Melin Soch is named on all three editions of the 25-inch O. S. maps as a working corn mill. A 450 metre-long leat brought water from the Afon Soch to a mill pond, the walls of which survive in the garden. The mill was a two storey building of rubblestone under a pitched slate roof, built into the steep valley side, and with the water wheel, no longer extant, on the west gable. A one-and-a-half storey extension on the south side may have been a kiln. The whole building has been converted to a dwelling.
