This farmhouse/mansion featured in an episode of 'The Professionals' filmed in 1977 (unit base: Harefield Grove, near Denham). I've searched high and low for this too. I reckon its somewhere around Denham. Its one of those that I feel I've seen in something else ('Dads Army') - firstly, its huge, derelict then, so may be demolished (Halings House area) today. But this episode also had footage shot at Maidenhead, Slough and Thorpe park ski slopes, so could be anywhere on route to these from Harefield. Most of the pics show the back of the house, the only real clue being the narrow road and the turn in the road, as you look at the picture the road bears to the left quite sharply in the distance. I've tried the location manager Peter Cotton with this one, but he can't remember it at all. Neither can first ad Bill Westley, and I never got a reply from guest star Keith Barron. Been looking for this since 1999?
I'm writing a book on the show and this location is driving me crazy???
Thanks in advance people.
