This small farm building is very remarkable, containing two exceptionally well-preserved cruck trusses that are smoke-blackened suggesting that they once formed part of a medieval timber framed hall-house, originally open to the roof. The present building is not a surviving 1-bay hall-house (as at little Llwgy, Cwmyoy) but a shortened hall-house of at least 2-bays. The cruck truss at the south end, with tie beam and collar, would have been the gable truss of the former medieval hall. The `open' cruck truss at the north end has a collar, and spurs (in place of tie beam) and would have been the centre truss over the open hall. The building must have extended north by at least another bay, although the second gable truss no longer survives. In the early 17th century the external walls were encased in stone and the old timber-framed house was reconstructed to form a lofted stable.

Small early 17th century stable of rubble stone with a gabled slate roof. The south front is single-storey. The ground floor has an entrance doorway (right) and a 17th century, 4-light, diamond mullion with roll moulding. The opposing rear elevation is enclosed by a 20th century corrugated building at the back. Attached to the south gable is a 20th century shed with a corrugated iron roof, and attached to the north gable is a 2-bay shelter shed with a slate roof.

The interior is most remarkable, containing the smoke-blackened timbers and two exceptionally well- preserved cruck trusses of probably a 3-bay 16th century hall-house. Both trusses have a saddle. The gable truss has mortice holes in the soffit of the collar, where timber wall studs formerly ran to a lower tie beam. Mortice holes in the cruck blades of the opposing `open' truss show that it originally had a collar. There are two tiers of trenched purlins. The ground floor, west wall has blocked window opening with massive oak sill, and signs of a blocked doorway (right).
