Lock House

Lock House is a lock keeper's cottage dating to 1826, with additions from the 19th century and later alterations. It was built at the north end of the lock on the west side, facing the lock itself. The front and sides are brick, rendered, and the roof is slate, with gable-end stacks. The building is a double-depth block, incorporating a later 19th-century extension and a parallel roof line, plus a single-storey extension at the north end of the front range with a hipped roof.

The front elevation has a doorway set within a raised surround of long and short bricks, featuring a flat arch above. To either side of the doorway are double-casement windows with horizontal glazing bars. The first floor has similar casement windows set within segmental arches. All window openings have projecting sills. The rear elevation of the 19th-century extension has segmental arches above a mid-20th-century central door and late 19th-century 2/2-pane sash windows. The north range features a segmental arch above a mid-20th-century window to the right of a 4-panel door, and narrow segmental-arched windows to the rear. The interior has not been inspected. Lock House is an historically important part of the significant group of buildings at Gloucester Docks.
