Description

The Carthouse at Hafod is a building constructed from whitened rubble and topped with a slate roof, featuring old slates on the rear pitch. It has two large, plain cart entrances with boarded doors and exposed timber lintels. To the left, a flight of parapetted stone steps leads to an upper entrance that was once part of a granary, which is unusual as most buildings of this type have access at the gable end; this entrance also has a boarded door. To the right of the entrance, there are two 2-light windows with plain glazing on the upper floor. At the rear, there are later 19th-century catslide extensions with corrugated iron roofs, and a boarded door is located on the right return. The interior was not inspected during the survey conducted in February 1997.
