Oh yes, Manorfield Close - the old people's bungalows! There used to be regular mentions of the over 60s club and most of the people attending lived in Manorfield Close.
From my books (see below) I see the residents included Mrs Perkins, Peggy's mother, and Colonel Danby, who used to live with Great Aunt Laura Archer at Ambridge Hall. He should have inherited the Hall but Aunt Laura didn't sign the will, so it went to a distant niece who sold it to Lynda and Robert. [Col Danby was Ballard Berkeley, who was also the Major in Fawlty Towers.]
According to The Book of The Archers and The Archers Enclyclopaedia, Manor Court is an 18th century gentleman's house bought by John Tregorran from Ralph Bellamy in 1968. Ralph's father, Admiral Bellamy, lived there. [Never heard of him before!] It was sold when the Tregorrans left Ambridge in 1984.
I see there was also a Manor House, which is where Carol lived before she married John Tregorran. She sold it and I don't think it's ever been heard of again.
I am getting an image of a village where the houses just tiptoe off when they're not needed any more. The Cat and Fiddle used to be like that - its location was never the same from year to year.
