Key legal question
Whether the hotel extensions qualified for an after-the-fact permit under Art. 24 RPG as site-bound outside the building zone.
Extracted holding
No. The existing hotel-restaurant as a whole was not site-bound; therefore the disputed extensions were not entitled to a permit under Art. 24 RPG either.
Extracted reasoning
Strict requirements apply to site-bound status. Because the operation was not dependent on a location outside the building zone, especially for hotel and seminar use near Zurich, there were no particularly important objective reasons for this site.
