Between the mill pond and the head of Robins Creek are a group of two buildings. These comprise a long, single-storey, workshop building to the S and a large double-height building with a single-storey western range to the N. The southern building with its northern range is shown on the 1864 OS map and expanded westward on the 1898 OS map. By the 1939 OS map it had again been reduced to its current footprint. The northern building is probably indicated on the 1898 map as part of a larger complex of buildings. On a site plan of 1922 most of this complex had been demolished. The current buildings are marked as a coal shed and adjoining locomotive shed. Tracks are shown entering the locomotive shed and an overhead gantry enters the N elevation of the coal shed. The southern range of buildings are now marked as stores. On the 1954 OS map the northern buildings are marked as a ruin. Location accurate to 2m based on available information.
