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.
Extracted reasoning
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.
