Cadw's description

On the N side of the house.

Probably late C18 and contemporary with the house.

A small water house of rubble stone with gabled slate roof. On the NW side is a stone-lintelled doorway, and on the NE side a stone outflow channel. A garden wall abuts the NE side. Inside it has a stone-lined tank.

Listed as an unusual and well-preserved ancillary structure to the Georgian house, and as part of a strong group of C18 house and outbuildings at Glanrhyd.
