Description
Relley Mill House is a house built in the early 19th century, with some mid-19th century changes to its windows. The building is constructed of coursed rubble and features a Welsh slate roof with rebuilt brick chimneys. The front of the house is symmetrical, with two stories and three bays. It has flush quoins and a central, part-glazed six-panel door set in a raised stone surround, topped by a bracketed hood. On either side of the door are four-pane sash windows with flush wedge lintels and projecting sills. The central bay above is blank, flanked by identical windows. The roof has coped gables, shaped kneelers, and end chimneys. The rear of the house, which is partly built into a bank, has three stories at the lower end and features scattered windows. Inside, there is an early 19th-century dogleg staircase with stick balusters and a ramped grip handrail.
