Description
This former water mill is built from rubble stone and features a partially replaced stone slate roof. It stands three storeys tall with a gabled design aligned northwest to southeast, and includes a single-storey lean-to extension to the south.
The main elevation faces southeast and has a double door at the ground floor, a single loading door above, and a small window in the gable. The extension has an additional wide door. The southwest elevation of the lean-to displays one shuttered window and one blocked door, while the rest of this elevation is set into the rising ground, above which is the former mill pond. This side has two windows: a leaded casement on the left and a shuttered opening on the right. The northwest elevation contains the wheel-shaft and the wheel-pit below, featuring a shuttered opening on the first floor and a casement on the second floor. The control mechanism for the sluice gate is also visible here.
The main water wheel is partially intact and is a mixed iron and timber overshot wheel constructed in the rare "clasp-arm" style, with the iron reportedly cast in Brecon.
Inside, the mill has three floors with a straight flight of stairs against the southwest wall of the main building. It retains timber beams, joists, and floorboards. The machinery, which is of standard type, remains largely intact and includes two pairs of under driven stones on the ground floor, along with a flour dresser and a small cleaner.
