The monument comprises the remains of four circular/rectangular earthen building platforms, which probably date to the medieval period. The house platforms are large, averaging 12m by 7m in size and were probably built to support timber buildings. They are situated on the east facing slope of Mynydd Drumau.

The monument is of national importance for its potential to enhance our knowledge of medieval settlement. The monument forms an important element within the wider medieval context and the scheduled area may be expected to contain a wide range of archaeological information, including chronological detail and evidence in regard to construction techniques and agricultural methods. House platforms may be part of a larger cluster of settlement 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.
