The monument consists of the remains of ten platform houses. A platform house is a levelled area of ground on which a house is built and probably dates to the medieval period. The platforms are located on the southern slope of Mynydd Ty Talwyn, and are spread out over a large distance.

The monument is of national importance for its potential to enhance our knowledge of 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. A platform 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.
