Watch House, Retaining Walls To The River And Garage

The Watch House, originally a customs house and now a private residence, along with its retaining walls to the river and a former boathouse that has been converted into a garage, dates back to 1850. The building is constructed from rubble with a hipped slate roof and has coursed rubble stacks. It is a single-storey structure set on a battered, dressed ashlar plinth facing the river.

The north-east elevation, which faces the river, features a layout of 1:3:1 bays, with the outer bays advanced as wings beneath hipped roofs and accented with quoins. The windows are glazing bar sash types set in dressed stone surrounds with cills supported on brackets, and the outer bays include tripartite windows. The battered plinth extends approximately 5 yards to the south-east, serving as a retaining wall for the garden.

The south-west elevation, which is the land-facing side, has an L-shaped plan with three bays, again featuring glazing bar sash windows in dressed stone surrounds with cills on brackets. There is a panelled door located in a projecting porch at the re-entrant angle, and another panelled door, which was formerly used as the customs office, is found in a projecting porch on the north-west gable.

Adjacent to the main building, about one yard to the south-east, is the former boathouse, now functioning as a garage. This structure is also made of rubble, with dressed ashlar quoins and voussoirs, a hipped slate roof, and a segmental headed doorway located at the north-west end.
