Glanffrwd Mill

The mill is a 2-storey 3-window range of rubble stone with larger quoins, brick dressings, and a renewed slate roof. The S front has camber-headed windows with 2-light small-pane casements renewed in original openings, and double boarded doors to the L. The rear wall, on the bank of Ffrwd Cynon, has fixed windows in earlier openings, below a line of projecting drains at ground-floor level. The waterwheel is detached from the R-hand (E) gable end, where there is a single 2-light first-floor window similar to the front, replacing a former first-floor doorway. The wheel is within a rebuilt stone-lined wheelpit and is a cast iron overshot wheel cast by Ellis Brothers of Aberystwyth, restored by the Outlane Engineering Company of Huddersfield. In the L-hand (W) gable end is an external stone stairway added in the late C20 with re-used materials, leading to a first-floor doorway, which is also a modern insertion using salvaged bricks for the cambered head.

Most of the interior detail is restoration work. There is a flagstone floor, replacing original cobbles, beneath which is the line shafting for the machinery. This was a scheme introduced during restoration, as the line shafting was originally overhead. The line shafting is new and the pulley wheels were salvaged from scrap yards during the restoration. The first floor has new floorboards and joists, reached by a modern dog-leg stairway. In the upper storey is a 3-bay roof with sawn collar-beam trusses, and the underside of the roof is plastered. All windows have fielded-panel shutters.

The mill has machinery on both floors. In the ground floor is the carding machinery, in the form of a picker cast by Rhodes & Son of Hope Foundry, Leeds, a scriber and a condenser, which were made c1860 and bought for the mill in 1884. All of this machinery has been restored. In the upper storey is a loom for weaving rugs, of unknown provenance, and a spinning jack brought from a woollen mill in Aberarth.
