Spot on MartinR. Apologies for the Boughton mix up, I looked at Boughton under Blean...............
So this is on the A252 Canterbury Road between Challock and Charing:Great Paddocks Farm, high on the North Downs at Challock, is a manor house dating from the 17th century.
Given listed building status in 1957, it is a rare Grade II* property, which means it is classified by English Heritage as a “particularly important building of more than special interest”.
English Heritage records that the red brick house is early 17th century with alterations in the 19th and 20th century, noting wooden mullioned windows and an interesting gabled roof. Look upwards to see the chimney on the left is two lovely “coupled” chimneys, while on the right, you can see four quirky octagonal chimneys.
