Kernrechtsfrage
Whether the municipal core-zone rule allowed a basement used as garage and cellar.
Extrahierter Entscheid
The rule was not arbitrary: it permits commercial use of basements in the core zone, not basements only if they are commercial.
Extrahierte Begründung
The wording and the cantonal building-law context support the interpretation that 'creation' and 'use' are distinct; the appellate court's reading was plausible and compatible with the text.
