I'd get a nice plot of land with a chateau in the woods of Wyoming, near Yellowstone. That, or somewhere in the mountains of Colorado.
Very open to nature, perhaps a stream running through my property, heavily wooded at the perimeter, and I guess living out in the sticks I'd need a backup power grid as well of some sort.
That's my 'Win The Lotto' dream.
Either that, or moving to Northern Japan and opening a Brewery+Onsen in a similar peaceful wooded area/town.
