Description
The Well House is a single-storey structure with a flat roof, surrounded by a bank on the sides and rear. The facade has been refaced in random rubble with wide joints, but it retains the original door and window openings. There is a central doorway with a flat head that contains a planked door, flanked by small square windows with wooden frames and metal grilles. The front angles of the building are curved, and there are retaining walls extending to the left and right, with the left wall featuring two buttresses. The flat roof is covered in concrete and slopes slightly towards the rear, sitting below the level of the surrounding brick walls. Square brick vents rise from within the side walls.
Inside, there is a full-width pool of tepid water. In front of the pool, there is a narrow area with a quarry-tiled floor, surrounded by a rendered kerb. Straight steps with metal handrails lead into the water on both the left and right sides. The interior walls are rendered, and there are three square blocked openings in the left wall, with the central opening being deeper and featuring a raked sill. There is a single large recess in the rear wall, which is partly submerged. A raised plinth is present on the right wall. The ceiling consists of concrete sections with cast iron cross beams and includes a hatch. When the pool is drained, it is said that there is a circular well beneath that is at least 20 meters deep, with spiral stairs leading down.
