Millfield House and adjacent mill buildings was leased from Sarah McClintock by George H. Mitchell at the time of Griffiths Valuation, when it was valued at over £17. It is still extant. The National Inventory of Architectural Heritage includes a detailed account of the now-derelict mill complex and notes its association with the Swan family in the latter decades of the 19th century.
