Question juridique clé
Whether the cantonal court arbitrarily found the planned works to be repair/transformation rather than reconstruction under Vaud construction law.
Solution extraite
The finding was not arbitrary; the remaining walls were usable and the works could be treated as repair or transformation within the existing volume.
Motifs extraits
The court held that neither reconstruction nor transformation requires preservation of interior structures. It relied on local inspection findings and found the engineer's late report insufficient to overturn them.
