Of rubble with boulder foundations to the N gable and with slate roof. 2 wide, depressed-arched cart entrances at the upper end (L) with dressed stone voussoirs. Entrance to R with flanking windows, formerly also entrances, though altered C19. Paired entrances to R with further flanking windows. All openings have cambered heads with voussoirs as before; pegged oak frames and latticing to windows, boarded doors. 4 windows under the eaves, the upper 2 latticed, that to the R open, and the third with boarded internal shutter. Later rubble gabled extension to the rear at the NW angle; 2 further cart entrances. Mono-pitched rubble extension to S gable, projecting slightly to farmyard side where there is a plain entrance.
