Two small, single-storey red-brick buildings situated in front of warehouses on the west side of the Bute East Docks (NPRN 34242) at the southernmost terminus of the railway. The north building had a gabled slate roof with yellow brick window heads and jambs. The smaller building to the south had a hipped slate roof and ashlar quoining at the corners and around the windows. They were likely constructed around the turn of the twentieth century. They were photographed in the mid-1980s but have since been demolished.
