Description
Cwmbelan Mill is a two-storey building featuring a six-window range made of large blocks of random stone, topped with a slate roof and boarded eaves on the south side. The mill has boarded doors and three-light small-pane iron-glazed windows, with all openings having segmental brick heads. On the north side, there are doorways on both floors, with the third opening from the left likely serving as a taking-in door for the upper floor. The south side has a ground floor doorway located at the right end. A water-wheel, probably undershot, is situated against the left end of the south wall; while the ironwork remains, the timberwork has been lost. Three windows behind the wheel are partly infilled with brick and timber boarding, and some upper windows have lost their glazing. There are no openings on the west gable end, but there is a small adjoining range made of corrugated material with a slate roof.
Adjoining the mill to the east is the miller's house, which shares the same roofline and has been partly modernised. It features two rebuilt red brick eaves stacks at the east end, framing the gable. The wooden windows were installed around the year 2000. The front entrance is on the north side, consisting of a panelled door with an overlight offset to the right, and a small two-light casement window above. On the south side, there is a door and window beneath a wide segmental brick arch, offset to the left, with a small two-light casement window above. The east gable end has two windows with paired tripartite sash windows, all under shallow segmental brick heads, and a small blind opening with a similar head at the gable. The interior has not been seen during the resurvey.
