Green Grove House is a mid-late 17th century, stone-built, two and a half storey, minor gentry house of 2-units. It has an end-chimney, is central-entry plan and has a stair-projection opposite the entry, similar in plan to Gelli, Trefilan. Green Grove was the former home of Morgan Lloyd, who was High Sheriff of Cardiganshire in 1677 (Blome list of 1673). The building is now used as an office of Aeron Valley Cheese.
