The monument consists of a roofless ruin of a substantial stone building. The building forms a T shape in plan, with an east-west block measuring 15.25m x 7.4m, and a north-south block at the eastern end, measuring 11.2m x 6m. It has been interpreted as a residence, with a service and hall with central hearth, and a chamber to the east with a large southern window opening.

The monument is of national importance for its potential to enhance our knowledge of settlement and domestic activity. It retains significant archaeological potential, with a strong probability of the presence of associated archaeological features and deposits. The structure itself may be expected to contain archaeological information concerning chronology and building techniques. A house may be part of a larger cluster of monuments and their importance can further enhanced by their group value.

The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
