A blocked-up door next to the fireplace was thought to have been a priest hole, but is more likely to have been the entrance to the first floor of the house from an external staircase before the wing was restructured, probably in the late 16th century or the early 17th century.North of the Chapel Room is the Paradise Room, whose name derives from the bed hangings which include embroidered images of Adam and Eve and their fall from paradise, as well as the use in Tudor times of the name "paradise" for a favourite room, often a bedchamber.

On the other side there is a small recess, which was described in an 1882 newspaper as "a dark passage which is said to lead to some region unknown".

The largest room on the first floor is the Withdrawing Room, situated above the Great Hall. It has an elaborate plaster ceiling, and the overmantel above the fireplace bears the arms of Queen Elizabeth I. The frieze of the Withdrawing Room incorporates shields of arms representing marriages of the Davenports.
