Question juridique clé
Whether the appellants had standing to object to the revised building permit under federal and cantonal law.
Solution extraite
They did not show a sufficiently direct, special and practically relevant interest distinct from that of the general public; standing was therefore denied.
Motifs extraits
Although the parcels were relatively close, existing buildings intervened, the project would not materially affect view or openness, and the alleged extra nuisance from an additional villa was not substantiated as a special harm.
