Description

The Well House at Annables Manor is a Grade II listed building dating from the late 17th century. This single-storey structure features flint rubble walls with red brick piers at the corners and has a plain tile roof. On the north side, there is a 20th-century weatherboarded gable that serves as the entrance. The building has a canted plan with two bays.

On the south side, there are two glazing bar casements, while the east gable end has a 19th-century half-glazed door. Inside, the well house contains a large timber donkey tread mill for a deep well, located on the right side of the wheel. The tread mill features a timber wheel that measures twelve feet in diameter, with twelve chamfer-stopped spokes connected by dove-tail joints to the outer and central wooden rings, and reinforced with cast iron strengtheners. Above the well, there is a large axial turning beam set within a 17th-century red brick well surround. The roof structure includes tie beams and angle struts supporting the mid-height purlins.
