If you read the comments by fans of "The Good Witch" movies, you pretty fast realize that Grey House is more than just a house. To many it is one of the things that come first to mind while thinking about the movies.
Maybe some of you have wondered if Grey House is a real building. Yes it is, it was build in the 19th century and is located in Dundas, Ontario (where the movies are filmed) and is known as Foxbar.

On the following pictures you can see what the Prodcuction Team did to make Foxbar look like Grey House in the very first Good Witch movie.
