Three storey water-powered corn mill of squared stone rubble construction under a pitched slated roof. There are cambered arched window and door openings. The water wheel was on the north wall and was fed by a substantial pond some 230m long supplied by the Afon Horon. The south west corner of the mill is chamfered at 45 degrees; in the angled wall is the main doorway above which is set a slate plaque inscribed:
" E / R A / 1823. / Na ladratta. " (in English, "do not steal").
Built In a similar style, a corn drying kiln adjoins the mill to the south and the two storey miller's cottage lies to the north east, although the latter has large straight stone-slab lintels to the openings.
