Over the high garden wall is a row of terraced cottages that I believe were originally built for the servants who worked in the house and its gardens. Most of the chimney pots there have been replaced, some of them by stumpy little modern designs which might be practical but offer little in the way of architectural interest, but there's one in Doric, or Egyptian style (right), that must be very old.
My brother-in-law who is a builder had been salvaging any Victorian chimney pots that he was asked to replace and he'd put them together, with some potted herbs, outside the back door. One evening his wife looked out and a man was loading them into the back of a van. When she asked what he was doing he nonchalantly closed the van doors and drove away with the collection.
