The monument consists of the remains of several buildings of unknown character and date, including a barn, 100ft x 25ft, with opposing entrances in the long sides. Along the eastern side are two small buildings opening onto the passage and there is also a building with a barrel vault substantially intact. The southern part of the area is surrounded by a boundary wall standing up to 12ft. Elsewhere walls stand to 20ft and more.

The monument is of national importance for its potential to enhance our knowledge of construction techniques and settlement organisation. 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. The building may be part of a larger cluster of monuments and its 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.
