Grand Union Canal Leicester Line Lock House, Watford Locks

The lock house at Watford Locks, built around 1815 with later alterations, is possibly designed by Benjamin Bevan and reflects a variant of the 'Old Grand Union' style. It is constructed of painted brick and features a hipped slate roof with a ridge stack and an outshut at the rear. The building is two storeys high and has three bays. The off-centre doorway is fitted with a 20th-century door and is sheltered by an open porch that has a pitched roof, largeboard, and finial. Flanking the doorway are two single 4-light casement windows with cambered arches. Above these, there are two slightly smaller, small-pane, 2-light casement windows, also with cambered arches. The cottage has significant group value with the nearby Watford Locks.
