Kernrechtsfrage
Whether the AI must pay the architect fees for the planning phase of the home adaptation.
Extrahierter Entscheid
No. The architect's participation was not necessary; the costs were not directly linked to a structural modification of the building and could be handled by a building professional or as advisory work already covered elsewhere.
Extrahierte Begründung
There was no alteration of the building structure. The works were not so complex as to require an architect, and coordination could reasonably be assigned to a building professional. The cantonal court's contrary finding was manifestly incorrect.
