FWIW, the way I look at the distinction between a new golf course and a renovation/restoration/"transformation" is whether at least half the golf course ends up being rerouted, i.e. whether the golf course has nine or fewer holes in the same positions as before.
E.g., the minimum-qualifying "new course" I've seen of late is Quixote in S.C., where Kris Spence retained the routing of the front nine (while redesigning the holes in those corridors) and basically blew up the back nine and routed it anew. To me, that's a new golf course.
With that new land and the consolidation of holes on the older corridors, Lac La Belle also fits my "new golf course" definition.
