Question juridique clé
Whether the planned facade openings in the barn are lawful in the agricultural zone given the unclear intended use of the stable.
Solution extraite
The factual findings were incomplete; it could not be determined whether the project served an agricultural horse-breeding operation or a non-agricultural recreational/commercial use, so legality could not be assessed on the current record.
Motifs extraits
The authorities failed to clarify the actual future use of the stable, the need for the works, soil-dependence, business plan, and possible nuisance to neighbors. Without this, conformity with the agricultural zone under planning law could not be reviewed.
