The monument consists of the remains of an extensive moated mansion that belonged to the Herbert family and thought to date to the 16th century. The site comprises a large rectangular flat area, measuring 54m NE/SW by 45m, and bounded on the N and E sides by a flat bottomed ditch that was originally a moat. The ditch on the E side is 5-6m wide and 2m deep with steep sides and a 1.2m high bank on the outside. On the N side the ditch is shallower and does not have an external bank. The remains of the house stand in the SW corner of the site and comprise the corner of the building. The N/S orientated section of wall measures 6m in length and between 2m and 3m high. The E/W orientated section of walling is 4m in length and up to 3m high and at the E end are the remains of a carved stone window. Carved and decorated rubble lies around the standing remains of the structure.

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.
