Kernrechtsfrage
Whether the refusal of the complementary building permit violated property rights and proportionality.
Extrahierter Entscheid
The refusal was compatible with the constitutional protection of property because it rested on a legal basis, served a strong public interest under the LDTR, and was not disproportionate.
Extrahierte Begründung
The LDTR aims to preserve existing housing conditions; the challenged terraces were not necessary and would qualitatively alter the apartments. The complainant did not show that the refusal exceeded the statute's purpose.
