Joiners Shop and former Implement Store at Gwysaney Saw Mill

The joiners shop is a 2-storey 3-window range of rock-faced stone with freestone dressings, and slate roof. Facing the yard on the S side are 3-light mullioned windows with hood moulds in each storey. In the L gable end is a basket arch to a wide doorway with a boarded sliding door to the R side. A boarded upper-storey door is directly above it in the upper storey. The ground level is higher at the rear, where there are two 2-light mullioned windows in the upper storey.

Against the R gable end of the joiners shop is a former implement store, the centre and L side of which was formerly open-fronted but is now infilled with corrugated iron sheets and glazed panels. The wall is rubble stone on the R side, and to the gable end.

The joiners shop has a 3-bay roof with king posts and raking struts. The implement store has a similar 6-bay roof. The trusses in the latter are carried on a long timber wall plate to the front which is supported by a single cast iron column now concealed behind the corrugated iron sheeting.
