You have it JW. An interesting place, apparently the old house was transported from Sussex and added to existing buildings, including a forge, some time before 1910. There was a bit more at the front but that was knocked down to provide the present hard standing.
If you view any of the estate agents details that appear online you will see that it is a substantial property with extensive gardens with good views. Obviously the further up the hill towards the ruined castle, the better the view.
The Edwardian pile, Thurnham Keep, allegedly built from spoil taken from the castle ruin is just over the road. I did do a preliminary survey in there, but it was too extensive for us, a commercial install rather than just a large domestic.
Carry on JW
