The Mansion?

Where is the real mansion used for exterior views of the Woodstone mansion.

I haven't seen any information on where Ghosts is filmed - New Ork City region, Hollywood, Vancouver, or someplace else.

I assume that the exteriors of the mansion were filmed near the interior filiming studios. So the mansion used for the exteriors should be somewhere fairly close to the city where Ghosts is filmed.

I don't recognize the masion as any that I have seen in other movies and tv shows.

Does anyone know anything about it?
