[1] English Heritage Listed Building Number: 265325. First Listed on 05/06/1985. [2] Stone, Random rubble walls. Gabled roof [3] The mill probably dates to 1839 and is part of the Holnicote Estate, owned by the National Trust since 1944. It had been used as a barn by Horner Farm for many years and was in very poor condition. Modern agricultural practices meant the mill was unsuitable for use by the farm and so a 50 year lease was offered for sale by the National Trust in May 1989, for conversion to a private house. The lease remained unsold until it was taken on in October 1990, with works beginning in November 1990. The works aimed to maintain the mill's appearance and extensive repairs to the existing leat (with a new 150 metre section of tail leat in 1994 to bypass the original silted-up tunnel) restored the water supply to the mill wheel, a 5.49 metre diameter overshot with 56 buckets, although it was only permitted to turn occasionally. Further legal issues and a collapsed section of leat have meant the mill is currently waterless. [4] The building was visited in May 2012 as part of the rapid condition survey of Exmoor's Listed Buildings 2012-13. It received a BAR score of 6. [5]
