Lock Keeper's House, Clachnaharry Sea Lock, Caledonian Canal, Inverness

The Lock Keeper's House at Clachnaharry Sea Lock on the Caledonian Canal is an early 19th-century cottage made of painted squared and coursed rubble. It stands two storeys high and features two windows on the ground floor along with a central piended porch, and two windows with piended dormer heads on the first floor. Lean-to outshots are present at each gable end. To the west, there is a rendered single-storey bothy with a piended slated roof and an attached brick stack. Both structures are set within a rectangular garden, mainly extending to the east of the cottage, and are partially enclosed by a coped stone wall.

The windows predominantly have 12-pane glazing in timber sash and case frames. The building has end stacks with clay cans and a pitched slate roof. There is also a later lean-to extension to the south.

The interior was observed in 2013, revealing that the former lock keeper's cottage has been subdivided, although the date of this alteration is unknown. The eastern half of the building is currently used as the sea lock and canal office by Scottish Canals, having been modified from residential use in 2005. The western half serves as a private residence.
