Today, the east range holds the entrance archway.
It was constructed around 1500 and contains three bays.
The modern gatehouse, at the northern end of the east range, has a lancet window in its east wall.
It has a jettied wooden frame upper part standing on stone walls.

South of the archway, the wall was timber framed but later partially infilled with brick and rubble as far as the chimney, where it joins the south range.
This timber framed wall is on a different alignment than the gatehouse, probably to unite with the south wall of the southeastern block, which originally may have been part of a wall around the courtyard before being incorporated into the building.

The roof of the southern bay of the east range was black-smokened and may have served as a kitchen or brewhouse at some time into which a chimney was later inserted.
