Description

The former Navigation Colliery Electrical Outbuilding is a small rectangular workshop with three bays, constructed of red brick. It originally had a Welsh slate roof, which is now missing, and the walls are no longer fully intact up to the eaves level. The building features a range of three round-arched window openings, with the center opening blocked and a lintel positioned below the sill. The other windows still retain some of their former multipane metal frames, although part of them is blocked. There is also a round-arched doorway on the left that is now blocked. The outbuilding has a raised eaves band and quoins, showcasing a simpler version of the decorative brickwork found on the larger buildings nearby.
