Description
Llifior Mill is a Grade II listed building that features an original house at the center of the structure, flanked by a later cross-wing on the right, which includes a grain-drying kiln at the rear, and a mill building on the left. The house is timber framed with painted brick nogging and a plinth, displaying square panels divided into three bays by continuous vertical posts. It has a slate roof and a baffle entry against the gable end stack on the right. The windows are casement style, with two and three lights, and there are similar windows in gabled framed dormers within the roof. A brick stack with plain coupled shafts is present.
The advanced wing to the left has a return wall made of rubble stone but is faced in brick, featuring paired casement windows with chamfered architraves, which are characteristic of the Vaynor Estate. The axial stack in this wing matches the design of the main range. The mill to the left is constructed of brick and has a slate roof. It is two storeys with an attic, featuring a central doorway with a loading door above, flanked by fixed light windows on each floor, all with cambered brick heads. An overshot wheel is positioned against the left-hand gable, consisting of an iron wheel and a box trough that supplies water from a leat.
The mill retains most of its machinery, including three sets of spur wheels on a horizontal shaft on the ground floor, and two pairs of stones (one equipped with a lifting crane) on the upper stone floor, along with a wire machine. Flour and grain bins are suspended below the second floor. The drying kiln is part of the cross-wing of the house, featuring a small oven against the rear wall and a brick arched vaulted ceiling. The drying floor had perforated tiles supported by an iron framework, although the tiles are no longer in place.
