The remains of a platforms house, possibly dating from the seventeenth century, consisting of very massive walls of large boulders. The fire place was in the north-west gable-end and sunk 4ft (approx. 1.2192M). The doorway is 5ft (approx. 1.524m) high. The house was already in a ruinous state by the 1950s.
