Questão jurídica principal
Whether the building permit had to be annulled because the project allegedly obstructed access and circulation safety.
Decisão extraída
The access remained sufficient under planning law; the authorities did not abuse their discretion in finding no unacceptable traffic-safety problem.
Fundamentação extraída
The sufficiency of access is assessed case by case under federal planning law and leaves cantonal authorities a margin of appreciation. Given the narrow but lightly used dead-end road and limited traffic, even reverse maneuvers did not make the access insufficient.
