The Archdeacon of Canterbury's House

The Archdeacon of Canterbury's House, built by Prior Chillenden around 1400, originally served as guest lodgings and includes parts of the monastery kitchen and Pentise Gatehouse. The east end has been rebuilt using original materials after sustaining war damage. The building has two storeys and is constructed of flint, brick, and some reused medieval ashlar, topped with a renewed tiled roof featuring four hipped dormers.

On the first floor, there are three cambered sash windows. The ground floor includes three double lancet windows with hood moulding and one triple lancet window. The rear elevation is partly timber-framed and plastered, with sections of flint and stone. A projecting timbered gable is located at the west end on the second floor, while towards the east end, there is another gable with a projecting bay window supported by two wooden columns. One window from the 15th century features two trefoiled headed lights, while the other windows are 18th century sashes. A massive chimney stack made of flint and ashlar is also present. Inside, there is an overmantel dating from around 1600 in one of the rooms.

The building is part of a group that includes Nos 20 to 29A (consecutive), Pilgrim's or Pentise entry attached to No 29, a wall in the garden of No 29, wall and gatepiers between Nos 28 and 29, the Gateway from Green Court, and the building adjoining to the left, which is the King's School Library and Norman staircase.
