Workshop, store and smithy at Neath Canal Depot

The building is a workshop, store, and smithy located at Neath Canal Depot, dating from the late 20th century. It is a single-storey structure divided into two units: a workshop on the south side made of snecked stone and a smithy on the north side constructed from rubble stone, placed end to end. A visible butt joint separates the two units on the west elevation, while the east elevation has been rebuilt in random rubble during the late 20th century. Both units feature renewed slate roofs, with skylights on the west slope.

In front of the workshop on the east side, facing the yard, there is a square open-sided canopy supported by rubble piers and topped with a pyramidal slate roof, mostly rebuilt in the late 20th century, likely used for storing timber. The workshop has two doorways facing the yard, while the smithy has a single segmental-headed doorway, all of which have been rebuilt and feature boarded doors. The north gable end of the smithy contains a blocked segmental-headed window, and the south gable end has a single loft opening under a lintel that is now boarded up. The rear wall of the workshop has a blocked window to the right, with its original head missing and rebuilt in random rubble. The smithy has two short square stone stacks rising from the eaves.

The roofs are supported by softwood trusses, and a dividing wall separates the two units, with the smithy at the north end being at a lower level.
