The only surviving part of the monastic grange is the gatehouse, which is recorded in the National Heritage List for England as a designated Grade I listed building, and is one of only two surviving monastic manorial buildings in Cheshire, the other being Ince Manor.

[3] The manor of Saighton was held by the secular canons of St Werburgh in Chester before the Norman Conquest.

[4] The site was given a licence to crenellate in 1399, and this was confirmed in 1410,[6] but the privilege was apparently not acted upon: "Saighton was primarily an agricultural centre until it was converted to residential use in the fifteenth century".

[4] The monastic buildings, other than the gatehouse, were demolished in 1861[6] and were replaced by a house designed by Edward Hodkinson for the 2nd Marquess of Westminster.

The lower 1½ storeys of the front aspect are occupied by a pointed arch, above which are three narrow windows.

In the angle between the gateway and the newer building, on the left, is a square turret that is taller than the rest of the gatehouse.

This stands on bedrock on the edge of a rock cutting and is thought to have been a form of light fortification.
