AbFab: Where is that English country house?

Hi, AbFab fans, right at the end of one of the episodes (I don't know which episode), Edina is sitting on the grass outside an English country house. You can briefly see the red-brick wing of the house behind her. The scene lasts only a few seconds. The episode had to do with yoga, spiritualism .... Does anyone know which country house it is? It's a real house, not a film prop. I've searched the Internet but can't find the house. I'd like to visit it the next time I'm in England (if it's open to the public). Thanks for any help you can give. Over and out, Rosemary.
