The building is a single-storey boiling house with an attached privy and shed, located at Caerau. The main structure features rubble walls with widely slobbered mortar and a grouted roof made of old small slates. It has a tall central chimney stack topped with a thin capping, flaunching, and a red pot, which marks the gable end of the original free-standing boiling house.

To the right (south) end of the boiling house, there is a storage shed with a single doorway on the left side of its main elevation. At the left (north) end of the boiling house is a former privy, which has rendered walls and a corrugated iron roof, featuring a modern boarded door with the date '1936' above it. Additionally, attached to the right (south) end of the storage shed is a second shed, which is timber-framed and clad in corrugated iron.
