Kernrechtsfrage
Whether the planned district heating connection could be permitted without a valid zoning/utility plan covering the route.
Extrahierter Entscheid
No. A building permit required a valid development plan and completed or secured external infrastructure; the project was not covered by the existing plan.
Extrahierte Begründung
The court held that the planned line largely ran over public land and was not a mere house connection. It would extend the network and pre-empt planning, so a new development plan was required first.
