Top Lock House

Top Lock House is a lock keeper's house with an attached office, now a shop, likely built around 1816. It features coursed squared sandstone and a stone slate roof, situated on the slope of a canal embankment. The building is single depth with three bays, and the office is located at the left end. The front is symmetrical with two storeys, while the rear has three storeys. It has gable chimneys, a central boarded door with a plain stone surround, two windows on the ground floor, and three above. The side windows each have two sashed lights, and the window above the door is a four-pane sash. The single-storey lean-to office at the left end has a similar door on the left and a sashed window without glazing bars. All windows are fitted with stone sills and heads. This house is part of the Johnson's Hillock lock group on the Leeds-Liverpool Canal, with all other elements of the group listed in Whittle-le-Woods.
