Waterhall Windmill

Waterhall windmill was the last working windmill to be built in Sussex. Construction of the tower started in February 1884 by a local builder named Hubbard. The well known Shoreham millwright firm J. W. Holloway & Son was employed to install the machinery and work was completed by February 1885. Sometime later, the tower developed cracks and required strengthening with a large iron hoop. This hoop remains as an external feature.
The mill has changed ownership many times since the departure of the Harris family. In the 1960s she was converted into a residence with the later addition of a modern extension. However, a surprising amount of machinery was left in place, including the windshaft, brakewheel and complete drive to the millstones. The millstones are still in place under a bedroom floor.
Many repairs have been carried out to the mill over the years, the most recent included the partial rebuild of the cap and replacement of the sweeps and stocks. These repairs were necessary following a storm in December 1990 when lightning struck the sweeps.
I spotted that it's back on the market for offers in excess of £1m if you're in the mood.
