Kernrechtsfrage
Whether the cantonal decision on the building permit was a final or intermediate decision under Art. 90-93 BGG.
Extrahierter Entscheid
The decision was an intermediate decision because essential building-law questions and required detailed plans remained to be approved before construction could begin.
Extrahierte Begründung
The permit and later detail approvals were part of a staged procedure; reviewing the appeal now would risk multiple federal proceedings and inconsistent decisions, while the appellants did not show irreparable harm under Art. 93 BGG.
