1. Mid 18th century.

2. The 1st, 2nd and 3rd editions of the historic 25-inch O. S. maps, published in 1889, 1900 and 1915 respectively, depict a leat diverting water from the stream high above on the valley side to a small pond, from which a sluice controlled the flow of water to a point at the south-west end of the building group. This suggests that water power was used at the site, probably to drive machinery for processing animal feeds.
