Description
Treglum Mill Cottage is a former mill house, now a private residence, dating from around the mid-18th century. It is constructed of stone rubble and features a rag slate roof with gable ends and stone rubble end stacks. The building has a two-room layout with a cross passage, heated by end stacks, with the larger room likely serving as the hall-kitchen on the right side. A rear outshut was added in the 19th century. The exterior is two storeys high and has a slightly asymmetrical three-window front. There is a 19th-century part-glazed door located to the left of the centre, flanked by two 2-light casements on the ground floor, with two similar casements and a central blocked window above on the upper floor. The interior has not been inspected.
