Description
Lock House is a cottage that has been extended to the left (south) and faces the line of the former Glamorganshire canal, set behind a front garden with a stone wall. The building is constructed from brown and grey squared rubble, featuring dressed quoins, while the left gable end is rendered. It has an artificial slate roof with end stacks made of snecked dressed stone.
The cottage is two storeys high and has a slightly asymmetrical front with windows and a door that are offset to the left. It has a two-window range, although the glazing has been replaced. The ground floor windows and the centrally located left doorway are set under stone lintels that are lightly scored to resemble voussoirs, and there is a boarded door.
The ground floor of the cottage has been converted into a single room, with stairs rising beside the fireplace. The central doorway is currently blocked behind a door.
